I am attempting to back up my PhD onto Pelican. One of the constraints of Pelican is not having lots of little files so I want to Zip up my files before I transfer them. Unfortunately WinZip (on the PWF) keeps crashing when I try to do this. After it has been transferring the data it says:

Could not replace original Zip file! New Zip left as U:\Backups\WZ128E.tmp.
Ok Help

When I click ok it asks whether I want to see the log file. This tells me the last file successfully ends:

Adding MyTex/GwedyYnol/GwedyYnolDiagramho.eps
Adding MyTex/GwedyYnol/
copying Zip file
Warning: replace: could not rename U:\Backups\WZ138E.tmp
Could not replace original Zip file! New Zip left as U:\Backups\WZ138E.tmp

Why? After this had happened last time I tried backing up, I noticed that my quote was at 93% and I wondered if this was related, but I deleted some stuff (mainly it has to be said the .tmp files which had been created by those unsuccessful attempts and before the last attempt I was at 48% of quota (so around 125MB free). Now I'm at 56% because of the .tmp file.

What should I do?
