Creating a new Object in VAF Using a Template Without Downloading The File

Creating an object from a template simply means copying the template object (files and metadata) and removing the "is template" property. There's a sample on copying objects in the developer portal.

Sorry I wasn't very clear in my first question... Is there a way to do it without downloading the files? Would M-Files approve an application that downloads the files to a local location for a public cloud environment? I've already written code to do this using a downloaded file but was hoping to avoid downloading the file to work better in cloud environments.

I have looked at the following:

The primary concern with files being "downloaded" in vault apps is them staying around after they've been finished with.  Your code should be written in such a way that any temporary files that are created are destroyed regardless of whether the code succeeds or fails.

To be clear (I'm sure you know this, but just for the benefit of others): when I use the term "download" in the context of the vault application I mean to transfer the file out of the vault and into temporary storage on the M-Files server.

Going back to your core point though: no, you will need to retrieve a copy of the file to subsequently use when you create the new object.  In the cloud you should use the temporary folder that .NET gives you access to (Path.GetTempPath()) for your files.  And, again, make sure your code is written in such a way that the files do not continue to reside on disk, even in error situations.
