Git rename from index.lock to index failed

Question

Using the GitHub Windows client I did a sync to pull remote changes to my local machine, but before finishing the sync, I ran out of disk space and the sync failed.

Answer 1

I removed index and index.lock (in the .git folder) and ran git checkout . to undo the changes and resolved, but if I wanted to commit the changes I would have run git add -A after git commit -m "description"
