git lfs

storing large binary files in your repository will slow down performance considerable. use git lfs extension to circumvent this problem. it is very simple and transparent to use.

navigate to git lfs download and install, mirgrate

on linux it's even more simple

sudo dnf install git-lfs

inside your repo, you need to add extension, which are to be tracked by lfs.

git lfs install
git lfs track "*.png"
git lfs track "*.jpg"
git lfs track "*.jpeg"
git lfs track "*.tiff"
git lfs track "*.pdf"
git lfs track "*.7z"
git lfs track "*.tar"
git lfs track "*.gz"
git lfs track "*.xls"
git lfs track "*.xlsm"
git lfs track "*.xlsx"
git lfs track "*.doc"
git lfs track "*.docx"
git lfs track "*.vsd"
git lfs track "*.vsdx"
git lfs track "*.vss"
git lfs track "*.vssx"
git lfs track "*.ppt"
git lfs track "*.pptx"
git lfs track "*.ipynb"
git lfs track "largefiles/*.xml"
git lfs track "largefiles/*.csv"

in case you cloned repository before having git lfs installed, files tracked by lfs will not be present in your repo, only a link will be there. just enter 2 commands to fix it.

git lfs fetch
git lfs checkout
