I noticed that the button "Create New", does not work, no Archive is generated.
For example I tried to enter the "lha a" command in the config, it works, but it compresses the ZuneARC folder, and not the path chosen in the request file, is there a "parameter" to add in the config to let ZuneARC know which path to compress?

I am reconfiguring ZuneARC so that it uses the XAD library, and it seems to work very well

Ok found out how "Create New" works, reading info on aminet that "Create New" can only generate an "empty" archive.
To create an archive of files, you must then use the "Add File" button and insert the chosen files or folders, once this is done the new archive will be generated and saved in the chosen location

You will probably be able to do this for all formats that allow you to add files, same for 'Remove/Extract Selected' .
