Python - Get total amount of bytes used by files -

-

i'm trying total amount of bytes used files.

what i've got far following.

 def getsize(self):     totalsize = 0     size = 0     root, dirs, files in os.walk(r'c:\\'):         files in files:             size = os.stat(files).st_size     totalsize = totalsize + size

however, when running this, following error pops filenotfounderror: [winerror 2] system cannot find file specified: 'hiberfil.sys'

does know how can fix error , correctly calculate total bytes on disk?

edit: after looking @ more, came following code.

def getsize():     print("getting total system bytes")     data = 0     root, dirs, files in os.walk(r'c:\\'):         name in files:             data = data + getsize(join(root, name))     print("total system bytes", data)

however following error. permissionerror: [winerror 5] access denied: 'c:\\programdata\microsoft\microsoft antimalware\scans\history\cachemanager\mpscancache-1.bin'

this may help:

import os import os.path  def getsize(path):     totalsize,filecnt = 0,0     root, dirs, files in os.walk(path):          file in files:             tgt=os.path.join(root,file)             if os.path.exists(tgt):                  size = os.stat(tgt).st_size                 totalsize = totalsize + size                 filecnt+=1     return totalsize,filecnt  print '{:,} bytes in {:,} files'.format(*getsize('/users/droid'))

prints:

110,058,100,086 bytes in 449,723 files

or, if permission error, use this:

            try:                 size = os.stat(tgt).st_size                 totalsize = totalsize + size                 filecnt+=1             except (#permission error type...):                  continue
