MD5 checker

MD5 checker is a feather-light and portable utility that gives you the possibility to put together MD5 files with the MD5 signatures of one or multiple files at a time, as well as to check and compare hashes.

The entire program's packed in just one .exe file that you can copy to a preferred directory on the disk or to a removable storage unit to directly run it on any PC. It doesn't need DLLs to run, create files on the disk without your permission, or add new entries to the system registry.

It's wrapped in a user-friendly interface, where the main window is split into three areas for separately creating, verifying and comparing checksums.

In order to create MD5 files, you can add one or more files to the task list with the aid of the file browser. It's also possible to indicate a folder whose entire containing files you want to process, while including or excluding subfolders.

MD5 checker shows the name, source folder and MD5 hash of each file, and it can save all this information to an .md5-formatted file in the same directory after you enter the file name.

If you want to find out if the MD5 checksums of files match the ones included in the .md5-formatted file, all you have to do is indicate the .md5 file after making sure that the corresponding items exist in the same directory. The software utility shows the name and full path of each file, along with the original and existing MD5 hashes. It also counts the matches and errors.

Comparison tasks can be performed by pointing out a file and pasting an MD5 hash to find out if they match or not.

To wrap it up, MD5 checker offers a simple solution for calculating, checking and comparing MD5 hashes, as well as for creating MD5 files. System resources usage was low in our tests.
