How to connect Appian with NAS(Network-Attached Storage).

The short answer is it's not in the product right now to mount a network drive.

Let's approach this more from your business requirements use case and less from the functional perspective of "connect to NAS".

Which direction should files flow; into Appian, out to the NAS or both?  Why?  What are the files? What is the use case?
Who benefits?  Is this for the business or for IT operations and maintenance?  

HI Robert,

We also have a similar requirement to allow users to download files from a NAS location.

The files in the NAS are due to the older version of the application which we have no migrated to Appian.

Since the number of files are too many and it would cost disk space to upload them on Appian document management system we are exploring a way to allow users to download files from NAS for any historical records that we have migrated from the old system.

If you are trying to connect from a cloud site directly to a NAS, it can't be done and most likely will not be added to the product. Here are some possible workarounds:

• Move the files to a location that Appian can access over a RESTful service, like S3
• Stand up a server to serve the files from your infrastructure, something like a WebDAV server: https://en.wikipedia.org/wiki/WebDAV
• Set up an SFTP server and access the files via the SFTP plugin
