MOUNT-ZIP(1)

NAME

mount-zip - Mount a ZIP archive as a FUSE filesystem.

SYNOPSIS

mount-zip [options] zip-file [mount-point]

DESCRIPTION

mount-zip is a tool allowing to open, explore and extract ZIP archives.

mount-zip mounts a ZIP archive as a read-only FUSE file system (https://en.wikipedia.org/wiki/Filesystem_in_Userspace), which can then be explored and read by any application.

mount-zip aspires to be an excellent ZIP mounter. It starts quickly, uses little memory, decodes encrypted files, and provides on-the-go decompression and caching for maximum efficiency.

The mount point should be an empty directory. If the mount point doesn’t exist yet, mount-zip creates it first. If no mount point is provided, mount-zip creates one in the same directory as the ZIP archive.

USAGE

Mount a ZIP archive:

    $ mount-zip foobar.zip mnt

The mounted ZIP archive can be explored and read using any application:

    $ tree mnt
    mnt
    └── foo
    0 directories, 1 file
    $ cat mnt/foo
    bar

When finished, unmount the file system:

    $ fusermount -u mnt

  File Name Encoding

mount-zip is fully Unicode compliant. It converts the file names stored in the ZIP archive from their original encoding to UTF-8.

In order to interpret these file names correctly, mount-zip needs to determine their original encoding. By default mount-zip tries to guess this encoding using the detection feature provided by the ICU library. It can automatically recognize the following encodings:

•   UTF-8

•   CP437

•   Shift JIS

•   Big5

•   EUC-JP

•   EUC-KR

•   GB18030

•   ISO-2022-CN

•   ISO-2022-JP

•   ISO-2022-KR

•   KOI8-R

For example, when mounting a ZIP containing a Shift JIS-encoded file name, the encoding is correctly detected:

    $ mount-zip sjis-filename.zip mnt
    $ tree mnt
    mnt
    └── 新しいテキスト ドキュメント.txt
    0 directories, 1 file

This system is not foolproof, and doesn’t recognize a number of popular encodings. For example, when mounting a ZIP containing file names encoded in CP866, they are interpreted as CP437 and rendered as Mojibake (https://en.wikipedia.org/wiki/Mojibake):

    $ mount-zip cp866.zip mnt
    $ tree mnt
    mnt
    ├── äáΓá
    └── ÆÑ¬ßΓ«óδ⌐ ñ«¬π¼Ñ¡Γ.txt
    0 directories, 2 files

In this case, the user needs to explicitly specify the original file name encoding using the -o encoding mount option:

    $ mount-zip -o encoding=cp866 cp866.zip mnt
    $ tree mnt
    mnt
    ├── Дата
    └── Текстовый документ.txt
    0 directories, 2 files

  Name Deduplication

In case of name collision, mount-zip adds a number to deduplicate the conflicting file name:

    $ unzip -l file-dir-same-name.zip
      Length      Date    Time    Name
    ---------  ---------- -----   ----
           25  2021-10-29 14:22   pet/cat
           21  2021-10-29 14:22   pet
           30  2021-10-29 14:22   pet/cat/fish
            0  2021-10-29 14:22   pet/cat/fish/
           26  2021-10-29 14:22   pet/cat
           22  2021-10-29 14:22   pet
           31  2021-10-29 14:22   pet/cat/fish
    ---------                     -------
          155                     7 files
    $ mount-zip file-dir-same-name.zip mnt
    $ tree -F mnt
    mnt
    ├── pet/
    │   ├── cat/
    │   │   ├── fish/
    │   │   ├── fish (1)
    │   │   └── fish (2)
    │   ├── cat (1)
    │   └── cat (2)
    ├── pet (1)
    └── pet (2)
    3 directories, 6 files

Directories are never renamed. If a file name is colliding with a directory name, the file is the one getting renamed.

  Encrypted Archives

mount-zip supports encrypted ZIP archives. It understand both the legacy ZIP encryption scheme, and the more recent AES encryption schemes.

