Howto delete old repositories completely, including cache files?

[goebbe]

When testing vykar I sometimes find myself creating new test-repositories - and I want to get rid of old repositories.

• On the (backup) server side, I typically just delete the repository-folder.

  • Is this sufficient?

• On the client side, are there any steps, that should / could be done, e.g. to clean old files from the cache?

I am asking, since some months ago I discovered large amounts of old cache files (several GB) lurking in ~.cache
from old, deleted repositories (from another backup program).

If you want to remove an old repository completely, deleting it from GitHub is only part of the cleanup.

Delete the repository on GitHub
Go to Settings → General → Danger Zone → Delete this repository.
Remove the local repository
Delete the project folder from your computer if you no longer need it.
Remove Git metadata
If you're keeping the project files but don't want it to remain a Git repository, remove the .git folder.
Clear cached credentials if necessary
Remove saved GitHub credentials/tokens from your system if the repository contained sensitive information.

Important: GitHub repository deletion does not automatically remove copies from existing clones, forks, or cached data elsewhere. If secrets were committed, revoke/rotate them rather than relying on deletion alone.

@ArfaMunam47 Thanks a lot for your answer!
After initial confusion and reading your answer a second time, I realised that there must be a misunderstanding.
My original questions / discussion was about Vykars "backup-repositories" - and not about Vykars github repository.
