Regex for Windows path strings

Question

I am trying to use a reg ex which validates Windows path string. I am using the following reg ex

[\w]:\.* .

The following egs should be validated.

Abc.txt
HelloWorld\Abc.txt
..\Hello\World\Abc.txt
C:\Program Files\TaaSera\LiveTrust\Abc.txt

At present C:// is only getting validated. Please help.

Maybe something like this? regexlib.com/REDetails.aspx?regexp_id=345 (there is alot more on that site) — Thaillie

@hindmost: Are you sure. While : forms part of various syntaxes (eg. not capturing groupd) it isn't a meta-character in its own right. — Richard

You seem to be looking for paths of the form "x:\name\…\name.ext. However there are also \\computer\share\…\name` and \\?\D:\very long path to bypass the normal file length limits. See MSDN for details. — Richard

Try with this regex:

^[\w\\.:\s]+?\.\w{2,4}

Abc.txt in this Abc$& is also getting accepted. I guess these special characters are not allowed in windows file name

@user2998990 ok, what about ^[\w\\.:\s]+?\.\w{2,4}?

Windows "normal" paths are driver letter, colon, backslash, and then names separated by backslashes.

@m.cekiera : seems ok... Thanks a ton. :)

@m.cekiera : C:// is not getting validated.
