## Interface ISimpleFileStorageAppSoap

- All Known Implementing Classes:
    SimpleFileStorageAppSoapMockStub, SimpleFileStorageAppSoapStub

      public interface ISimpleFileStorageAppSoap

  Provides SOAP web service for uploading/downloading files. Uploaded files are assigned a "temporary file storage id" which must be used within the SOAP session to create a document/FRS file/etc. Otherwise, the uploaded file is simply discarded. This service is primarily meant for clients which are unable to use SOAP file attachments for uploading/downloading files. Uploading/downloading files as attachments is much more efficient than returning them in memory. The "FileStorageApp" service provides support for uploading/downloading files as attachments.
