Saving file at different directory

Question

0 个投票

Hi,

I am having trouble changing the directory where my file should be saved. I use the command:

[file, pathdir] = uiputfile('FileNAME.txt');

then I choose a new directory. However, each time my file is saved in the current folder (where the .m script is saved).

Can anyone explain why this is and how to solve it?

You need to use FULLFILE to include the path in the filename, e.g.:

[F,P] = uiputfile('FileNAME.txt');
fnm = fullfile(P,F); % <------ you need this!

and then use its output with whatever command you are using to save your data, e.g.:

writematrix(..,fnm,..)

I'd suggest you use more descriptive variable names

[baseFileName, outputFolder] = uiputfile('FileNAME.txt');
fullFileName = fullfile(outputFolder, baseFileName); % <------ You need this!

but it should work, so can you "Accept this answer" to award Stephen his reputation points? Thanks in advance.
