The file .sfv It is a simple text file, the CRC32 algorithm using a simple file detection function calculates the value for each file and a text file written in a .sfv.

After downloading the general purpose tool SFV For the downloaded file, the results are calculated and for file comparison, if the file downloaded from a different program is incorrect, you need to download it again.

And with a specific program to calculate a checksum or batch file, size, date and retention.

CRC32: CRC itself is a means of “redundancy check”. CRC32 generates a 32-bit checksum (8-digit hexadecimal numbers).

Since the CRC32 check value is generated for each bit of the source data block, the bits involved in the calculation will give different CRC32 values.

MD5: Name of one of the message digest algorithms (also called one-way hash function). A 32-bit hexadecimal, of which through a certain algorithm, according to each bit to finally produce a 128 (bit) data source verification value.

The most common application is MD5 cryptography, which is mainly used by paper to verify file integrity; if you find it difficult to understand the character, you can simply think of it as some kind of 5-bit MD128 digital signature for the school to check if files have been modified.

While other users on the Internet at the same time also download this SFV file back to the computer, and then use the content of this file by SFV software to do CRC32 detection of other files.

Because the content of the file as soon as there is any change, its CRC32 checksum will be different, and therefore the value of the information provided by the CRC. This means that the file downloaded from the Internet is not equal to the original file.

When we come to various well-known forums for FTP download, in each folder you can see that there is a SFV file extension of the file, what is it for?

In fact, it is a sub-volume compression packet inspection document, the role is used to check whether there are errors in the payload volume compression package, for FXP, this document is an indispensable component.
