Some programs that use IE libraries for display create temporary files in the TIF folder. IE8's 'Delete browsing history' did not remove these files, but this was corrected in IE9. IE10 10.0.9200.16521 behaves in the same way as IE8 in this respect.
This is a major problem for users of Windows Live Mail and other programs that behave in the same way. There are cases of the program ceasing to work properly, in particular not being able to display messages. Troubleshooting has revealed in some cases that the TIF folder has grown to 7GB containing up to 500,000 files.
