To increase the file transfer speed for the shared drive, you should:

1. Configure the bandwidth settings: Set data transfer rate limits for local networks or specific sending/receiving computers.
2. Change the network type: Choose a network type from the list of network types regularly used to transfer files.
3. Clean up outdated files: Remove large files from the shared drive that are larger than what users need to access frequently.
4. Re-access files: Reconnect the shared drive to improve network performance.
