Tencent Cloud’s object storage.

Shared code path Same code path as a verified service; endpoint unverified

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

Limits

What Tencent Cloud COS cannot do, read from the app's own service_traits() — the same answer its connection picker shows before you connect, not a judgement typed onto this page.

Prefixes, not directories

There are no real directories in this store — a “folder” is a shared prefix on the object keys. Making one writes a zero-byte marker object so the empty folder you just created is still there when you look again; a folder that only ever existed because files were under it has no marker, and goes when its last file goes. Anything that depends on an empty directory persisting has to know that.

A move is a copy, then a delete

This service has no server-side rename, so renaming or moving a file copies the bytes to the new name and only then deletes the old one — that order, so an interrupted move leaves your file where it was rather than nowhere. What it costs is a full transfer of the bytes, which is worth knowing before you drag a large folder. On this store a folder move is refused as a single operation and done file by file, because moving the one key that names the folder would leave everything under it orphaned.

The engineering ledger does not list Tencent Cloud COS 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

No lane yet. No server has been stood up to run the corpus against this service, so there is no record to publish. That is the honest answer, not a pending one. Every service’s standing, side by side.
