@arubislander Both of your answers are important to me. At first i only searched for an easy option to transfer files to and from my phone. The First Thing that comes to my mind is (S)FTP, when it comes to this topic. So i searched for exact that.
For SMB you have to configure more, but if it pops up in the File-Explorer after that, it is a even better solution.
Full Story is: I have a KeePass in my local-network which i want easy access to.On Android there is an App in which you can Sync your Keepass-Database via SFTP. But a mount of an SMB-Network-Drive would be closer to a "normal" Workflow on the System, i think.
In the Open-Store there is also a KeePass but it doesnt support SFTP right out of the Box - but shows the File-Explorer. So if i could mount via SMB i had my easy access.
Sorry for misleading Topic-Name.
