Directory and file listing
Can someone please help me with some code.
I want to be able to put the contents of a drive or folder into 2 string variables, one with each filename and the other with the folders.
The values need to be separated by a ","
(no quotes) and preferably in alphabetical order.
Please supply some code...thanks.
And no. i do not want to use any controls to do this.

eric37..this is perfect..if you could please modify it so that i can view all files...(hidden etc) and not just the normal files...
thanks
thanks

thank you vey much

wait a moment....how can i view the listings of other folders..and not just the root directory..
it doesnt work.
can you please modify the code to let me get listings of other folders....thanks
it doesnt work.
can you please modify the code to let me get listings of other folders....thanks
Try the code I posted, it works for recursive listing.
ASKER
I have tried your code and it is very slow.
Im sorry but i would rather use eric37's code as it is fast, if only it could do other folders. Can you please help me to be able to do this..thank you

The code is fast because it only returns top level directories for any given path. If you recurse into all subdirectories, any coding will slow down.

But cant i just get a listing of all the directories and files in a path that i specify.
Just in that path.
I dont want to look into all subdirectories, i just want the files and directories in a given path, no subdirectories of those directories.
Can you explain to me how to do this....
cheers

Gotta ask, you mean my code looked slow or did it take a longer time to process than erick's? <g>
I don't felt like optimizing the code, since I felt that someone that wanted to get all filenames/dirnames into one big string, can't be thinking about performance. ;)

Yes there is a bug...
Get rid of the line

And if you want to view the contents of the windows directory call:

Text2.Text = GetDirs("c:\windows\", vbNormal) 'list files
End Sub