When mount-zip finds an encrypted file while mounting a ZIP archive, it asks for a password. If the given password doesn’t allow to decrypt the file, then mount-zip refuses to mount the ZIP archive and returns an error:

    $ unzip -l different-encryptions.zip
    Archive:  different-encryptions.zip
      Length      Date    Time    Name
    ---------  ---------- -----   ----

           32  2020-08-28 15:23   Encrypted AES-192.txt
           32  2020-08-28 15:23   Encrypted AES-256.txt
           34  2020-08-28 15:23   Encrypted ZipCrypto.txt
    ---------                     -------
          153                     5 files
    $ mount-zip different-encryptions.zip mnt

    Password > Got it!
    Use the --force option to mount an encrypted ZIP with a wrong password
    Cannot open File [1] '/Encrypted AES-128.txt': Wrong password provided

Providing the correct password allows mount-zip to mount the ZIP archive and decode the files:

    $ mount-zip different-encryptions.zip mnt
    Need password for File [1] '/Encrypted AES-128.txt'
    Password > Got it!
    Password is Ok
    $ tree mnt
    mnt
    ├── ClearText.txt
    ├── Encrypted AES-128.txt
    ├── Encrypted AES-192.txt
    ├── Encrypted AES-256.txt
    └── Encrypted ZipCrypto.txt
    0 directories, 5 files
    $ md5sum mnt/*

    275e8c5aed7e7ce2f32dd1e5e9ee4a5b  mnt/Encrypted ZipCrypto.txt
    $ cat mnt/*
    This is not encrypted.
    This is encrypted with AES-128.
    This is encrypted with AES-192.
    This is encrypted with AES-256.
    This is encrypted with ZipCrypto.

You can force mount-zip to mount an encrypted ZIP even without providing the right password by using the --force option:

    $ mount-zip --force different-encryptions.zip mnt
    Need password for File [1] '/Encrypted AES-128.txt'
    Password > Got it!
    Continuing despite wrong password because of --force option

In this case, the files can be listed, but trying to open an encrypted file for which the given password doesn’t work results in an I/O error:

    $ tree mnt
    mnt
    ├── ClearText.txt
    ├── Encrypted AES-128.txt
    ├── Encrypted AES-192.txt
    ├── Encrypted AES-256.txt
    └── Encrypted ZipCrypto.txt
    0 directories, 5 files
    $ md5sum mnt/*
    7a542815e2c51837b3d8a8b2ebf36490  mnt/ClearText.txt
    md5sum: 'mnt/Encrypted AES-128.txt': Input/output error
    md5sum: 'mnt/Encrypted AES-192.txt': Input/output error
    md5sum: 'mnt/Encrypted AES-256.txt': Input/output error
    md5sum: 'mnt/Encrypted ZipCrypto.txt': Input/output error
    $ cat mnt/*
    This is not encrypted.
    cat: 'mnt/Encrypted AES-128.txt': Input/output error
    cat: 'mnt/Encrypted AES-192.txt': Input/output error
    cat: 'mnt/Encrypted AES-256.txt': Input/output error
    cat: 'mnt/Encrypted ZipCrypto.txt': Input/output error

For security reasons, mount-zip doesn’t allow to specify the password on the command line. However, it is possible to pipe the password to mount-zip’s standard input:

    $ echo password | mount-zip different-encryptions.zip mnt
    Need password for File [1] '/Encrypted AES-128.txt'
    Password is Ok

  Symbolic links

mount-zip shows symbolic links recorded in the ZIP archive:

    $ mount-zip symlink.zip mnt
    $ tree mnt
    mnt
    ├── date
    └── symlink -> ../tmp/date

Note that symbolic links can refer to files located outside the mounted ZIP archive. In some circumstances, these links could pose a security risk.

