Abstract: Aspects of the subject technology provide for integration between a messaging system and a collaborative application. A messaging system may receive, via user input, an instruction to create a message thread with a plurality of user accounts. The message thread may include a document link associated with a collaborative application. The messaging system may generate, for each of the user accounts, an obfuscated identifier associated with that user account and a document link. The messaging system may provide the obfuscated identifiers to the collaborative application. An initial message exchanged between the plurality of user accounts with the document link in the message thread may establish, for the collaborative application, the obfuscated identifiers that will be associated with the document link.

Abstract: This application relates to a technique that enables a software application to access files at a computing device while enforcing privacy measures. The technique includes a file browser that can act on behalf of a software application to communicate a user file selection to a relevant file access service. While operating in a sandboxed mode, the file browser can communicate the user file selection while the software application is unaware of the file browser's activities. The file browser can display a set of files that are available for user selection using an enumeration logic that is distinct from an enumeration logic implemented by either the software application or the relevant file access service. When a user file selection is detected, the file browser can assist the software application in receiving a secure URL to enable the software application to directly-access the file associated with the user file selection.

Abstract: This application relates to techniques for dynamically displaying relevant files for selection by a user at a computing device. The technique can provide a file browser that, upon detection of a file selection, performs enumeration procedures on a file access service that provides the file. The results of the enumeration procedures are utilized by a file provider daemon to synchronize locally cached files that fall under the domain of at least one file access service. Using key property data identified by the file provider daemon, a file access service responsible for a locally cached file can communicate an updated version of the locally cached for receipt by the file browser. The file browser can then display the updated version of the locally cached file within a pre-defined category for quick access by the user.
