RekSFV is a free program for Windows that is available as a portable version and installer that verifies files in bulk using existing sfv, md5 and sha1 information.
The program ships with options to create sfv, md5 or sha1 verification files. To do that, simply click on one of the available icons in the main program window and add one or multiple folders to the prompt that opens up to create verification files.
Please note that the program threw out of memory errors during sfv file generation while the generation of md5 files completed without issues.
File verification is useful in several situations, for instance to make sure that backups are not corrupt, that file downloads completed without transfer errors, or that important system files have not been tampered with.
To verify files, drag and drop a folder into the program interface containing at least one of the supported checksum files.
The program parses the folder structure recursively, checks for verification files, and uses the information in those files to verify the files referenced.
The check itself is fast and progress is displayed as a log output directly in the interface while checks are still being made.
The program highlights errors with a red background color so that you know immediately if files did not verify and the reason why.
First thing you may want to do if errors are found during a scan is to switch to the bad & missing file(s) tab. The tab lists all files with errors in the interface including the full file path, extension, reason why the check failed and the expected checksum.
A toolbar at the top and the right-click menu display several options to process these files. You may run a scan to find the missing files, delete all bad files or folder, move the folder with bad or missing files, or save the list to the clipboard.
One useful application of the program is to use it to verify backups. You generate checksums of files that you have backed up first, and verify the integrity of those backups later on then regularly to make sure that they are not corrupt and can be restored without issues.
RekSVF offers lots of customization options in the program settings. Use the settings to modify program behavior, define which information are displayed to you in the interface, or whether hidden files or folders should be added to the checksum file.
RekSFV supports the creation of checksum files and the verification of these files. While you can install it, you may also use the portable version of the program, for instance to verify files on discs or Flash drives regularly.Advertisement
