QuickSFV v3.00 Beta

QuickSFV is a fast -- and free -- file verification program that supports file verification based on .sfv, .md5, .crc, .par and variety of other formats.

File verification tools like QuickSFV are meant for checking whether a downloaded or otherwise transferred files are valid and haven't corrupted when they have been transferred (for example, by downloading over unreliable Net connections).

Basically how the verification software is commonly used is that with file downloads, like from FTP sites, the main download file or files are in one folder, often named as file.rar, file.r01, file.r02, etc. In addition of those files, the same folder contains also one verification file, like file.sfv. After all the files have been downloaded, double-clicking the file.sfv file will launch QuickSFV that will then compare the downloaded files to the checksum values stored in the .sfv file and will tell whether the files are complete and valid or not. In case the download contained several files, it indicates which files are corrupt and need to be re-downloaded.

QuickSFV can be also used to create checksum files, such as .sfv files, out of binary and text files, which makes it excellent tool for creating secure download packages for FTP sites, websites, etc.
