Hello,
I have multiple sub folders in one main folder. These multiple sub folders contains files with the same extension .pgm. How do I go about finding the total number of files in all the subfolders with that specific extension?
I am trying the following:
x = '*.pgm';
AA = size(dir(x),1)
How do I then go through each subfolders?

dir() can now look inside subfolders if you use two asterisks . See the help.

I did a:
dir('**.pgm')
in the main folder, but I got the response '**.pgm' not found.
I also did a
help dir
but could not get a proper way to get the number of files in all the subfolders.

You didn't use it correctly. Check the help again. See my attached demo for how to use it.
