Is there a way to link the files that we have in our shared drive in our computers (not cloud-based) to NetSuite? The goal is to keep our files outside NetSuite, so that we won't exceed the storage limit and for compliance purposes (for government). The idea is to have a link in NS that our users can click to go to that file in the shared drive.

You're not going to have much fun with

file://

URIs (browser security reasons)

Hmmmm. Thank you. Is there any other alternative?

You might want to consider leveraging cloud-based storage using our eXtendFiles bundle. eXtendFiles has been a BFN SuiteApp since 2016 and can connect to a variety of cloud storage solutions. If you'd like to schedule a demo to see it in action, just let me know.
