Delete files inside subfolder

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 '*'
