Can you show what SFV file contains inside?
from openhashtab.
The SFV file Only contains the file's relative path and file's CRC32 algorithm, It doesn't contain any other hash algorithm except CRC32. Though SFV file is not very safe. but its calculation speed is very fast and we can still use it to verify when one file only provide a SFV file to us for verification. Here is an example SFV file
; File's relative path files' CRC32 algorithm
; (This line and Previous line are only annotates)
new.txt 3bbb5ca3
folder\02.zip c1b2af23
folder\20240408_210417.iso 46175043
You can regard all SFV file as only contain CRC32 algorithm and only calculate the CRC32 algorithm in spite of other hashes, like MD5 File only calculate MD5 algorithm, It can increase the speed and give us the right output, Thank you!
SFV means Simple File Verification.
Simple File Verification (SFV) format Brief introduction are below:

What about decreasing number of spaces before CRC values?
new.txt 3bbb5ca3
folder\02.zip c1b2af23
folder\20240408_210417.iso 46175043
Or:
3bbb5ca3 new.txt
c1b2af23 folder\02.zip
46175043 folder\20240408_210417.iso
from openhashtab.
The situation are the same like before. Number of spaces has no effect to SFV files, My example is just to get a more complete understanding of the structure of an SFV file. Your examples are all true.
You only need to know that SFV file only contains file's relative path and CRC32 algorithm.
Sometimes SFV file contains some annotates start with semicolon ";
", but they are of no use.