Symbolic links can be suppressed with the -o nosymlinks option:

    $ mount-zip -o nosymlinks symlink.zip mnt
    Skipped Symlink [1] '/symlink'
    2021-10-28 20:05:01 laptop ~/mount-zip/tests/blackbox/data (intrusive)
    $ tree mnt
    mnt
    └── date
    0 directories, 1 file

  Special Files

mount-zip shows special files (sockets, FIFOs or pipes, character and block devices) recorded in the ZIP archive:

    $ mount-zip pkware-specials.zip mnt
    $ ls -n mnt
    brw-rw---- 1    0    6 8, 1 Aug  3  2019 block

    lrwxrwxrwx 1 1000 1000    7 Aug  3  2019 z-hardlink-symlink -> regular

Special files can be suppressed with the -o nospecials option:

    $ mount-zip -o nospecials pkware-specials.zip mnt
    Skipped Block Device [0] '/block'
    Skipped Character Device [1] '/char'
    Skipped Pipe [2] '/fifo'

    lrwxrwxrwx 1 1000 1000  7 Aug 25  2019 symlink2 -> regular
    -rw-r--r-- 3 1000 1000 32 Aug  9  2019 z-hardlink1

    lrwxrwxrwx 1 1000 1000  7 Aug  3  2019 z-hardlink-symlink -> regular

  Hard Links

mount-zip shows hard links recorded in the ZIP archive.

In this example, the three file entries 0regular, hlink1 and hlink2 point to the same inode number (2) and their reference count is 3:

    $ mount-zip -o use_ino hlink-chain.zip mnt
    $ ls -ni mnt
    2 -rw-r----- 3 0 0 10 Aug 14  2019 0regular
    2 -rw-r----- 3 0 0 10 Aug 14  2019 hlink1
    2 -rw-r----- 3 0 0 10 Aug 14  2019 hlink2
    $ md5sum mnt/*
    e09c80c42fda55f9d992e59ca6b3307d  mnt/0regular
    e09c80c42fda55f9d992e59ca6b3307d  mnt/hlink1
    e09c80c42fda55f9d992e59ca6b3307d  mnt/hlink2

Some tools can use the inode number to detect duplicated hard links. In this example, du only counts the size of the inode (2) once, even though there are three file entries pointing to it, and only reports 10 bytes instead of 30 bytes:

    $ du -b mnt
    10      mnt

Duplicated hard links can be suppressed with the -o nohardlinks option:

    $ mount-zip -o nohardlinks hlink-chain.zip mnt
    Skipped File [1]: Hardlinks are ignored
    Skipped File [2]: Hardlinks are ignored
    $ ls -ni mnt
    2 -rw-r----- 1 0 0 10 Aug 14  2019 0regular

  File Permissions

mount-zip shows the Unix file permissions and ownership (UIDs and GIDs) as recorded in the ZIP archive:

    $ mount-zip unix-perm.zip mnt
    $ ls -n mnt
    -rw-r----- 1 1000 1000 0 Jan  5  2014 640
    -rw-r---w- 1 1000 1000 0 Jan  5  2014 642
    -rw-rw-rw- 1 1000 1000 0 Jan  5  2014 666
    -rwsrwsr-x 1 1000 1000 0 Jan  5  2014 6775
    -rwxrwxrwx 1 1000 1000 0 Jan  5  2014 777

Note that these access permissions are not enforced by default. In this example, I am able to read the file 640 even though I don’t own it and I don’t have the read permission:

    $ md5sum mnt/*
    d41d8cd98f00b204e9800998ecf8427e  mnt/640
    d41d8cd98f00b204e9800998ecf8427e  mnt/642
    d41d8cd98f00b204e9800998ecf8427e  mnt/666
    d41d8cd98f00b204e9800998ecf8427e  mnt/6775
    d41d8cd98f00b204e9800998ecf8427e  mnt/777

To enforce the access permission check, use the -o default_permissions mount option:

    $ mount-zip -o default_permissions unix-perm.zip mnt
    $ md5sum mnt/*
    md5sum: mnt/640: Permission denied
    md5sum: mnt/642: Permission denied
    d41d8cd98f00b204e9800998ecf8427e  mnt/666
    d41d8cd98f00b204e9800998ecf8427e  mnt/6775
    d41d8cd98f00b204e9800998ecf8427e  mnt/777

  Absolute and Parent-Relative Paths

mount-zip supports absolute and parent-relative paths in file names. Absolute paths are displayed under the ROOT directory. For parent-relative paths, every .. is replaced by UP. Finally, ordinary relative paths are placed under the CUR directory:

    $ unzip -l mixed-paths.zip
     Length      Date    Time   Name
    --------  ---------- -----  ----
          49  2021-11-02 13:55  normal.txt
          29  2021-11-02 13:55  ../up-1.txt
          30  2021-11-02 13:55  ../../up-2.txt
          40  2021-11-02 13:55  /top.txt
          45  2021-11-02 13:55  /../over-the-top.txt
    --------                    -------

  Smart Caching

mount-zip only does the minimum amount of work required to serve the requested data. When reading a compressed file, mount-zip only decompresses enough data to serve the reading application. This is called lazy or on-the-go decompression.

