Thumbnail Database Cleaner

Thumbnail Database Cleaner is a small-sized and portable software utility that enables you to clean the thumbnail cache, as its name hints at.
It does not include complicated options or configuration parameters, so it can be handled by all user categories.
Since installation is not a prerequisite, you can drop the executable file anywhere on the hard disk and just click it to run.
An alternative is to save Thumbnail Database Cleaner to a USB flash disk or other mass storage device, to be able to run it on any PC effortlessly, as long as it has .NET Framework installed.
In addition, the tool does not create new entries in the Windows registry or Start menu, leaving no traces behind after removing it.
A regular window with an intuitive layout puts together the interface. All you have to do is point out a directory or entire drive to look into, include subdirectories, and click a button to start the scanning procedure.
It does not take a long time to finish, depending on the size of the selected location. Results show the dimension, date and full path for each identified file. Once you handpick the exact items you want to remove (select-all and deselect-all buttons are available), Thumbnail Database Cleaner takes care of the cleaning process. There are no other notable options available here.
The tool is very fast when it comes to scanning and cleaning. It has minimal impact on performance, as it uses low CPU and RAM. We have not come across any kind of issues throughout our evaluation, as Thumbnail Database Cleaner did not hang, crash or pop up error dialogs. Thanks to its overall simplicity, it can be figured out quickly by anyone.
