Thread Subject: How to browse directory automatically?

Hello everybody,

I need to browse in some folder in order to "go up one level" from the Current Directory in MatLab.
If I use the command "cd", I obtain an adress like this:

C:\goofy1\goofy2\goofy3\goofy4

My m file needs to go up one level, in goofy3, and after going down again in some other folder, different from goofy4.

I want to avoid the "uigetfolder" command, but I want that my program search without user input of course.

I didn't find on the help a command which can absolve the function "go up one level".

My code is something like this:


part_path=?(cd);

new_path=[part_path,'\otherfolder\otherfolder'];

So that now in new_path I have a path which can direct me in another folder, but that is not in the cd folder.

I could type directly the new part_path, but when I work on different pc I have to type again the new part_path.

Thank you in advance,

Luca

No.

1) I don't need to change the current directory. My current directory have to stay the same.

2) I need to save and load files in another folder, which is NOT nested in my Current Directory. I have to go up of one level, and then go to save my files and variables in another folder, which is not cd.
Something like that:

save([part_path,'\somestuff\somestuff'],'Goofy')

The problem is that part_path is different from cd. Or, at least, is the first part of my cd:

If my cd is C:\goofy1\goofy2\goofy3, my part_path should be C:\goofy1\goofy2

I can type directly the path IF I work always on the same pc... But I don't, so, there is some way to obtain the part_path from the cd command, or something like that?

I could use the "uigetfolder" but is not very convenient.

Do it on pwd (current directory) and you get the parent directory path.

Then use '..' to navigate relative to the current directory.

Use '..' to navigate up in the directory hierarchy.

Do you work across a network? If so, the target disk has to
be mounted/accessible from the PC where the program runs.

Or you could use the very convenent '..'.

I'm so sorry that I didn't get what you were meaning by cd .. !

You saved me, thank you so much!

I'm confused by your description. Anyhow, perhaps the following helps:

You are working in the directory "C:\A\B\C" and you want to save a file in the a folder C2, which is in the parent directory:
  save('C:\A\B\C\..\C2\DataFile.dat', Data)
This writes: C:\A\B\C2\DataFile.dat
If you need a folder "D", which is in the path two levels on top of CD, use:
  newPath = fullfile(cd, '..\..\D');
So you can use '\..' to go one (or more) level up and add further folders afterwards.

Good luck, Jan
