# TGZFileStream.create

Create a new instance of TGZFileStream

## Declaration

Source position: zstream.pp line 93

`public constructor TGZFileStream.create(`
`filename: ansistring;`
`filemode: Tgzopenmode`
`);`

## Arguments

`filename` |  | Name of the gzip file
`filemode` |  | Open mode for the file.

## Description

Create creates a new instance of the TGZFileStream class. It opens FileName for reading or writing, depending on the FileMode parameter. It is not possible to open the file read-write. If the file is opened for reading, it must exist.

If the file is opened for reading, the TGZFileStream.Read method can be used for reading the data in uncompressed form.

If the file is opened for writing, any data written using the TGZFileStream.Write method will be stored in the file in compressed (deflated) form.

## Errors

If the file is not found, an EZlibError exception is raised.
