and wherein the request, received via the user interface associated with the first application on the user device, to open the document of the documents on the cloud computing service results in downloading and opening locally on the user device, by one of the plurality of document processing applications on the user device, a file that corresponds to the document of the documents on the cloud computing service. ### Claim 2 (depends on 1) The method of claim 1, wherein the second application obtains information identifying the one of the plurality of document processing applications, wherein the identifying information is created based on a contents file that stores a list of local application identifiers corresponding to the plurality of document processing applications that are installed on the user device. ### Claim 3 (depends on 1) The method of claim 1, wherein the one of the plurality of document processing applications opens the file locally based on a received message that comprises an application identifier associated with the second application. ### Claim 4 (depends on 1) The method of claim 1, further comprising generating a hash based on at least one pre-shared key to determine the user is authorized to access the file. ### Claim 5 (depends on 4) The method of claim 4, wherein the hash is computed based at least in part on at least one nonce. ### Claim 6 (depends on 1) The method of claim 1, wherein the request to open the document comprises a user identifier. ### Claim 7 (depends on 2) The method of claim 2, further comprising selecting the one of the plurality of document processing applications by the first application using the list of local application identifiers. ### Claim 8 A system comprising: a memory; and a processing device, coupled to the memory, to: present, using a first application hosted by a user device, a user interface associated with the first application, the user interface permitting a user to interact with documents on a cloud computing service; receive, via the user interface associated with the first application on the user device, a request to open a document of the documents on the cloud computing service; authenticate the user with the cloud computing service and determining that the user is authorized to access the document; and communicate, using the first application on the user device, the request to open the document of the documents on the cloud computing service to a second application hosted by the user device, wherein the second application on the user device is a local application different from the first application, wherein the second application has access to local information about a plurality of document processing applications that are installed on the user device to allow a user of the user device to create, open and edit a plurality of local files of different types on the user device, each of the plurality of document processing applications corresponding to a distinct type of the different types of local files; and wherein the request, received via the user interface associated with the first application, to open the document of the documents on the cloud computing service results in downloading and opening locally on the user device, by one of the plurality of document processing applications on the user device, a file that corresponds to the document of the documents on the cloud computing service. ### Claim 9 (depends on 8) The system of claim 8, wherein the second application obtains information identifying the one of the plurality of document processing applications, wherein the identifying information is created based on a contents file that stores a list of local application identifiers corresponding to the plurality of document processing applications that are installed on the user device. ### Claim 10 (depends on 8) The system of claim 8, wherein the one of the plurality of document processing applications opens the file locally based on a received message that comprises an application identifier associated with the second application. ### Claim 11 (depends on 8) The system of claim 8, wherein the processing device is further to generate a hash based on at least one pre-shared key to determine the user is authorized to access the file. ### Claim 12 (depends on 11) The system of claim 11, wherein the hash is computed based at least in part on at least one nonce. ### Claim 13 (depends on 8) The system of claim 8, wherein the request to open the document comprises a user identifier. ### Claim 14 A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising: presenting, by a first application hosted by a user device, a user interface associated with the first application, the user interface permitting a user to interact with documents on a cloud computing service; receiving, by the first application on the user device and via the user interface associated with the first application on the user device, a request to open a document of the documents on the cloud computing service; authenticating the user with the cloud computing service and determining that the user is authorized to access the document; and communicating, by the first application on the user device, the request to open the document of the documents on the cloud computing service to a second application hosted by the user device, wherein the second application on the user device is a local application different from the first application, wherein the second application has access to local information about a plurality of document processing applications that are installed on the user device to allow a user of the user device to create, open and edit a plurality of local files of different types on the user device, each of the plurality of document processing applications corresponding to a distinct type of the different types of local files; and wherein the request, received via the user interface associated with the first application on the user device, to open the document of the documents on the cloud computing service results in downloading and opening locally on the user device, by one of the plurality of document processing applications on the user device, a file that corresponds to the document of the documents on the cloud computing service. ### Claim 15 (depends on 14) The non-transitory computer readable medium of claim 14, wherein the second application obtains information identifying the one of the plurality of document processing applications, wherein the identifying information is created based on a contents file that stores a list of local application identifiers corresponding to the plurality of document processing applications that are installed on the user device. ### Claim 16 (depends on 14) The non-transitory computer readable medium of claim 14, wherein the one of the plurality of document processing applications opens the file locally based on a received message that comprises an application identifier associated with the second application. ### Claim 17 (depends on 14) The non-transitory computer readable medium of claim 14, wherein the operations further comprise generating a hash based on at least one pre-shared key to determine the user is authorized to access the file. ### Claim 18 (depends on 17) The non-transitory computer readable medium of claim 17, wherein the hash is computed based at least in part on at least one nonce. ### Claim 19 (depends on 14) The non-transitory computer readable medium of claim 14, wherein the request to open the document comprises a user identifier. ### Claim 20 (depends on 15) The non-transitory computer readable medium of claim 15, wherein the operations further comprise selecting the one of the plurality of document processing applications by the first application using the list of local application identifiers.
