Local folder
Not a remote — a folder on your own disk, mounted through the same volume stack.
Not yet tested live Compile-verified; no live server reached yet
What Mountit does with it
- Mount
- Read and write, in Finder
- Offline cache
- Metadata cache, read-ahead and write-back — the same volume stack as every other service
- Encryption layer
- Available on this connection: client-side, rclone-compatible crypt over the data before it leaves your Mac
- Editions
- Both. Either edition mounts it through File Provider, so it appears in Finder — and, on Standard, in the Files app on iPad and Vision Pro
The engineering ledger does not list Local folder among the
services run against a real server, so this page does not claim it was. That is
read out of docs/BACKEND-COVERAGE.md in the app repository when
this site is built — the build fails rather than let this page claim more than
the ledger does.
The conformance record
Blocked by a finding. A lane ran and 4 findings stand between this service and a clean record. They are the return on running the corpus, and they are published rather than filtered. Every service’s standing, side by side.
Being mounted once is the floor. The conformance harness runs the same
corpus of assertions at every backend — must for the contract the
volume layer relies on, should for a well-behaved server, and probe for observations that become capability data — and commits
the verdicts as a file. These numbers are read out of that file.
A failure here is a finding about this protocol, not a broken test. They are published rather than filtered because a page that showed only the green ones would be worth nothing.
| Lane | Run | Must | Should | Probe |
|---|---|---|---|---|
| local-folder | 2026-09-01 | 61 passed, 4 failed | 17 passed, 8 failed, 3 skipped | 25 passed, 1 failed, 4 skipped |
- local-folder — 123 assertions. 4 assertions tagged
mustfailed. 2 capabilities the backend claimed were contradicted by what the server actually did. On the harness's own rule — nomustfailure and no capability disproved — this lane does not by itself promote the service.
Local folder questions
Can Mountit mount Local folder?
Yes — Local folder is one of the 38 services selectable in the app. It mounts read-write, with the same cache, read-ahead and write-back as every other service.
What we will not do is claim it works before it does: this page carries the ledger’s evidence level for Local folder, and it changes the day the evidence does.
Which edition do I need?
Either — this service is in both editions. The difference is the surrounding app, not the protocol: Mountit Pro is the unsandboxed build with the block protocols; Standard is the Mac App Store build, and on iPad and Vision Pro every service appears in the Files app. Both mount this service through File Provider.
Why would I mount a local folder?
Two honest reasons. It is how you use the encryption layer — an encrypted view of a folder you sync by other means — and it is how the composition layers are tested. As a plain mount it gives you nothing Finder does not.
