Systems and methods disclosed herein provide access to a data file stored at a remote data storage system. A user device can send a file access request, via a user interface provided by the remote storage server, to the application server to access a data file stored at the remote storage server. The application server can then optionally identify a relevant application for accessing the data file, and send, to the remote server, a metadata-and-content request relating to the data file. The metadata-and-content request includes version information of a previously cached version of the data file cached at the application server. When the cached version is not the latest version, the application server receives the latest version of the data file from the remote storage server. The latest version of the data file is then presented, via the relevant application on the application server, to the user device.
