Multiple files can be added. Files ending in ".zip" will be searched for 'xl.meta' files.
Wildcards are accepted: testdir/*.txt will compress all files in testdir ending with .txt
Directories can be wildcards as well. testdir/*/*.txt will match testdir/subdir/b.txt
Double stars means full recursive. testdir/**/xl.meta will search for all xl.meta recursively.
