Basically I have a big directory (>10GB)(each subdir only has a few other subdirs) and want to do sth to any files that changes. I can't just go through all the files and check, because it takes to long and uses about 90% of my CPU :(.
This is how it looks basically:
dir dir/subA dir/subA/subAsubA dir/subA/subAsubB ... dir/subB dir/subB/subBsubA dir/subB/subBsubB ... dir/SubC dir/SubD ...
My thought was like this(file "test" in subBsubA chaged):
Check dir -> dir changed -->Check subA -> subA didn't change -->Check subB -> subB changed --> Check subBsubA -> subBsubA changed --> Check all files
But sadly the change of a file only effects the modification date of the direct parent directory :(
