Should this be included?

alex1_phang3 · Feb 04, 2007, 07:26 AM

I thinking of burning the whole set of Midori no Hibi I've downloaded to 5 CDRswhen I saw this file named:[A-E]_Midori_no_Hibi.sfv . Does it have to be included in every single CDR with the episode so that I can see them? (Player issue is not a problem coz I'm planning to use ZoomPlayer to view them and I' planing to but the CCCP on my first disk incase I lost everything. . .)

The .sfv file contains the CRC32 checksum that is used to check the file integrity (or download errors in the file) and is not needed to play the file... Usually the checksum is included as a part of the filename, though some groups prefer to use a .sfv file for this information.

You can download this utility that can recreate the CRC32 checksum, which you compare against the .sfv value. Any difference indicates file corruption...

So it means I dun have to include it to play the files but it can be inclluded to check file curruptions? and after it detects file curruption what will happen?

It is used to compare the original files to the one's you downloaded. The .sfv file contains the info on the original files and compares the info it generates on the downloaded files to original info. If they match you know that the files have downloaded correctly and all is fine. If they don't it means you have a 'corrupted' file somewhere that is not the same as the original. You'll have to download that file over again.

This is the big reason I use Azureus. It checks the file for me as soon as it's downloaded. If there is a problem it downloads the correct data for me automatically. If there is a problem in my playback I know it's how the file was burned, not my copy I downloaded. I'm not sure what other bit torrent clients do this but it's the big reason I stick with Azureus.

So, if your check fails you need to redownload the episode it failed on.

Would that be same as the "hash check" thing i get from Bitcomet??

I think it is the same. Related to the download, not viewing the file. So you wouldn't need to keep your .sfv unless you were going to re-share/upload your files. If they're already on CD, you could probably lose the sfv.

Er.. one more thing, subs like negima!? dun come with the .sfv file, so does it mean Azureus wont recheck it?

If the CRC32 value is included in the file name (something like '[1234ABCD]') or is posted on the BitTorrent entry webpage, you can generate the .sfv file and open it with note pad (it's a text file) and manually compare the checksum with the posted value and see if they match...
