dirtools3 is a utility package that helps you to scan file system folders to collect statistical information about their sub contents (size, file count, access time, modify time, change time etc. for each sub folder or file). It also provides cleanup method to reduce their total size by removing low-redundant items in given order. It is written in Python and currently supports only Python version 3.6 or higher.
You can use CLI script to invoke the library if you don't need to process each item individually within another application. The dirt script is delivered to your environment executable folder when you install this package. To use dirt command, you will also need to install Python click and tabulate dependencies.
This command line utility is fully capable of displaying items (or trimmed items) in specified tabulate format or in csv with any given sorting option:
$ dirt -s largest /path/to/Python-3.6.0-source

40 items with total of 121.31 Mb data; took 0.288 second(s).Default sorting for the dirt command is dirtools.scanner.SortBy.ATIME_DESC.
There is a scanning instantiating class dirtools.scanner.Folder that takes care of the parallel folder scanning process in the default event loop under the hood using async generators. Therefore, it is preferred to start and trigger the scanning process as early as possible. Sample usage of Folder would be listing a folder by using Folder class:
from dirtools import Folder, SortBy
from dirtools.utils import bytes2human
path = '/path/to/Python-3.6.0-source'
# There is no default ``sort_by`` argument within the scanner class
folder = Folder(path, SortBy.LARGEST)
# ... do other stuff if possible, path scan is about to start in parallel.
# next line will actually _block_ and wait for scanning to complete:
size_human = bytes2human(folder.total_size) # from integer in bytes
# None of the rest will block anymore as the scanning has been completed
assert len(folder) == 40
assert size_human == '121.31 Mb'
# The items (sub directories and/or flat files) are ready
# in the given SortBy.LARGEST order:
largest_item = next(folder.items())
assert largest_item == {
'atime': '2017 Apr 09 06:18',
'ctime': '2017 Feb 07 01:07',
'depth': 7,
'mtime': '2017 Feb 07 01:07',
'name': 'Lib',
'num_of_files': 2184,
'size': '35.81 Mb'}
# If you some reason need the non-human raw values
# (such as size in bytes, creation and modification time in timestamps)
largest_item_raw = next(folder.items(humanise=False))
assert largest_item_raw == {
'atime': 1491718693,
'ctime': 1486429664,
'depth': 7,
'mtime': 1486429664,
'name': 'Lib',
'num_of_files': 2184,
'size': 37552912}
# Re-ordering without the whole file system scanning process is possible
folder.resort(SortBy.SMALLEST)
smallest_item = next(folder.items())
assert smallest_item == {
