Windows 7 Explorer is not sorting files correctly.  I have sorted them by Name ascending and also done a DIR command,  Sort order is different.  Any ideas?

Because the first chars are numbers, it sorts correctly:
002
17
380
961
2597
3943

Windows sort numbers before alphabets; plus most record management systems perform this action as well.

Many thanks for your observation, I never thought of that.

But I want it to sort alphabetically (as per DOS) not numerically. MS too clever sometimes.

Does it also sort Month names in chronological order?

What I need to do now is modify my VS 2005 code in my application to sort them in the same order as Windows

I am using

file1.FilePath.CompareTo(file2.FilePath) in the IComparer Compare method.

Are there any inbuilt compare routines that act the same as Windows sort or do I write my own?

I guess this might be another post as it is now extending the topic.

Use this function: StrCmpLogicalW(file1.Path, file2.Path)

Just done an Internet search on this very topic and it seems the answer is 'write your own'.

Many thanks guys.  It's always the obvious that you miss!!

Why write your own???
StrCmpLogicalW is used by Windows Explorer to sort files. You can't get closer than that :)

There seems to be no equivalent available in .Net managed code
