Files

Where: iPhone → Settings → Files. Mac → Settings → Files.

The screen shows a Storage meter — how much of your plan's space the files take, how many there are and what is left, turning orange at 90% and red when full — and carries one switch.

• Delete files when done (on by default) — a task's files are deleted 48 hours after it is marked done. The task, its notes and its links stay; only the stored bytes go. Tidying runs in the background about once a day, so a file can outlive the window by a little, and moving a task out of Done before then keeps its files.
• Links are never touched. They cost nothing and always stay.

Limits. 100 MB for the whole account on Free, 5 GB with Pro; an upload that would go over is refused and offers the upgrade. 25 MB per file after compression. The apps compress before uploading: images are scaled to 2048 px on the longest edge and re-encoded, video is re-exported at 720p, anything else goes up as it is — and is refused rather than silently mangled if it is over. An agent sending bytes inline is capped at 8 MB; bigger files go through a source_url for Cotask to download.

Reads are public by design. Every file gets a long, unguessable URL that needs no credentials, so an agent handed a task — or a webhook receiving one — can fetch the file with nothing to configure. Nothing is listable: reaching a file means already knowing the whole path. Removing an attachment through the API deletes the stored file too.
