PyCharm Local History: Recover Uncommitted Edits Without Git

The uncommitted deletion problem

You spend twenty minutes cleaning up a module. You delete a helper function, save the file, run the tests, and then notice another function still calls the code you removed. You have not committed anything yet, so git checkout cannot rewind the change. Reopening the file from disk will not help because you already saved. This is the exact gap PyCharm's Local History is designed to cover.

How PyCharm's Local History journal works

Local History is a built-in journal that records snapshots of your files automatically. A snapshot is a recorded state of a file at a specific moment. PyCharm captures these snapshots when you save a file, when an external process modifies a file on disk, and when you perform version-control operations such as a commit. The snapshots are stored in the IDE's internal system folder, not inside your project directory, so they survive IDE restarts. They do not, however, travel with the project if you copy the folder to a different machine.

To inspect the journal, right-click a file or folder in the Project tool window and choose Local History > Show History. PyCharm opens a two-pane view. The left pane lists timestamped snapshots. The right pane shows a side-by-side diff—a line-by-line comparison—between the selected snapshot and the current file contents. From this view you can revert an entire file to a previous snapshot, or select individual changed blocks and restore only those lines.

Worked example: restoring a deleted block

Suppose you are refactoring invoices.py. You delete a calculate_tax_exemption block, save the file, and then discover that generate_invoice still references it. Because the change is uncommitted, your version-control system cannot help.

1. In the Project tool window, right-click invoices.py.
2. Select Local History > Show History. No special permissions are required beyond normal read/write access to the project directory.
3. In the left pane, choose the snapshot timestamp from just before your deletion.
4. In the diff pane on the right, locate the removed block. Use the revert arrow beside that block to restore only those lines, leaving the rest of your refactoring intact.
5. Save the file.

Check: Search the file for calculate_tax_exemption to confirm the block returned, then run your test suite. If the reference error is gone, the restoration worked.

Risk: If you select the wrong snapshot and revert the whole file, you will discard every edit made since that timestamp. Prefer block-level restoration unless you intend to lose all newer changes.

Retention limits and project-path binding

Local History is not a version control system (VCS). It has no branches, no remote synchronization, and no commit metadata. Storage is finite: PyCharm automatically purges the oldest snapshots based on a configured retention period—the length of time entries are kept before deletion. To review the setting, open Settings (or Preferences on macOS) and search for "Local History" under Appearance & Behavior. The exact menu path can vary by IDE version, so use the settings search box if the direct path differs.

History is tied to the project's absolute path on disk. If you manually move or rename the project folder, PyCharm may treat it as a new project and the old snapshots will not appear. Treat Local History as a short-term safety net for iterative work, and keep using Git or another VCS for durable history.

When Local History fits your workflow

Use Local History when you need to undo an accidental save, compare against a state from earlier in the same session, or recover a deleted block before you have committed. Do not rely on it across machines, after long idle periods, or as a substitute for pushing commits to a remote repository. For critical work, verify that the change exists both in Local History and in your VCS before you close the IDE.
