ucc decompress filename.uz is used to decompress a .uz file.
Unfortunately, ucc decompress doesn't support wildcards, so decompressing a complete folder can not be decompressed with "ucc decompress *.uz". That can be very painful if you need to recover your files from a http redirect folder.
A workaround is following:
put this into a batch file (.bat)
for %%f in (*.uz) do ucc decompress %%f
(add specific paths if the .uz files are not in the system folder)
