Documentation

LimitTar

This application/library is for limiting the size of a tar archive for spanning data directly across multiple Blu-Ray/DVD discs, flash drives or as files on online storage with file size limits. It tries to fit as many files as possible into a tar archive without creating partial files. This means each tar archive can be restored independently without joining.

This application was mainly developed to be used with aes-pipe for space efficient data encryption using pipes to remove the need for temporarily storing the potentially large archives and encrypted data.

Requirements

  • Python 3.4+

Installation

From the Python Package Index:

pip install limittar

Or download and run:

python3 setup.py install

Command-Line Usage

Use the -h argument for help:

limittar -h