Accessing the beginning of a big compressed file is therefore instantaneous:

    $ mount-zip 'Big One.zip' mnt
    $ ls -lh mnt/
    -rw-rw-r-- 1 root root 6.4G Mar 26  2020 'Big One.txt'
    $ time head -4 'mnt/Big One.txt'
    We're going on a bear hunt.
    We're going to catch a big one.
    What a beautiful day!
    We're not scared.
    real    0m0.030s
    user    0m0.015s
    sys     0m0.014s

mount-zip generally avoids caching decompressed data. If you read a compressed file several times, it is getting decompressed each time:

    $ dd if='mnt/Big One.txt' of=/dev/null status=progress
    6777995272 bytes (6.8 GB, 6.3 GiB) copied, 24.9395 s, 272 MB/s
    $ dd if='mnt/Big One.txt' of=/dev/null status=progress
    6777995272 bytes (6.8 GB, 6.3 GiB) copied, 24.961 s, 272 MB/s

But mount-zip will start caching a file if it detects that this file is getting read in a non-sequential way (ie the reading application starts jumping to different positions of the file).

For example, tail jumps to the end of the file. The first time this happens, mount-zip decompresses the whole file and caches the decompressed data (in about 13 seconds in this instance):

    $ time tail -1 'mnt/Big One.txt'
    The End
    real    0m12.631s
    user    0m0.024s
    sys     0m0.656s

A subsequent call to tail is instantaneous, because mount-zip has now cached the decompressed data:

    $ time tail -1 'mnt/Big One.txt'
    The End
    real    0m0.032s
    user    0m0.018s
    sys     0m0.018s

Decompressed data is cached in a temporary file located in the cache directory ($TMPDIR or /tmp by default). The cache directory can be changed with the --cache=DIR option. The cache file is only created if necessary, and automatically deleted when the ZIP is unmounted.

Alternatively, the --memcache option caches the decompressed data in memory. Be cautious with this option since it can cause mount-zip to use a lot of memory.

You can preemtively cache data at mount time by using the --precache option. The cost of decompression in incurred upfront, and this ensures that any subsequent access to the mounted data is fast.

If mount-zip cannot create and expand the cache file, or if it was passed the --nocache option, it will do its best using a small rolling buffer in memory. However, some data access patterns might then result in poor performance, especially if mount-zip has to repeatedly extract the same file.

PERFORMANCE

On small archives mount-zip has the same performance as commonly used virtual filesystems such as KIO, Gnome GVFS, mc vfs, unpackfs, avfs and fuse-zip. But on large archives containing many files, mount-zip is pretty quick.

For example on my laptop, a ZIP archive containing more than 70,000 files is mounted in half a second:

    $ ls -lh linux-5.14.15.zip
    -rw-r--r-- 1 fdegros primarygroup 231M Oct 28 15:48 linux-5.14.15.zip
    $ time mount-zip linux-5.14.15.zip mnt
    real    0m0.561s
    user    0m0.344s
    sys     0m0.212s
    $ tree mnt
    mnt
    └── linux-5.14.15
        ├── arch
    ...
    4817 directories, 72539 files
    $ du -sh mnt
    1.1G    mnt

The full contents of this mounted ZIP, totalling 1.1 GB, can be extracted with cp -R in 14 seconds:

    $ time cp -R mnt out
    real    0m13.810s
    user    0m0.605s
    sys     0m5.356s

For comparison, unzip extracts the contents of the same ZIP in 8.5 seconds:

    $ time unzip -q -d out linux-5.14.15.zip
    real    0m8.411s
    user    0m6.067s
    sys     0m2.270s

