Deleting the .git folder may cause problems in your git repository. If you want to delete all your commit history but keep the code in its current state, it is very safe to do it as in the following:
Checkout
git checkout --orphan latest_branch
Add all the files
git add -A
Commit the changes
git commit -am "commit message"
Delete the branch
it branch -D master
Rename the current branch to master
git branch -m master
Finally, force update your repository
git push -f origin master
