Hi hewee,
The reason I posted this thread was merely informational, as everytime I ran it, it would take a long time to run by searching the C:\ drive. I have the Java JDK kit installed and the scan time increases way too much. I sent a comment to the authors of Index.dat Suite and they replied with the information in my first post that didn't seem to be well documented.
One good reason to run this tool vs say using DOS with a delete command to remove all of the index.dat files from you system is that the delete command will also remove a required index.dat file in WinXP in the C:\WINDOWS\pchealth\helpctr\OfflineCache folder path which if missing will cause both System Information and Help and Support Center to malfunction.
Index.dat Suite highlights that particular index.dat file in red and does not automatically check it for deletion.
The folks that created Index.dat Suite probably understand index.dat files better than anyone writing a tool to delete them out there.
Your advice is sound, but this tool happens to be what I consider the best at dealing with index.dat files.
For a good article, read * The truth about the index.dat files: What, why and where? by Steven Burn
