Selective synchronization of content items in a content management system

1. A method comprising:

storing, at a client device, a local tree data structure representing content items in a file system on the client device, the content items are associated with a user account on a content management system;

storing, at the client device, a remote tree data structure representing a remote set of content items associated with the user account, the remote set of content items being stored at the content management system;

receiving, at the client device, a synchronization setting for a content item associated with the user account, the synchronization setting disabling local storage of the content item;

in response to the synchronization setting:

deleting a local copy of the content item from the client device;

removing, from the local tree data structure, a representation of the content item in the local tree data structure; and

adding, to the remote tree data structure, a hidden attribute in association with a representation of the content item on the remote tree data structure, the hidden attribute indicating that local storage of the content item has been disabled, whereby the content item is excluded from being stored on the client device as a result of a future synchronization while the hidden attribute remains associated with the representation of the content item in the remote tree.

2. The method of claim 1 , further comprising presenting, via a graphical user interface, the content items in the file system on the client device and one or more graphical control elements for selecting respective synchronization settings for the content items in the file system on the client device.

detecting an add operation at the client device, the add operation adding a second content item on the client device, the second content item being stored at a path associated with the representation of the content item and a remote copy of the content item;

determining that synchronization of the second content item at the client device would create a conflict with the remote copy of the content item based on the path comprising a same path for both the second content item and the remote copy of the content item;

in response to determining the conflict, modifying the path of the second content item on the client device to yield a second path; and

storing the second content item on the client device at the second path.

10. The method of claim 9 , further comprising:

adding a representation of the second content item to the local tree data structure, the representation of the second content item representing the second content item and associating the second content item with the second path; and

in response to adding the representation of the second content item to the local tree data structure, synchronizing the local tree data structure and the remote tree data structure, wherein synchronizing the local tree data structure and the remote tree data structure comprises adding a representation of the second content item to the remote tree data structure corresponding to a remote copy of the second content item.

11. The method of claim 10 , wherein the representation of the second content item on the remote tree data structure associates the remote copy of the second content item with the second path.

12. A non-transitory computer readable medium comprising instructions, the instructions, when executed by a client device, cause the client device to:

store a local tree data structure representing content items in a file system on the client device, the content items associated with a user account on a content management system;

store a remote tree data structure representing a remote set of content items associated with the user account, the remote set of content items being stored at the content management system;

receive a synchronization setting for a content item associated with the user account, the synchronization setting disabling local storage of the content item;

in response to the synchronization setting: delete a local copy of the content item;

remove, from the local tree data structure, a representation of the content item on the local tree data structure; and

add, to the remote tree data structure, a hidden attribute in association with a representation of the content item in the remote tree data structure, the hidden attribute indicating that local storage of the content item has been disabled, whereby the content item is excluded from being stored on the client device as a result of a future synchronization while the hidden attribute remains associated with the representation of the content item in the remote tree.

13. The non-transitory computer readable medium of claim 12 , wherein receiving the synchronization setting comprises receiving, via a graphical user interface on the computing device, user input identifying the synchronization setting.

14. The non-transitory computer readable medium of claim 12 , storing instructions which, when executed by the client device, cause the client device to:
