1. A system comprising:
one or more processors; and
a memory that stores one or more programs that are configured to be executed by the one or more processors, the one or more programs including instructions to perform actions that:
maintain a plurality of hashsets at a client device, wherein a hashset comprises a plurality of hash values of shared files of a directory of a remote file system, wherein each hashset is associated with a time point, wherein a hash value is associated with metadata of a shared file of the directory of the remote file system;
obtain from the remote file system, via a network protocol, metadata of each shared file of the directory of the remote file system, wherein the network protocol comprises a file transfer protocol that differs from a web Application Programming Interface (API) and has no support for API access;
compute a new hash value of a first shared file of the directory of the remote file system at a current time point t;
search the plurality of hashsets for a hash value of the first shared file matching the new hash value from a hashset of time point t−1 and from a hashset of time point t−2;
detect a change in the first shared file when the new hash value at time point t is not contained in the hashset of time point t−2 and is contained in the hashset of time point t−1;
upon detection of the change to the first shared file, set a trigger to a workflow engine indicating the change to the first shared file; and
upon receipt of the trigger by the workflow engine, initiate a specific workflow from pre-configured actions based on the changed first shared file, wherein the workflow is a series of automated operations to perform a task.
