Possible Duplicate:
Are all versions of windows case insensitive?

I've got 2 files on a Unix server which I tried to ftp (using FileZilla) to a Windows 7 machine - tdda.png and TDDA.png - initially FileZilla complained that TDDA.png was already a file when I tried to transfer TDDA.png, so I renamed it to TDDA2.png before transferring it. I then tried to rename it back to TDDA.png in Windows and get the notification:

"Do you want to rename 'TDDA2.png to ''tdda(2).png? There is already a file with the same name in this location"

Has Windows 7 got some case-insensitivity built in somewhere? I've never experienced it with any other version of Windows...

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Windows has ALWAYS been case-insensitive. It's one of the discerning ("user-friendly") features that make it different than systems like *nix (actually it predates Windows to DOS). – Ƭᴇcʜιᴇ007 Sep 22 '12 at 14:46
Windows is case-preserving, but case-insensitive as far as most file operations go. It'll remember the case used when you create (or rename) a file, but for all other operations the case of the filename given is ignored and does not need to match the file stored. – martineau Sep 22 '12 at 15:57

By default Windows is case insensitive, but by enabling the "POSIX subsystem" case sensitive filenames are possible. This feature is used in the "Microsoft Windows Services for UNIX" (Windows acts as an NFS file server and other).

See Stackoverflow question How to make an ntfs case sensitive

Nice answer. You should go add it to the original question. :) – Ƭᴇcʜιᴇ007 Sep 22 '12 at 16:45
