XGman, nice app - however I've had some issues with it.
1) I've had trouble with at least one ISO (I've only used it to move 2 ISO's over so far) where it gave me an error message stating it couldnt copy the file over. Extracted with XISO and FTP = no problem. There was lots of space on the drive, and my temp file area as well.
2) After moving a ~3GB ISO across (second attempt), it would not refresh properly. It automatically updates, but the progress stuck in the middle and the new folder did not show. Hit update button, but nothing seemed to happen. Killed the prog and re-ran it, seemed to be fine.
3) Slooooow for updating typically. And it seems to move a large amount of data when updating (according to my bandwidth meter). I have a 110GB partition with ~20GB worth of stuff.
Other than that, it seems fine. Good job!
