A tool to selectively compress or copy files.
For example, '.html' and '.csv' files in a directory can be specified to be compressed and all the rest are copied.
If the specified files are of '.zip' or '.7z' extensions then they are re-compressed to 7zip using the specified (default=9, maximum) LZMA2 compression level.
It performs in-memory processing of files thus no unnecessary intermediate disk operations are performed.
Configurable multi-processing is used to make use of available CPU threads / cores.
Note that if '.zip' and '.7z' files are specified to be (re)compressed and two files of the same name are present in the same directory (e.g. 'test.zip' and 'test.7z') then operating system 'first come first served' conditions apply.
Requires Python 3.9 or above.
Create a virtual environment in the source directory and install dependencies:
python3 -m venv venv
source venv/bin/activate
pip intstall --upgrade pip
pip intstall --upgrade setuptools
pip install -r requirements.txtpython file-repacker.py --help
Compress .zip, .7z and .txt files with extended logging information:
python file-repacker.py --source_directory /<your>/<source>/<directory> --destination_directory /<your>/<destination>/<directory> --file_extensions_to_compress ".zip,.7z,.txt" --log_level INFO
