PyFilesystem is a Python-only module and can be installed from source or with pip. PyFilesystem works on Linux, Mac and OSX.
To install with pip, use the following:
pip install fs
Or to upgrade to the most recent version:
pip install fs --upgrade
You can also install the cutting edge release by cloning the source from GIT:
git clone https://github.com/PyFilesystem/pyfilesystem.git cd pyfilesystem python setup.py install
Whichever method you use, you should now have the fs module on your path (version number may vary):
>>> import fs >>> fs.__version__ '0.5.0'
You should also have the command line applications installed. If you enter the following in the command line, you should see a tree display of the current working directory:
fstree -l 2
Because the command line utilities use PyFilesystem, they also work with any of the supported filesystems. For example:
fstree ftp://ftp.mozilla.org -l 2
See Command Line Applications for more information on the command line applications.
PyFilesystem requires at least Python 2.6. There are a few other dependencies if you want to use some of the more advanced filesystem interfaces, but for basic use all that is needed is the Python standard library.
Before you dive in to the API documentation, here are a few interesting things you can do with PyFilesystem.
The following will list all the files in your home directory:
>>> from fs.osfs import OSFS >>> home_fs = OSFS('~/') # 'c:\Users\<login name>' on Windows >>> home_fs.listdir()
Here’s how to browse your home folder with a graphical interface:
This will display the total number of bytes store in ‘.py’ files your home directory:
>>> sum(home_fs.getsize(f) for f in home_fs.walkfiles(wildcard='*.py'))
