Folder structures and network drives are how all company data is handled.

Eh, kinda of, but modern enterprise document storage is largely evolving away from it for general business users. I say this as an IT professional that has been an active consumer of the evolution over the last 25 years. Yes, SMB/CIFs/NFS shares still exist in the corporate enterprise, but modern enterprise systems are doing document storage more in Sharepoint, Google Drive, or even object form (storage buckets). All of these last three don't use a traditional file system where folder (directory really) navigation is a required skill.

This is especially true with Google drive. Yes, there are folders, but its equally likely that the file you need isn't even in your folders because its been shared to you by another user from one of their folders. Links, bookmarks, and free text file searches are often more useful for locating document that navigating a traditional directory tree. This is somewhat true in Sharepoint too.
