Deleting and Re-Uploading Files in Git Without Losing Your Mind
At some point you’ll need to replace old files with a new version. In Git, this is simple in theory and confusing in practice, especially the first time you do it.
The Basic Steps
From inside your project folder (see directory confusion guide if you’re not sure you’re in the right place):
1. Stage the deletion of all tracked files:
git rm -r .2. Commit the deletion:
git commit -m "Delete old files"3. Add your new files, then stage and commit:
git add .
git commit -m "Add new version"4. Push:
git push origin mainWhere This Goes Wrong
“I deleted everything — why are the old files still on GitHub?”
Deleting locally and deleting on GitHub are two separate events. Nothing changes on GitHub until you actually push.
“These look like the same files — did anything actually change?” Identical filenames don’t prove identical content. Click into the specific commit on GitHub and look at the diff — the only way to know, rather than guess from file names alone.
“Git won’t let me push — it says the remote has work I don’t have locally.” This happens when GitHub has commits your local copy doesn’t know about. Git is protecting you from silently overwriting something. If you’re certain your local version is the one you want to keep:
git push --force origin mainUse this carefully. Force-pushing overwrites GitHub with exactly what you have locally, no merging. On a personal solo project, that’s usually fine. On anything shared, it can erase someone else’s work.
A Faster Alternative for Big Replacements
If you’re replacing most or all of a project at once, it’s sometimes easier to skip the incremental dance entirely and re-upload the whole folder through GitHub’s website. → Drag-and-Drop vs Git
The Takeaway
Git doesn’t lie to you, but it also doesn’t over-explain itself. “Deleted” only means deleted-and-pushed. “Looks the same” isn’t proof of anything — the commit diff is. And a rejected push isn’t Git being difficult; it’s double-checking you actually mean to overwrite something.
