Since when are user names case sensitive? In most systems I know user names are not case sensitive to avoid many problems, like users forgetting the case. —Preceding unsigned comment added by Danobrega (talkcontribs) 08:54, 8 September 2010 (UTC)

This is wrong: " German there is no uppercase form for the sharp s ("ß")." The uppercase form for the sharp s is "SS". Can't find the edit button for the upper part of the article, so i can't correct it myself.

I see Wikipedia itself neglects to volunteer to smash case, for instance the articles Case sensitivity and Case Sensitivity are NOT NOT NOT the same article.

Is there an example in Wikipedia where this neglect to smash case actually helps people, apart from the significant example of perhaps measurably reducing the work of the servers that host Wikipedia?

Brion you might think I'm some kind of anti-american nazi :-)

Why so? Case-sensitivity is probably common to all languages that use the tiny fraction of writing systems which exhibit case. --Brion

I have noticed, that the Page Titles are case sensitive (except the first letter). But didn't find any explanation about that. While it might be completely offtopic here, does that make sense? Is there any discussion or explanation about that topic, and I only didn't find it?

Thanks, User:NilsB


I would think "case sensitivity" is correct, but as an adjective or adverb, wouldn't it be "case-sensitive" and "case-sensitively" etc.? — FREAK OF NURxTURE (TALK) 04:59, 2 November 2005 (UTC)

Agreed. When two words are used as a single adjective, a hyphen is necessary. dachshund2k3 (talk) 02:04, 30 September 2008 (UTC)

Case sensitive web search engines?[edit]

This may be not be the correct place to ask for this, but I needed to do a case sensitive web search and came up with.. nothing.

As good as Google otherwise is, it lacks this feature. Alta Vista supposedly had this, but doesn't anymore. Any suggestions? Anything on this on Wikipedia? Having just looked at this article tonight (i.e. December 8 2009), I was extremely surprised to see that this article did not mention Google as a search engine which, as far as I know, is NOT case-sensitive, so that you will get equivalent number of hits on Google if type in a term in capitals or lower-case. This has long been my understanding on Google - am I right? ACEOREVIVED (talk) 22:14, 8 December 2009 (UTC)

Can anyone hazard a guess at why this article has been the target of so much vandalism over the last day or 2? -- Smjg (talk) 22:17, 29 October 2008 (UTC)

It's linked in MediaWiki:Noarticletext, MediaWiki:Noexactmatch (through the redirect case sensitive), and MediaWiki:Noexactmatch-nocreate (through case sensitive) which was created on 25, October 2008. So the visibility of this system message may explain the important rise in traffic of case sensitive, [1], whilst the traffic of case sensitivity alone relatively diminished. This explains the cumulated traffic and so the level of vandalism here. Cenarium Talk 01:39, 1 November 2008 (UTC)

Web site addresses are case sensitive??[edit]

Under the list of examples of case sensitive data, I am confused as why web site addresses are listed. Domain names are not case sensitive, but I believe depending on the web hosting software, the page name may be. is the same as EXAMPLE.COM, but may not necessarily be the same as

I think web site url's should be removed here as it could lead to confusion. —Preceding unsigned comment added by Goodmorning2255 (talkcontribs) 03:48, 13 February 2010 (UTC)

As a general rule, URLs are case sensitive, on a number of counts:
  • Many web servers are Unix-based, so that the file system is case sensitive.
  • Any query string is part of the URL, and generally speaking is case sensitive.
  • Even on case-insensitive file systems, server-side or client-side scripting may make use of the capitalisation by which a page is accessed.
  • Even excluding any query string, URLs may not correspond to actual file names, and so the server may treat them as case-sensitive or not independently of whether its file system is case sensitive.
  • Even if for a given website none of these is the case, user agents don't know this, and thus must treat page.html, Page.Html and page.HTML as distinct.
In any case, the way to deal with a statement being confusing isn't to remove it (except possibly as a temporary measure), but to work out how to write it to avoid confusion. -- Smjg (talk) 13:36, 3 May 2010 (UTC)

QBASIC said to be case-sensitive - definitely wrong![edit]

Or I cannot understand what "case sensitive is"

In QBASIC IDE, you can type

print x

And then you press Enter on last line, all instances of X converted to last used casing (x). (and running it prints 10)

If you create such a program outside IDE, it converts on load.

(As example of case sensitive Basics I can cite Liberty Basic / Just Basic. In them, above program stays "as is" and then run, prints 0 (because x is undefined) ) (talk) 06:24, 22 April 2010 (UTC)

Case sensitivity in speech[edit]

In one Star Trek: Voyager novels, one of the characters meets a female Q and asks her if she is Q. "No, I'm q", she replies, "can't you hear the lower case?" How are you supposed to hear the lower case? JIP | Talk 22:01, 9 November 2011 (UTC)

Edit request on 9 November 2012[edit]

Change the section title: With computer systems of gov of india into: Use in computer systems Reason: Obviously India has nothing to do with this topic, there is no mention of India anywhere else other than in this title. Abuyakl (talk) 19:21, 9 November 2012 (UTC)

Done. Reverted older vandalism that was not previously caught. Thank you for helping to improve Wikipedia. —KuyaBriBriTalk 20:05, 9 November 2012 (UTC)

Windows - NTFS[edit]

"Current Windows file systems, like NTFS, are case-sensitive; that is a readme.txt and a Readme.txt can exist in the same directory. Windows disallows the user to create a second file differing only in case due to compatibility issues with older software not designed for such operation." Not just older software. One would struggle to find any newer software that is compatible with it either. (talk) 16:28, 14 January 2014 (UTC)


In computers, some examples of usually case-sensitive data are


Imho this is wrong: most computers use Windows and although it is possible, to use upper- and lower-case filenames in Windows with NTFS or VFAT, the file names are not case sensitive: it is impossible to create two files in the same folder, when the only difference in the filename is the case of a letter and all the file system operations are also case insensitive. --MrBurns (talk) 00:03, 27 June 2014 (UTC)
