MD5 checksum is a cryptographic hash function that generates a unique value for a given file or data. The checksum can be used to verify the integrity of the file, i.e., to ensure that the file has not been corrupted or tampered with during transmission or storage. In this guide, we will show you how to check and verify the integrity of a file using MD5 checksum on Windows 7.
Step 1: Download and Install MD5 Checksum Tool
To check the MD5 checksum on Windows 7, you will need to download and install an MD5 checksum tool. One such tool is WinMD5Free, which is a free and open-source software. You can download it from the following link: https://www.winmd5.com/
After downloading the software, install it on your Windows 7 computer by running the setup file and following the on-screen instructions.
Step 2: Calculate the MD5 Checksum
Next, you need to calculate the MD5 checksum of the file you want to verify. To do this, open the WinMD5Free tool and click on the “Browse” button to select the file.
Once you have selected the file, click on the “Calculate” button to generate the MD5 checksum. The checksum value will be displayed in the “MD5” field.
Step 3: Compare the Checksum Values
Now, you need to compare the calculated checksum value with the original checksum value provided by the file source or sender. If the checksum values match, the file is intact and has not been modified during transmission or storage.
To compare the values, copy the original checksum value provided by the source or sender and paste it in the “Compare” field of the WinMD5Free tool. Then, click on the “Compare” button.
If the values match, you will see a message that says “Checksums Match!”. If the values do not match, you will see a message that says “Checksums Do Not Match!”.
