I am looking for a program that can list all files in a folder/drive as well as all sub-folders, recursively, hierarchically, and with folder/file size in Windows. The output should be saved in a text files.

Here is an example of output I would like to have:

├── [1.9M]  aclArc-20080325.tgz
├── [ 64K]  aclArc-20080325.tgz.1
├── [ 15G]  backup
│   └── [ 15G]  pubmed.zip
├── [ 293]  connection_ssh2.sh
├── [ 242]  connection_ssh.sh
├── [244G]  corpora
│   ├── [ 15G]  cv_corpus_v1
│   │   ├── [ 12G]  cv_corpus_v1.tar.gz

I tried:

1) tree accessible natively in cmd.exe, but it doesn't have any option to display file sizes:

C:\folder>tree /?
Graphically displays the folder structure of a drive or path.

TREE [drive:][path] [/F] [/A]

   /F   Display the names of the files in each folder.
   /A   Use ASCII instead of extended characters.

2) On Ubuntu, one can use tree --du, for tree 1.6 and above:

--du For each directory report its size as the accumulation of sizes of all its files and sub-directories (and their files, and so on). The total amount of used space is also given in the final report (like the 'du -c' command.) This option requires tree to read the entire directory tree before emitting it, see BUGS AND NOTES below. Implies -s.

so I tried tree.exe provided in Cygwin and gnuwin32, but both of them come with tree version 1.5. UnxUtils.zip and C:\Program Files (x86)\Git\bin don't contain tree.exe.

  • Maybe Cygwin is an alternative, it has a tree --du possibility.

  • What version of Windows are you using? It might be possible without too much trouble to write this yourself in PowerShell. Feb 19, 2018 at 18:58
  • @JeffZeitlin I use Windows 7 and Windows 10. Feb 19, 2018 at 19:00
  • @albert I tried tree provided in Cygwin and gnuwin32, but both of them come with tree version 1.5, which doesn't have --du. UnxUtils.zip and C:\Program Files (x86)\Git\bin don't contain tree.exe. Feb 19, 2018 at 19:01

    @FranckDernoncourt, the version of Cygwin (32-bit) has version: $ tree --version tree v1.7.0 (c) 1996 - 2014 by Steve Baker, Thomas Moore, Francesc Rocher, Florian Sesser, Kyosuke Tokoro

In python the first example in os.walk would be simple to modify to give you what you need.

The example:

import os
from os.path import join, getsize
for root, dirs, files in os.walk('python/Lib/email'):
    print(root, "consumes", end=" ")
    print(sum(getsize(join(root, name)) for name in files), end=" ")
    print("bytes in", len(files), "non-directory files")
    if 'CVS' in dirs:
        dirs.remove('CVS')  # don't visit CVS directories

With humandfriendly installed with pip install humanfriendly to make the friendly format of the sizes.


from humanfriendly import format_size
import os
from os.path import join, getsize
from os.path import join, getsize, split

for root, dirs, files in os.walk('.'):
    depth = len(split(root))
    print('--' * depth, split(root)[-1], '[%5s]' % format_size(sum(getsize(join(root, name)) for name in files), binary=True))
    for fname in files:
        print('| '*depth, fname, '[%5s]' % format_size(getsize(join(root, fname)), binary=True))

tree.exe from cygwin/gnuwin (http://gnuwin32.sourceforge.net/packages/tree.htm) can do that, also in version 1.5 already. The option you want to consider is -h (for "human readable"): tree -h
