ASSOCIATING A FILE TYPE WITH AN APPLICATION IN A NETWORK STORAGE SERVICE

Techniques are described for associating file types with application in a network storage service. A user environment manager at the storage service receives a file identifier for a specific requested file from a user operating a computing device and obtains a file format type identifier associated with the file identifier from a data store for the file. The user environment manager determines a default application to open the specific requested file in response to matching an application ID (app ID) from a default "Open with" list contained in a user preferences store with a list of app IDs for installed applications that support the file format type. Once determined, the user environment manager opens the specific requested file from the data store utilizing the default application. In some implementations, the user environment manager presents a list of applications capable of opening a requested file.
