MATLAB: Finding how many folders are in an other folder and how many files (.xls files) are in each folder

Question

For example there is a folder in name of 'a'. in 'a' there are these folders: 'b','c','d','e',… and in 'b' there are 4 .xls files and in 'c' there are 7 .xls files,…. now it's needed knowing how many folders are in 'a' and in each folder how many .xls files there are.

Answer 1

FolderA='C:\mydocument\c';
f=dir(FolderA)

will give you a list of files and folders. Checking f.isdir will tell you how many are folders. Note that f(1) and f(2) are usually '.' and '..'

Files=dir(fullfile(FolderA,'b\*.xls')) will tell you how many .xls files are in the \b folder.
