[Ham-Computers] DOS Trick

[Trevor Holyoak]

You can actually do this much easier from Windows, just do a search in 
Windows Explorer. Then you can just select any files that show up on the 
resulting list and hit the "delete" key.

You may find leftover files (program fragments) but not _file_ 
fragments. There are actually file fragments all over your hard drive, 
but they are ignored. To make it fairly simple,
when you delete a file, it's actually just marked as deleted, and the 
next info is written to the disk, it can write over portions as it needs 
to. Once a file is marked as deleted, though, it will no longer show up 
in a directory search.

The reason you may find leftover files after a program has been 
uninstalled is that often a program puts files in more than one 
directory, and the uninstall program doesn't always delete them all. 
This may be because it's assumed you may want files you created with the 
program (probably a valid assumption), or because it's possible that 
another program is using one of the files, or because Windows still has 
a lock on one or more files, or it might just simply be lazy 
programming. (I'm actually amazed every time I write an uninstall script 
that actually successfully removes all traces of the program - Windows 
often keeps locks on things that make that impossible.)
