# Give Claude access to one folder, and undo changes

> To give Claude access to one folder inside 1folder, choose Only the folders I pick on the Allow page, select that folder and choose view or view and edit. ChatGPT can too, on Business, Enterprise and Edu. This controls files in 1folder, not folders on your computer; remove a connection to cut its access at once.

*Picture: 1folder’s Allow page: “Claude wants to use your 1folder”, with Only the folders I pick in Client work and View and edit chosen, then Allow. The versions of Acorn proposal: Shortened the introduction (Claude, today); Approved scope and price (you, Monday).* Pick a folder on 1folder’s Allow page, then use file versions to inspect and undo changes an AI app saves there.

## Allow only the folder the task needs

1. **Put the relevant work in a dedicated folder.** Create an Acorn brief folder in 1folder and add the source notes and proposal the task needs. Keep other clients’ work outside that folder. Naming a folder in a request is helpful; choosing the allowed folders is what limits the connection.
2. **Connect Claude and pick that folder.** Add https://1folderapp.com/mcp as a [custom connector in Claude](https://1folderapp.com/integrations/claude-connectors.md), sign in and select Only the folders I pick on the Allow page. Choose Acorn brief rather than the whole space.

3. **Choose the level for the job.** Use view when Claude should read and answer. Choose view and edit when it should create or update files in the allowed folder. You can give ChatGPT access to a folder through [its own connection](https://1folderapp.com/integrations/chatgpt-connectors.md) the same way, on Business, Enterprise or Edu; on Pro it can only read.

   *Picture: In Claude, you type: “Read the notes in Acorn brief in 1folder. Update only the introduction of Acorn proposal, keeping the agreed scope and price.”*
4. **Review changes and remove access when finished.** Open the saved file and compare its versions. Undo an unwanted edit, or everything an AI app changed in one go when that is the correction you intend. Remove the app in Connections to stop further access.

## Folder access and undo solve different problems

Allowed folders limit what the connection can reach. View or view and edit determines whether it can save work there. Version history records content changes already made. Removing the connection stops future access; it does not undo past edits or retract information the app already read.

Even with edit access, an AI app cannot [make a file public](https://1folderapp.com/how-to/share-files-with-clients.md), lock or unlock it, or delete it for good. It can move files to Trash, where they remain for 30 days. Every saved content change is a version marked with the person or AI app that made it.

## How to undo Claude changes in 1folder

Suppose shortening the proposal also removed the approved delivery date. Open the file’s versions and compare the current version with the approved one. Undo the unwanted change, then ask for a narrower revision. If several files were affected, review what changed before choosing to undo everything that app did in one go.

Free shows 30 days of version history; Pro and Team show one year. Older versions are hidden, never deleted. This history applies to work saved in 1folder. It does not roll back a local checkout, a [Google Doc](https://1folderapp.com/how-to/can-claude-edit-google-docs.md) or files deleted elsewhere.

## “Claude deleted my files”: recovery on a computer

- Pause further edits and identify the exact paths and where the session ran. Keep copies of current work before attempting a restore.
- For Claude Code edits, inspect /rewind. Anthropic says checkpoints track its file-editing tools, but shell-command changes are not tracked; a shell deletion may therefore have no checkpoint to restore.
- For a file already in Git history, identify the version you need and review existing work before restoring only that path. Git documents the form git restore --source=<known-good-commit> -- path/to/file; it replaces that path with the chosen source.
- If the file was never tracked and no checkpoint contains it, look for an existing backup or another saved copy. 1folder cannot recover a local file it never received.

## Make the allowed task specific

- In Claude: “Read Acorn proposal in my Acorn brief folder in 1folder. Shorten only the introduction to 100 words. Preserve the agreed scope, fee, delivery date and all other sections. Update the same file and return its private link.”
- In ChatGPT: “Read the restored Acorn proposal in 1folder. List the agreed scope, fee and delivery date without editing the file. Tell me if any of those details are missing.”

## Questions

### Does this give Claude access to a folder on my laptop?

No. This page’s connection settings control folders inside 1folder. Local Claude Code permissions and local file recovery are separate.

### Can I give ChatGPT access to just one folder too?

Yes. In its 1folder connection, pick the allowed folders and choose view or view and edit. Other connections the app has are separate and are not narrowed by this setting.

### Can an AI permanently delete my files in 1folder?

No. An AI app cannot delete for good. It can move a file to Trash for 30 days. That rule applies inside 1folder, not to a computer or another service.

### Can 1folder undo files Claude Code deleted locally?

No. Check Claude Code checkpoints for tracked edits, Git history for committed files and your own saved copies or backups. 1folder can undo only work saved in 1folder.

### Does removing the connection undo its changes?

No. It cuts access at once. Review versions and undo changes separately if you need to restore earlier work.
