Case matters
For instance: ".z" and ".Z" represent two very different compression mechanisms (pack and compress respectively). ".c" is C ".C" is C++. There are probably more. --David Garfield 21:35, 1 June 2007 (UTC)
 * Sadly, Windows is not case-sensitive, so a lot of these subtleties are missed. You could add a note to that effect. nneonneo 19:55, 9 July 2007 (UTC)
 * I'm sorry but... Yes. Yes It is. 86.140.103.21 16:37, 2 August 2007 (UTC)
 * Fat32 and NTFS are neither of them case sensitive filesystems. They do store the case for the convenience of the user, but you cannot have two filenames in the same folder that differ only by case, and programs are encouraged not to differentiate based on case (from Microsoft's style guidelines). You can be pedantic and say that it stores the case in most circumstances, but it does not pay attention to the case and is thus not case-sensitive. 66.24.104.37 14:39, 29 August 2007 (UTC)

Cleanup!
If we're going to keep this page, it needs cleanup. I already went through and added another column. The format is now Extension|Description|Application. This makes the most sense (to me, at least). The Application should ideally be the program which is the primary producer of the format, but if that is impossible to determine, a suitable reader may be added. Separate file types with the same extension should get different rows. Case matters, so where it makes a difference, note it. Many extensions are missing or have crappy descriptions and no application. Some filetypes legitimately will have no application (e.g. XML, as it is used for many purposes); many should have applications. Finally, if the file extension has a Wikipedia article (I know XML does, hundreds of others do) then they should be linked. nneonneo 19:54, 9 July 2007 (UTC)
 * I think to re-enforce this convention they need column headers Mrbeardy 07:16, 27 July 2007 (UTC)


 * I for one would much rather see this information cleaned up than deleted. Incidentally, the average Mac filesystem isn't case sensitive either, sadly enough. Wesley 02:51, 31 July 2007 (UTC)


 * Column headers have been added: Ext. | Description | Used by but they could use some shading. I thought "Used by" was more general than "Application" since some things listed (Operating Systems for example) aren't really thought of as applications, but I'm not against changing it.  "Ext." was used instead of "Extension" to keep that column narrow. I'm also in favor of keeping this but its size is a bit unwieldy.  Although, if it ever does get deleted, someone should check that some of the more common types here live on over at List of file formats.  --Georgeryp 18:29, 14 September 2007 (UTC)

There is a lot of spam at the end of the page. There are 3 websites which all link to one central web site which is running a scam. This site pretends to be 'Microsoft partner' but I search MS database and it is not there. —Preceding unsigned comment added by Fedra (talk • contribs) 10:34, 9 October 2007 (UTC)


 * I checked the links at siteadvisor.com and didn't see any complaints. I saw no claim of being "Microsoft Partner" on the filext site but I had JavaScript turned off so maybe the claim was in some ad or dynamic content that appears only with JavaScript? The whois info differed on two of the sites I checked; one claims to be in California and one in Minnesota.  --Georgeryp 02:22, 10 October 2007 (UTC)

Here (http://www.fileinfo.net/filescan.php) is the page where they pretend to be 'Microsoft certified partner'. There is no link/prove behind that logo. I sent a ticket to Microsoft and I wait for an answer now. In the same page there is a program (the program that it is featured on the whole web site) called 'Free system scan'. It pretends that is already scanned my computer and it has found that there is a 94% chance that my computer has a problem. It invites me to download the program. Come on... doesn't smell like scam for you?

And this satellite web site (http://filext.com/file-extension/nfo) is pointing TO EXACT THE SAME strange program 'Free system scan' this time to a different web address, but the web page template is identical with the previous one. This site is also a 'Microsoft partner'. Isn't obvious?

- Ok. I took the risk and installed the program. Instead of 'Free system scan' I end up wit a program called RegistryBoost which WAS NOT FREEWARE!!!! as they said. After one run, the virtual machine refused to load! Also TechGuy warns about this fake program: http://forums.techguy.org/all-other-software/618907-solved-uniblue-registry-booster.html

Notability Query: Flexit
82.56.177.217 added file extensions for FLEXIT software. A Google search doesn't strike me as showing it particularly notable. However, on the second Google page, there are two references to Flexit that don't seem to be from the company itself. What do you people think?--Mumia-w-18 02:25, 9 November 2007 (UTC)


 * More changes of questionable noteworthiness have been made by 82.56.177.217.--Mumia-w-18 15:50, 9 November 2007 (UTC)

VOB and IFO
I just came on wikipedia to find out more about the .VOB, .IFO and .BUP files in the VIDEO_TS folder of a DVD.

I've found .BUP but VOB and IFO are missing from this list.

There is another article with info about them on it but shouldn't they be on this list too?

Text or Binary
In order to help file transfer between different systems (for example through FTP), it would be useful to indicate for each extension if its usage :  is only TEXT (historically known as ASCII) is only BINARY is mixed  EUrbah (talk) 16:03, 21 February 2008 (UTC)

V2i
V2i seems to be some sort of norton image. does anyone knows ? —Preceding unsigned comment added by 195.83.73.194 (talk) 13:45, 24 June 2008 (UTC)

.npf and .opp
Where is the file extension .npf ? I was just using a game and saw it installing its components, or getting them ready to be put into use anyway. And I see .npf - but it's not on this list. I did also see .opp.npf and .tga.npf on this game also, and on the wikipedia list here I see tga - but no .npf - please get it in there! .opp is apparently missing too. thanks ~ GoldenGoose100 (talk) 23:08, 5 January 2009 (UTC)

historical and should be removed
Isn't a lot of this info historical and should be removed? 142.204.142.254 01:33, 12 April 2006 (UTC)

AFD this, please. Not even inclusionists should accept this... --euyyn 17:23, 17 September 2006 (UTC)

Of course most of this info is historical. I think that's the point. I just found the article useful when I was searching for the meaning of a file extension I found on a backup tape. 68.88.192.235 06:07, 14 November 2006 (UTC)


 * Well, that's not the point of Wikipedia. I'm not meaning I'm not happy it was useful for you. It's just this recompilation is a bunch of facts; it's a primary source. A Wikipedia article must be a terciary source. --euyyn 11:54, 17 December 2006 (UTC)


 * Why not create a link for each format? I know it will be a lot of work, but this is really a useful page so maybe it's worth it. --Crashie 20:26, 17 March 2007 (UTC)
