Finding empty directories
I know it sounds trivial but as usual the trivial things are those that are most annoying. Running through the harddrive of my notebook i came accross way to much garbage manifesting itself through empty directories.
After some 30 minutes of "search and despair" i simply decided to stop clicking.
Here is a result of that after 5 minutes. Never underestimate the batteries:
import os from os.path import join, getsize for root, dirs, files in os.walk('c:\\'): if len(dirs)==0 and len(files)==0: print root
The results gave me the creeps. You only get the empty directories at the lowest level. So here is a better version:
import os from os.path import join, isfile def walksub(dir): isEmpty=True subDirs= for entry in os.listdir(dir): try: if isfile(join(dir,entry))==True: isEmpty = False else: subEmpty = walksub(join(dir, entry)) if subEmpty==True: subDirs.append(join(dir, entry)) else: isEmpty=False except : print ("error checking: "+entry) isEmpty=False if isEmpty == False: for subDir in subDirs: print subDir return isEmpty walksub('c:\\')
Now here is the 1 million dollar question: "What are all those empty directories good for?"
