File-level commenting

A non-transitory computer-readable storage medium storing instructions that, when executed by at least one processor, cause a computing device to:

• receive a comment to a content item stored in an account with an online content management system, the comment being received through an application programming interface (API) provided by the online content management system, with the content item being accessible via the account by at least two computing devices, and wherein a copy of the content item is stored locally on the at least two computing devices;
• assign the comment to the content item, wherein the content item is synchronized with the at least two computing devices;
• and
• cause the comment to be synchronized with the at least two computing devices, wherein synchronizing the comment does not alter data in the content item stored on the at least two computing devices.

A computing system, comprising:

• at least one processor;
• and
• memory including instructions that, when executed by the processor, cause the computing system to:
• provide a content item for display on a first computing device, the content item being viewable between the first computing device and at least one second computing device through an account with an online content management system, with the account being accessible via the first computing device and the at least one second computing device;
• receive a comment to the content item, the comment being received through an application programming interface (API) provided by the online content management system;
• and
• cause the comment to be synchronized with the first computing device and the at least one second computing device, wherein the comment is synchronized and attached to a copy of the content item stored locally on both the first computing device and the at least one second computing device, and wherein synchronizing the comment does not alter data in the content item stored on either the first computing device or the at least one second computing device.
