There is a way to tell the differnce between incomplete file and completed. If you go to the folder, imcomplete file tend to have humber on the front of the name of the file. completed file have their original file name without a number.

No, the problem was that it displays the files as 100% finished, and would leave them like that for hours, but they would still stay in the incomplete folder with the "T-[Insert Random Numbers Here]" prefix.
