6. The method of claim 1 , comprising:

generating a prompt for the user account of the client device, the prompt requesting user input to modify the symbolic link to preserve its functionality after the synchronization.

7. The method of claim 1 , further comprising:

determining that a user account associated with another client device of the one or more other client devices is configured to omit synchronization of the content item; and

generating prompt for the user account associated with the another client device to permit synchronization of the content item.

8. A non-transitory computer readable medium comprising instructions, the instructions, when executed by one or more processors, cause a content management system to:

receive, from a client device, one or more synchronization operations for synchronizing one or more content items on the content management system and to correspond to one or more content items on the client device based on changes to the one or more content items at the client device, the one or more content items being associated with a user account registered at the content management system;

determine that a content item of the one or more synchronization operations comprises a symbolic link including an absolute path to a target content item on the client device, wherein the symbolic link is shared between a plurality of user accounts;

determine that the absolute path to the target content item in the symbolic link is invalid at one or more other client devices that receive the content item through a respective synchronization operation with the content management system because the target content item resides in a location that is not accessible to at least one of the plurality of user accounts associated with the one or more other client devices, wherein the absolute path is valid at the client device;

modify the absolute path of the symbolic link at the one or more other client devices to be a shortened relative path valid for the one or more other client devices to yield the modified symbolic link that is valid at the one or more other client devices;

receive a modification to the content item from one of the one or more other client devices; and

synchronize, by the content management system, the modification of the content item according to the modified symbolic link as part of the operation associated with the one or more synchronization operations.

9. The non-transitory computer readable medium of claim 8 , storing instructions which, when executed by the one or more processors, cause the content management system to:

determine that the absolute path to the target content item in the symbolic link is invalid at one or more devices that receive the content item through the respective synchronization operation with the content management system; and

in response to determining that the absolute path is invalid at the one or more devices, determine one or more reasons why the absolute path is invalid at the one or more devices.

10. The non-transitory computer readable medium of claim 9 , wherein determining that the absolute path is invalid at the one or more devices that receive the content item through the respective synchronization operation with the content management system and determining the one or more reasons comprise:

determining that the symbolic link is shared between the plurality of user accounts registered at the content management system; and

determining that the target content item resides in a location that is not accessible to at least one of the plurality of user accounts.

11. The non-transitory computer readable medium of claim 10 , storing instructions which, when executed by the one or more processors, cause the content management system to:

after determining that the target content item resides in the location that is not accessible to the at least one of the plurality of user accounts, notify the user account that the at least one of the plurality of user accounts does not have access to the target content item;

receive authorization to grant the at least one of the plurality of user accounts access to the target content item; and

based on the authorization:

grant the at least one of the plurality of user accounts access to the target content item; and

synchronize the target content item with one or more respective devices associated with the at least one of the plurality of user accounts.
