I'm using an 8GB RAMdisk (using ImDisk) to temporarily save the files from TS-Doctor for further processing. My source files are usually about 18GB and the cut files are always well under 8GB. When I click "Save new file" I get a warning that there is not enough disk space, but this is incorrect and obviously based on the source file size rather than the new file size. It would be good if TSD actually estimated the filesize. :D
