I've just spent a long time using dTa to get some cab files for Vanguard SoH. After 4 Gb (2 cab files) has completed I check the final location only to find that the files aren't there.
I then check the temp location for downloading partfiles, I have 4 gig of part files which between them comprise 2 complete cab files - but how can I tell which part files belong to which cab file - there is no pattern in the naming of the part files.
Can I suggest that you include the original name in the part files? Something like dtatempfile-for-<filename>-###########.part# - this way it would be trivial to take all the part files that belong to one final file and recreate the final file.
Since I've wasted the better part of 2 days waiting for my download to complete, you can imagine exactly what I think of you right now - the part file rename is something so trivial I hope it makes it into the next point release.
