LongPathShutil 0.4

Drop-in replacement for shutil with long path support for Windows

LongPathShutil

LongPathShutil is a drop-in Python wrapper for the methods of the built-in shutil library, providing enhanced support for long file paths on Windows. It leverages the \\?\ prefix to bypass the 260-character path length limit on Windows systems, and to be able to handle deeply nested or long file names. More info on the long path limitations on windows here

Features

• Seamlessly integrates long path support on Windows.
• Fully compatible with the existing shutil functions. The functions only.
• Automatically prefixes paths with \\?\ when necessary.
• Offers functions to enable or disable long path support via the Windows registry at least for the applications supporting it. (Needs to be executed as admin)

Installation

You can install it like so:

pip install LongPathShutil

Usage

Enabling Long Paths in the Windows Registry

You can try programmatically enabling long paths via the registry. This does however require admin access and does not always work. Otherwise you can use the module as drop-in replacement for shutil on windows.

import LongPathShutil

# Enable long paths in the Windows registry (requires administrative privileges)
LongPathShutil.enable_long_paths_on_registry()

Basic File Operations

import LongPathShutil as shutil

# Copy a file with long paths
shutil.copy(r"C:\very\long\source\path\file.txt", r"C:\another\very\long\destination\path\file.txt")

# Move a directory with long paths
shutil.move(r"C:\very\long\source\directory", r"C:\another\very\long\destination\directory")

# Remove a directory tree with long paths
shutil.rmtree(r"C:\very\long\path\to\directory")

Full API

The LongPathShutil class provides all the functions available in shutil with the addition of long path support:

• copyfile(), copy(), copy2()
• move(), rmtree(), copytree()
• make_archive(), unpack_archive(), get_archive_formats(), and more.

See the complete list of functions here.

Why Use LongPathShutil?

By default, Windows imposes a 260-character limit on paths, which can cause problems when dealing with deeply nested directory structures or long filenames. This module automatically adds the necessary prefix to bypass this limitation, allowing for seamless file operations across various platforms.
