#21 Make screencast using Jing capture

MD5 checksum is used mainly to verify the integrity of files in transit. It uniquely identifies a file like its fingerprint. Suppose you downloaded a file and its MD5 signature is also known, you can ensure that the downloaded file has not been tampered with by regenerating its MD5 checksum and compare it with the original known value.
The accompany Jing file shows how to create the checksum using a freeware called FreeCommander.
1. Invoke FreeCommander.
2. Select the target file.
3. File -> Create MD-5 checksum -> Ok