Mounting an 8-GB ZIP containing only a few files is instantaneous:

    $ ls -lh bru.zip
    -rw-r----- 1 fdegros primarygroup 7.9G Sep  2 22:37 bru.zip
    $ time mount-zip bru.zip mnt
    real    0m0.033s
    user    0m0.018s
    sys     0m0.011s
    $ tree -h mnt
    mnt
    ├── [2.0M]  bios
    ├── [ 25G]  disk
    └── [ 64M]  tools
    0 directories, 3 files

Decompressing and reading the 25-GB file from this mounted ZIP takes less than two minutes:

    $ dd if=mnt/disk of=/dev/null status=progress
    26843545600 bytes (27 GB, 25 GiB) copied, 104.586 s, 257 MB/s

There is no lag when opening and reading the file, and only a moderate amount of memory is used. The file is getting lazily decompressed by mount-zip as it is getting read by the dd program.

LOG MESSAGES

mount-zip records log messages into /var/log/user.log. They can help troubleshooting issues, especially if you are facing I/O errors when reading files from the mounted ZIP.

To read mount-zip’s log messages:

    $ grep mount-zip /var/log/user.log | less -S

To follow mount-zip’s log messages as they are being written:

    $ tail -F /var/log/user.log | grep mount-zip

Alternatively, you can run mount-zip in foreground mode with the -f option and read all the log messages on the terminal.

By default, mount-zip writes INFO and ERROR messages. You can decrease the logging level to just ERROR messages with the --quiet option. Or you can increase the logging level to include DEBUG messages with the --verbose option:

    $ mount-zip -f --verbose foobar.zip mnt
    Indexing 'foobar.zip'...
    Allocating 16 buckets
    Detected encoding UTF-8 with 15% confidence
    Indexed 'foobar.zip' in 0 ms
    Mounted 'foobar.zip' on 'mnt' in 2 ms
    Reader 1: Opened File [0]
    Reader 1: Closed
    Unmounting 'foobar.zip' from 'mnt'...
    Unmounted 'foobar.zip' in 0 ms

To prevent file names from being recorded in mount-zip’s log messages, use the --redact option:

    $ mount-zip -f --verbose --redact bad-crc.zip mnt
    Indexing (redacted)...
    Allocating 16 buckets
    Indexed (redacted) in 0 ms
    Mounted (redacted) on (redacted) in 2 ms
    Reader 1: Opened File [0]
    Cannot read (redacted): Cannot read file: CRC error
    Reader 1: Closed
    Unmounting (redacted) from (redacted)...
    Unmounted (redacted) in 0 ms

RETURN VALUE

mount-zip returns distinct error codes for different error conditions related the ZIP archive itself:

0   Success.

1   Generic error code for: missing argument, unknown option, unknown file name encoding, mount point cannot be created, mount point is not empty, etc.

11  The archive is a multipart ZIP.

15  mount-zip cannot read the ZIP archive.

19  mount-zip cannot find the ZIP archive.

21  mount-zip cannot open the ZIP archive.

23  Zlib data error. This is probably the sign of a wrong password. Use --force to bypass the password verification.

26  Unsupported compression method. Use --force to bypass the compression method verification.

29  The archive is not recognized as a valid ZIP.

31  The ZIP archive has an inconsistent structure.

34  Unsupported encryption method. Use --force to bypass the encryption method verification.

36  Needs password. The ZIP archive contains an encrypted file, but no password was provided. Use --force to bypass the password verification.

37  Wrong password. The ZIP archive contains an encrypted file, and the provided password does not allow to decrypt it. Use --force to bypass the password verification.

45  Possibly truncated or corrupted ZIP archive.

PROJECT HISTORY

mount-zip started as a fork of fuse-zip.

The original fuse-zip project was created in 2008 by Alexander Galanin (http://galanin.nnov.ru/~al/) and is available on Bitbucket (https://bitbucket.org/agalanin/fuse-zip).

The mount-zip project was then forked from fuse-zip in 2021 and further developed by François Degros (https://github.com/fdegros). The ability to write and modify ZIP archives has been removed, but a number of optimisations and features have been added:
