If you frequently download files, this small but powerful tool is great for verifying that those files are valid and uncorrupted. The presence of QuickSFV is evidenced only by a small desktop icon shaped like a lifesaver. You use this tool by first clicking on a download's verification file in Windows Explorer. QuickSFV quickly runs a check on the download files, comparing them to the checksum values stored in the verification file to determine if the downloads are valid and not corrupted during the download process. A display box opens and lists each file in the download packet as it's checked, and QuickSFV then notes whether there are corrupt files and names them, if there are any. This tool works with a variety of verification file formats, including SFV, MD5, CRC, and PAR. You also can use QuickSFV to create an accurate verification file for your own download packets. Anyone who depends on frequent or large downloads will find QuickSFV a reliable addition to his or her PC toolbox.
