This utility checks the validity of downloaded files by quickly comparing the files to a previously generated checksum. With HkSFV's simple two-pane interface, you can easily browse for files or folders to validate. Using HkSFV is merely a matter of pointing the program to the SFV (simple file verification) file of your download. The SFV lists the checksums of each file in the download. Many program authors use SFV files to help recipients ensure they're getting the correct files. HkSFV computes the checksum for each file exceedingly fast and compares that number to the expected checksum. Simplicity is one of the better features of this application, as all checked files are clearly identified as OK, bad, or not found. HkSFV also works in reverse and quickly generates SFV files for a folder or compressed file. In our tests, HkSFV only once tagged as OK an invalid compressed file. Programmers who need to create SFV files and any level of user who downloads from services that include checksum files will want this freeware application.
