In depth
A closer look at Filename Randomizer
Filename Randomizer is a lightweight and portable software application whose only goal is to randomize the file names of a user-selected directory. It does not include complicated settings, so the program can be handled with confidence even by people with no background in software utilities.Since installation is not a prerequisite, you can drop the executable file in a custom location on the hard disk and just click it to run.There is also the possibility of saving Filename Randomizer to a USB flash disk or similar storage unit, in order to run it on any PC with minimum effort, as long as it has .NET Framework installed.Note that the device must not be write-protected, since an INI file with the program's configuration is automatically created in the same location at startup.An important aspect to take into account is that the Windows registry does not get updated with new entries, and no extra files are created on the HDD without the user's approval.The interface is based on a small window with a simple layout and only two buttons. You can use the folder view to point out the target directory, since the drag-and-drop support is not featured. Renaming all containing files is done with the simple click of a button, and changes are immediately committed. In addition, you can mark the items as hidden. There are no other notable options provided by this utility.As expected, Filename Randomizer has minimal impact on computer performance, using low CPU and memory. We have not experienced any difficulties in our evaluation, as the program did not freeze, crash or pop up error dialogs. All in all, Filename Randomizer serves its purpose and, thanks to its overall simplicity, it can be used by anyone.
