I use linux both at the office and on my servers, and I have no trouble opening 50GB tarballs. If you're going to open them on Windows I really don't know if winzip or any of the other similar programs will open a 50 GB file.but what was the max size of a file that you open? I just test it with a 2gb file and did not had any issue to open it, but I am curious to know if with files like 50gb if it will open
