Transferred files

[Furbanooo]

Hello everyone.
I'm a beginner in the WSL system and in the world of software engineering. I'm using kali Linux with the WSL2. I transferred some code files from a repo in windows to kali but I can't 'Git add' any of the transferred file to then commit. Meanwhile I've created a new Js file inside of kali and was able to 'Git add' that one.
Also while using vscode from that WSL kali I'm not able to save any changes inside of the transferred files.
I'll be grateful if anyone can help figure out what it is.
Thanks.
