## Used by methods

- [IRPCObjectOperations.DownloadFileWithDownloadKey](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCObjectOperations/DownloadFileWithDownloadKey/index.md): Not available over native gRPC: the server answers "Not implemented.". Used by the M-Files HTTP gateway.
- [IRPCObjectOperations.UploadTempFile](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCObjectOperations/UploadTempFile/index.md): Uploads a block of a file to a temporary upload session on the server. The upload can then be used as the content of a new object.
- [IRPCSearch.GetFacetValues](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCSearch/GetFacetValues/index.md): Retrieves the facet values for the documents that satisfy the specified search conditions.
- [IRPCSearch.GetFolderContents](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCSearch/GetFolderContents/index.md): Lists the contents of a view or a view level: subviews, grouping folders and objects.
- [IRPCSearch.GetFolderContentsOrDelta](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCSearch/GetFolderContentsOrDelta/index.md): Gets the contents of the specified folder, or a delta that indicates changes to document vault data since the logical timestamp known by the caller.
- [IRPCSearch.GetFolderObjectsCount](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCSearch/GetFolderObjectsCount/index.md): Gets the count of objects in the specified folder.
- [IRPCSearch.SearchObjects](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCSearch/SearchObjects/index.md): Searches the vault for objects that match the given conditions.
- [IRPCViews.DownloadFolderContentWithDownloadKey](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCViews/DownloadFolderContentWithDownloadKey/index.md): Not available: always fails with "Not implemented.".
