RebateMonger,
Thanks for the reply. You are right of course -- I did not wish to delete every ico file on the C drive, just the 43,000 plus that Icon Searcher put there. Since I hadn't rebooted since they were put there, they were all appended to the list of files and folders I had before this happened. I decided to try the nearly manual way of removing them -- click on one, hold down shift and move to the end of the list and click to select them all, and then do a delete. This would not work because of the sheer number, but I found I could do it for about 10,000 at a time. Took about ten minutes before the click on the last file (of the block) could be entered, and then several minutes after the right click before the menu appeared for the delete. The delete for each block then took over fifteen minutes each, but eventually after over two hours of effort, they are all removed. That is more effort than any piece of software deserves.
I appreciate the assistance -- from a fellow Elite Member. I think we are not too many in number.
