Hello,

I copy (with rename) a files:

inputFullFileName = fullfile(FilePath, FileName);
outputFullFileName = fullfile(test, NewFileName);
copyfile(inputFullFileName,outputFullFileName);
    

inputFullFileName =

'/home/user/workspace/QT/Software_2.0_QT/TEST/001_M1_Distance_0.5_AKG_C1000S_F1_MS2/001_M1_Distance_0.5_AKG_C1000S_F1_MS2.mat'

outputFullFileName =

1×1 cell array

{'/home/user/workspace/QT/Software_2.0_QT/TEST_SORT/Dist_1/AKG/Scenery_1/001_M1_Distance_0.5m_AKG_C1000S_F1_MS2.mat'}

i get error:

Error using copyfile

Argument must be a string scalar or character vector.

Error in Result_mover (line 94)

copyfile(inputFullFileName,outputFullFileName);

Try allready to change cell to string:

outputFullFileName = string(outputFullFileName);

But still a error. that is wrong

You ended up with a cell array of character vectors. The {1} pulls out the first entry of that array.

outputFullFileName = fullfile(test, NewFileName);

either test or NewFileName was a cell array of character vector, but you did not happen to post enough code before that for me to see why you ended up with a cell array instead of a plain character vector.
