Story Topic:


There must be an option to download the beta version of 7-zip because I have a problem with my backups...

Toucan uses the beta version of 7zip so when I backup my flash drive then I want to extract the .7z file using 7zip portable it says "Unknown compression method" maybe because toucan used the new lzma2 compression method.
