Any method extension of class DocuWare.Platform.ServerClient.FileCabinetExtensions (Docuware.Platform.ServerClient.DotNet.dll) create a new stream for files (IFileUploadInfo) to upload to server but it never disposes after use.

This problem causes many errors after trying to manipulate file after send to docuware. Example: Send a big file to docuware and try to delete it after upload will cause an exception.
