Hello,
I have a folder:
Testfolder
Inside are:
1.mat
1.txt
1.wav
SubTestfolder
Inside SubTestfolder are:
2.mat
2.txt
2.wav
I do
Del_path = fullfile(TestFolderPath,SubTestFoldername);
delete(Del_path,'*.mat')
I was waiting that 2.mat should be deleted, but it will be 1.mat deleted, not 2.mat. Why? How can I delete files/all files in subfolder?
Thank you!

use dir('**/*.mat') to find files in subfolders in one shot and then use a for-loop to delete the files.

Thanks, but it is to complicated. I found easy way:
delete(fullfile(SubfolderPath,'*.png')) % or '*'
