Desktop and filesystem access changedthird-party/claude-desktop/local-access

Nearest release: v2.1.277, published under an hour before upstream edited the page. Shown because the two are within 24 hours of each other. Nothing here says the release caused the edit.

Upstream edited this page at 18 Sep 2026 17:12 UTC, give or take a minute or two: the time comes from Anthropic’s own sitemap rather than from a commit. This site recorded the change at 28 Sep 2026 22:07 UTC.

1111Set [`allowedWorkspaceFolders`](/docs/third-party/claude-desktop/configuration#allowedworkspacefolders) in the managed configuration to restrict which paths users may attach as workspace folders. The [Configuration reference](/docs/third-party/claude-desktop/configuration) covers where the managed configuration lives on each platform and how to deploy it.

13| Value | Behavior |
14| ---------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
15| Unset | Unrestricted. Users can attach any folder they have OS-level access to, matching standard Claude Desktop. |
16| `["~/Documents/Claude", "/Volumes/Shared/Projects"]` | Users may attach only folders **inside** one of the listed roots. |
17| `[]` | No folders may be attached. The agent can still create files in its own sandbox scratch space, but cannot read or write the user's filesystem. |

1919A leading `~` expands to the user's home directory, so a single profile can express per-user roots like `~/Documents/Claude` across the fleet. A path may also reference one of a fixed set of environment-variable tokens, such as `%OneDrive%` or `%USERNAME%`, listed in the [configuration reference](/docs/third-party/claude-desktop/configuration#allowedworkspacefolders). An entry that references any other `%VAR%`, or one that is unset on the device, is ignored.

2121Each entry is either a plain path string or an object with these fields:

23| Field | Description |
24| ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
25| `path` | The folder path (required). Subfolders are included. |
26| `mode` | `rw` (the default) or `ro`. The agent can view and search a read-only folder but cannot modify it in Cowork. In Code sessions, read-only applies to Claude's file tools only; shell commands and [SSH remote sessions](/docs/third-party/claude-desktop/ssh-remote-sessions) do not enforce it. |
27| `isDefaultSelected` | When `true`, the folder appears already selected on the new-task page and skips the trust prompt. Users can remove it. |
