How to find the full file path with only a folder?

I am given the string of a folder name

Folder = 'Wallpapers'

How would I get the full file path of the folder 'Wallpapers' so that it looks something like this:

C:\Users\Bob\Pictures\Wallpapers

s = what(Folder);
s.path

Thank you so much! I was used what() before but I didn't know you need the .path part to retrieve the file path.

I've run into an error where it says:

Insufficient number of outputs from right hand side of equal sign to satisfy assignment.

What do I do to fix this error?

[madhan ravi]

Show the code that you're trying. Attach a screenshot. Also what does:

whos % return?

"What do I do to fix this error?"

The code provided by madhan ravi only works if there are MATLAB-related files in that folder. If there are not, then s is empty. There is nothing you can do to "fix" what's designed behavior.

Thank you Stephen!

My code is supposed to take the name of a folder and open a directory to it.

folder_name = 'Wallpapers';

s = what(folder_name);
path = s.path;

location = dir(path);

From what I've read, what() can only give the path of the folder if the folder contains MATLAB files.

Is there a way to get the path file if there are no MATLAB files in the folder?

Until MATLAB has an inbuilt function for this, the general solution is to download one of these:

https://www.mathworks.com/matlabcentral/fileexchange/28249-getfullpath

https://www.mathworks.com/matlabcentral/fileexchange/57297-relative-to-absolute-file-name

or use something like:

folder = '../Wallpapers';
prv = pwd();
cd(folder)
out = pwd()
cd(prv)
