I want to archive a folder, but I want to exlude all media files.

How do I leave out *.avi and *.flac when archiving?

Only possible solution is to use the command-line version (it doesn't work in the GUI [Add to Archive] dialog):

7z.exe a Archive.7z C:\Folder\* -r -x!*.avi -x!*.flac

The "Parameters" input box in the GUI can only be used for compression parameters and cannot be used with standard command line parameters.

    Note that you might need to add r for recursive so it will be -xr!*.avi

    If you use powershell make sure to wrap it quotes: "-x!*.config" I just lost half an hour over that!

  • Just as reference, this is my batch file to backup my C# projects in folder "C:\prj": "C:Program Files\7-Zip\7z.exe" a prj.7z "C:\prj*" -r -x!*.tmp -x!*.pdb -x!*.exe -x!*.dll pause Jun 14, 2016 at 2:01

    Interestingly enough, -r in my case was needed so that the extensions were actually excluded, but did recurse subdirectories with or without -r

    @Clement in case of powerShell single quotes should be used. PS has ignored -x switch in double quotes like you said. & $a7z a $archName $binpath $addfiles -m0=LZMA '-xr!*.config' '-xr!*.log' works like a charm for me

7za -bt -mx9 a archive.7z d:\backups\*  -x!*.7z


7za -bt -mx9 a archive.7z d:\backups\*.*  -x!*.7z

Created different result. The one with *.* seem to work.
