Portable CheckFolder

Created as the portable edition of CheckFolder, this is a simplistic tool that can scan entire directories to verify whether the containing files are corrupt or not.

You can use it to check the integrity of files before burning them to disk, for example, to make sure everything is in working order. Although it may sound complex, the program performs scan jobs automatically and sports just a couple of configuration settings.

Since there is no setup pack involved, you can extract the application files to any directory on the disk and just click the .exe to launch CheckFolder. There is also the possibility to store it on a removable storage unit (like a pen drive) to effortlessly run it on any PC and verify file integrity. Unlike most installers, it doesn't modify Windows registry settings.

Represented by a plain and simple window, the interface lets you get started by selecting a drive or directory whose containing files you want to check for errors.

This task can be triggered with the click of a button, after which CheckFolder shows two progress bars for the current file and overall task. Plus, you can check out the elapsed, remaining and total time, processed files and folders, together with identified errors (if any).

Unfortunately, the app doesn't implement an option for opening the location of the faulty files in Windows Explorer without leaving CheckFolder's interface, nor for eliminating them from the disk or at least moving them to a separate folder.

On the other hand, it has some buttons with shortcuts to quickly scan the removable and optical drives, while new ones can be added to the list with any drive or directory you want. You can also change the interface skin, set the buffer size (in bytes), and control errors by preventing denied access or sharing violations.

The tool didn't put a strain on the overall performance of the machine in our tests. It carried out scan jobs swiftly and didn't hang, crash or prompt errors. Although it doesn't come bundled with more advanced options and configuration settings, CheckFolder can be handled by less experienced users who want to rapidly check files for errors.
