System and method for preventing duplicate file uploads in a synchronized content management system

摘要

A method and system for preventing duplicate file uploads in a remote content management system is described. The user device receives a hash value list associated with the files stored in the remote content management system. The user device calculates a hash value associated with new files to be uploaded. The system then compares the hash value(s) associated with the new file(s) to be uploaded with the hash value list received from the remote file storage system. If the hash values of any of the new files to be uploaded match a hash value on the hash value list, then the system prevents the new files from being uploaded to the remote file storage system.

主权项

1. A computer-implemented method of preventing duplicate files in an account on a content management system that is associated with a particular user, comprising:
maintaining, by at least one server, a hash value list, each of the hash values on the list corresponding to a respective file that has been received by the at least one server for storage within the account; enabling an upload of a file from a client device to the at least one server for storage within the account; at least partially in response to receiving the file, calculating a hash value for the file; determining whether the calculated hash value for the file is on the hash value list maintained by the at least one server; at least partially in response to determining that the calculated hash value is not included in the hash value list: creating an updated hash value list by adding the calculated hash value to the hash value list, and storing the uploaded file in the account.
