I'm not sure whether this is a problem of TotalCommander or Windows (it's Win 8.0 here), but I have encountered a minor problem that didn't show a proper explanation in TotalCommander.
It was only today that I found out, after many months of confusion, why I was unable to delete some files and folders from my 3TB USB drive. The reason was that it was formated as FAT32 (which I knew), and as such couldn't handle files greater than 4gb (which I knew). The thing I hadn't expected was that you cannot delete several files with a sum of more than 4gb at a time (the bar seems to be 4.200gb, to be precise). Unfortunately, TotalCommander also does not state this issue, and I wonder why this problem even exists. Shouldn't TotalCommander be able to delete the files in a consecutive way rather than all of them together?
I'm glad I finally found this out and I'm curious what you say about it

Best,
Achim
