QNAP/Home

The folder named "home" just a default name when the share folder name is not specified.

Each separate user will see their own unique "home" share when they're connected.

By default you get a homes share which contains all the individual "home" shares, one for each user. These are in addition to the shares you create yourself. (You can create as many of your own shares as you like and name them how you like).

Login
As long as PC username/password pair is identical to your NAS username/password pair, you will be able to access "\\\home" from your PC without being asked to re-provide your login credentials every time you access your "home" share.

Technical
The "home" share is a virtual share. It points to /share/homes/username for every user that connects to your NAS. Your Windows users on your network can connect to "\\NAS\home" in Windows Explorer to access their $HOME directory on the NAS. (They can also connect to \\NAS\username to get to the same place).

Admin-related
After the user connects to their \\nas\home -folder, the "homes" folder will be created and visible from web file manager.
