Decompresses a file.
This function uses gzip file format, so please use file extension .gz.
As this function processes file in chunks it should work fine with huge files.
In case of an error like a full hard disk, you need to manually delete the half written output file.

This function requires a native path. Use Path.FileMakerPathToNativePath to convert a FileMaker path to a native path if required. If you like to have the user choose the path, you can use FileDialog functions.
For Server be aware that server has limited permissions and may not be able to access all files on a computer.


Uncompress a file:

MBS( "GZipFile.Decompress"; "C:\test.gz"; "C:\test.txt" )
