change in UAL e-timetable software (windows version) shrinking
 

For those who use the windows version of UAL electronic timetable - it seems like every update of the schedule adds a new E11924.exe and E11924.htm (numbers purely for illustrative purposes only) file to the UAL E-timetable folder. When is it safe to delete these files? It seems highly in-efficient to leave these crumbs on your hard drive, especially when the .exe file is over 2.5 MB's.

Note: It seems after the 8/5/02 update, the E180304.exe and subsequent files have shrunk from 4.5 MB to around 2.8 MB's. Does this suggest a tremendous reduction in the number of flights, thus a smaller update file?

The E*.htm and E*.exe files seem to be entirely superfluous. Whenever I happen to think of it, I delete those accumulated files, and my deletions don't seem to do any harm. The electronic timetable continues to work fine even after my deletions.

In my opinion, it's ridiculous that the electronic timetable program leaves this useless clutter on my hard drive every time I do a timetable update.

Not only that, but it also cannot find the original installation and always reverts back to the C-drive. Plus it keeps asking for my company name...
