Dr Delete

Dr Delete is a small-sized and portable tool capable of eliminating stubborn files that cannot be deleted under normal circumstances, such as Index.dat items and DLLs. It is very simple to use.
As there is no setup pack involved, you can save the executable file anywhere on the disk and click it to run. Plus, you can move Dr Delete to a USB flash disk or similar storage unit, in order to run it on any workstation effortlessly, without prior installers.
What's more, the Windows registry does not get new entries, and leftovers do not remain on the hard drive after removing the program. A standard file deletion is enough to accomplish this goal.
The interface is made from a common screen, where you can schedule a file to be deleted at the next system startup (even an application that's currently in use), by using the file browser to locate and select it.
If the respective file can be deleted without a restart, Dr Delete takes care of the job right away. There are no other options available through this tool.
As we have expected, Dr Delete has a minimal impact on computer performance, as it uses a very low quantity of CPU and RAM. No error dialogs have been shown in our tests, and the utility did not hang or crash. Too bad it has not been updated for a very long time. Otherwise, Dr Delete should please all types of users, regardless of their computer skills.
