I need to extract information how much files are in some directory tree:
/.../testRoot/test1/test11/..../file1
/.../testRoot/test1/test11/file2
/.../testRoot/test1/test11/..../file3
/.../testRoot/test1/test11/file4
.....................................
/.../testRoot/test1/test1n/fileq
/.../testRoot/test1/test1n/..../filew
/.../testRoot/test1/test1n/filee
/.../testRoot/test1/test1n/.../.../ .../filer
How to calculate how many files are inside of testRoot? Thanks.
