Copy all lastly updated files into a single directory if the version control is horribly not done by git:

Instantiate a git repository (don't need to connect to any remote branch, do everything locally). Create a .sh file at the current directory, and paste:

#!/bin/bash

git add .
git status

updatedFiles=$(git status | awk '{print $2}' | grep -P "\..*$")

touch updates/update.txt
git status > updates/update.txt

for file in $updatedFiles
do
    cp --parents "$file" ./updates
    echo "copied $file to ./updates/$file"
done;

read -p "Press enter to exit"

mkdir updates and then run the bash script above. Files will be copied into updates directory, and we can manage it by date.
