Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

If I have a file structure that is several directories deep.

eg.

B:\DIR1\DIR2\DIR3

and I am currently in DIR3

How do I, in a single command, change back to B:\ ?

I know CHDIR .. takes me back one but CHDIR B:\ doesn't work.

wait, chdir never takes a drive anyway. Just chdir \ is supposed to work.

(each drive remembers its path)

What he said. Follows is a quote from the V4.3a manual.

Change the current working directory on the SD card to ‘dir$’
The special entry “..” represents the parent of the current directory and
“.” represents the current directory.


It looks like you set DIR$ first then issue CHDIR it seems an odd way to do it.

As Dylan says"

CHDIR "..\..\.."

will get you back from DIR3 to B:\

Well, there's an answer I should have asked the question to long ago. I've always kept the directory structure just one level deep because of this and it's made my directory lists rather longer than I'd like.

Yep. Leave out the drive letter.

I don't know which OS I was thinking. :)

Hello Nick!
if you want to go back to the root, no matter what subdirectory you are, try

Chdir "\"

I must admit, using the quotes is something I fail to do!
