They can verify existing checksums or Create new checksum for your important data. Summarizing, it's not necessary to verify checksums (I've never done it), but it doesn't hurt if you have the time.Editor: EF CheckSum Manager is a program designed for the integrity examination of files on the standard formats SFV, MD5 and SHA1.

If you know the supposed checksum of a file, and you download another file that doesn't match this checksum, you either have a file with errors (see above), or somebody wants to trick you. This could be due to a single bit error that occured during the download. During setup, the installer notices that there is a broken file on the disk.
