I recently received an email from Jim Lawler, the programmer behind PurgeIE:
I am the author of PurgeIE which you reviewed for one of your newsletter articles.
Please take a look at “DelinvFile” and consider mentioning it in your “Tips…” section.
Although I recently converted “DelinvFile to a commercial version, the basic functionality is available without having to register (pay a fee).
The webpage is – http://www.purgeie.com/delinv/index.htm
Basically, “DelinvFile” is an easy-to-use utility that one can use to delete data files that they are not able to delete with the normal Windows Delete function.
