PyFileIndex - pythonic file system index

The pyfileindex helps to keep track of files in a specific directory, to monitor added files, modified files and deleted files. The module is compatible with Python 3.7 or later but restricted to Unix-like system - Windows is not supported.

Installation

The pyfileindex can either be installed via pip using:

pip install pyfileindex

Or via anaconda from the conda-forge channel

conda install -c conda-forge pyfileindex

Usage

Import pyfileindex:

from pyfileindex import PyFileIndex 
pfi = PyFileIndex(path='.')

Or you can filter for a specifc file extension:

def filter_function(file_name):
    return '.txt' in file_name
    
pfi = PyFileIndex(path='.', filter_function=filter_function)

List files in the file system index:

pfi.dataframe

Update file system index:

pfi.update()

And open a subdirectory using:

pfi.open(path='subdirectory')
