message: Are SFV's also used to combine files downloaded in segments into the 'original' file?  —Preceding unsigned comment added by 66.105.208.12 (talk) 07:09, 24 November 2007 (UTC)
replies: text: Nope. Only for checking files against corruption or modification. James.Denholm®Talk to me... 09:51, 3 May 2009 (UTC)

text: All the SFV tools I've tested fail to recognize this as a file. This was poorly-thought out. Why not do like COBOL and use an asterisk to denote comment lines? A normal colon would also have avoided this problem. DancesWithGrues (talk) 16:55, 17 April 2013 (UTC)
replies: text: A workaround would be to enclose the filename with "quotes". However existing programs will need to be modified to recognize this. DancesWithGrues (talk) 22:04, 17 April 2013 (UTC)

message: if you want to check an sfv against the contents of that directory, this shell script will work. 
(not for the the faint at heart with the command prompt, requires proper line endings -- hence dos2unix at the beginning).

:While I realize that this can be useful to people, Wikipedia is not the place to simply dump scripts on, and Wikipedia talk pages should be used for discussing improvements to the article. -- intgr [talk] 12:49, 15 November 2007 (UTC)
replies: text: I know you (216.101.164.52, in 2007) mean well with that script, and are just trying to help-- but within a minute or two or testing this code, I found that it's buggy in several really fundamental ways, and I was able to spot and write exploits for huge security holes. I've deleted the code from this page. Anyone who has copied that code into a program that they use, should delete it. But thank you for the effort. -- Sburke (talk) 08:29, 24 March 2016 (UTC)

message: So is SFV simply a de facto file format or is there a standard algorithm, etc.? If so, who invented it, etc. Ham Pastrami 12:05, 2 December 2007 (UTC)
replies: text: The standard algorithm is mentioned in the article, and it's quite common - it is used in the warez scene.--134.147.252.130 (talk) 13:12, 28 August 2008 (UTC)
replies: text: It's also included in shareware CDs that were released with computer magazines in the 90s (which have made their way into Archive.org's software library). There are also ~5,483  files indexed on GitHub.com as of this writing, which confirms that the format is commonplace, albeit as a legacy file format. It's by no means specific to WaReZ.

text: The checksum that is used (CRC32) is standard, the file format is not. What exactly do you think is missing? -- intgr [talk] 07:36, 29 August 2008 (UTC)
replies: text: CRC can use any polynomial. To be used as a standard, a specific polynomial must be chosen. We are left to guess that CRCs stored in SFV are expected to use a specific polynomial (can this be confirmed?) and it is the same polynomial as IEEE (can this also be confirmed?) since it is probably the most common. Article still hasn't answered my original question of who came up with SFV or how its usage spread, so I've already stated what's missing. Ham Pastrami (talk) 09:26, 20 March 2010 (UTC)
