Thunar shows the sizes of folders that contains many GBs as measuring 0,0KB or 4,1KB. Some say it's not a bug, but if it's not a bug, i suggest you to take off the "size" cell because it's useless. I really think that it could show the actual size of every folder by default like it does with files. Thank you.
There are already plans to replace the 4.1KB: https://bugzilla.xfce.org/show_bug.cgi?id=10338 https://bugzilla.xfce.org/show_bug.cgi?id=11524 Both already with working patches ... however both stil lack quality to get pushed to master. *** This bug has been marked as a duplicate of bug 10338 ***
Thank you, alexxcons! I saw the patch but don't know how to patch it. I still hope someday xfce team will do this. Thanks!
