It is sad to getting bad files when you download many large files from the server, and after some hours, you want to use these files or decompress them. Is there a way to avoiding that? Sure! That's what FTP Rush client SFV checker does.
The SFV checker is very fast and checking the integrity of your download remote files in the background. After one remote file downloaded, the checker searches the SFV file inside the same directory and notices you of any bad, good, or missing files, and It also has an option for you to download the remote file again if found it is corrupt.
