Search for File names in all capital letters/upper case

[jinsight]

Any ideas how to search for file names that are in all caps? Any help appreciated.

jinsight,

Code: Select all

(?-i)^[A-Z]+$

[x] RegEx

Roman

Using (?-i)^[A-Z]+$ in a subfolder off of the root with files and multiple subfolders, a few all cap folders and files were found but many were missed.

jinsight,
Maybe they contained numbers and other characters in addition to all caps?
Adjust [A-Z] as appropriate, eg.:

Code: Select all

[A-Z0-9!@#$%^&()]

Roman

To ignore the extension and only discard non caps:

Code: Select all

(?-i)^[^a-z]+\.*[^.]*$

Edit: Include files with no extension

ZoSTeR,
Ah, much better, excluding lowercase, stupid me.

Hmm... but how to exclude "ABCdef" with no extension?

(?-i)^[^a-z]+\.*[^.]*$

This would work, and I think it's easier to read, due to the "0 or 1" quantifier:

Code: Select all

(?-i)^[^a-z]+(\..+)?$

2jinsight and others:
In case you didn't know:
For a quick test, w/o using the search (Alt+F7), just use the "Mark files" dialog (Numpad+)
and prefix "<"

e.g.

Code: Select all

<(?-i)^[^a-z]+(\..+)?$

or just save this RegEx as a search preset (important to remove the search path for this) and select this preset afterwards in the "Mark files" dialog.

This fits all my test cases:

Code: Select all

(?-i)^[^a-z]+(\.[^\.]+)?$

For:

Code: Select all

abc.txt
abc.xyz.txt
abc123.txt
aBCD
BCD
BCD.txt
BCD.aYZ.txt
BCD.XYZ.txt
BCD123
BCD123.txt
BCDabc

This fits all my test cases:

Code: Select all

(?-i)^[^a-z]+(\.[^\.]+)?$

I see, the only difference to my expression is that it doesn't match
BCD.aYZ.txt

Anyway, there are still cases when an all-digit file name is matched, e.g.:
123.txt
so we should stipulate at least one upper case letter:

Code: Select all

(?-i)^([^a-z]*[A-Z][^a-z]*)+(\.[^\.]+)?$

All posters,

Thanks for all the effort everyone put in to find a useful answer.

I had searched the web but found nothing close.

(?-i)^([^a-z]*[A-Z][^a-z]*)+(\.[^\.]+)?$ worked the best for me.

It saved a lot of time finding old all caps file names.

Much appreciation to all.
