|I don't know the reason for this and doubt anyone else will. This is because you are working in an area where MS shows you "what it thinks you would like to see", in conjunction with registry entries. If you look in that same place with a Linux Live CD |
(no Windows running) you will find it is not the same. Viewed from within Windows XP the inner duplicated TIF folder is abnormal.
It follows that it is not a place where you can just delete folders in the normal way and expect to predict the results. Windows has now got a tad screwed and now (wrongly) sees these duplicated TIF folders as correct.
Have you tried CCleaner freebie to see if that sorts it out? Long shot but it does clear TIF's and reconstruct the Index.dat file.
Creating a new account is another possible way forward, but has drawbacks.
If you can do a System Restore to a time before you worked on it, that would be the best and safest bet.
If you like tinkering then maybe moving the TIF folder from within IE might sort it out, possibly deleting the inner folder first. Go to IE > Tools > Internet Options > Settings button (in Browsing history area) > Move folder button. It might not work but letting Windows do as much as possible has the best chance, because in this area things are not as straightforward as they might appear to be.

Always pop back and let us know the outcome - thanks
