I discovered it accidently by creating multipart RAR archive splitting it to 4GB parts so that they can be copied to FAT32 partitions and found that TC doesn't display the file size at all
I'm using Full View and instead of showing that the files xxx.rar, xxx.r00 etc. are of 4GB-1B (4.294.967.295 Bytes exactly) size, it shows only a single questionmark. When selected TC shows something like "0 k / xx.xxx.xxx k in 1 / xxx files, 0 / xx dir(s)" at the bottom of the left/right pane.
The "Calculate Occupied Space.." option works fine and shows the correct file size. Then I tried the "Synchronize Dirs..." command and it works fine too showing the correct file sizes. Everything else works without any problems (Copy/Move...), so I'm guessing it's something stupid, but could be anoying for somebody
Then I searched for some other big files and found the bigest one, but there was no problem. It's file size is 3.94GB (4.233.252.717 Bytes exactly). I hope this will help you locating the problem...
