At home my PCs have CIFS/SMB shared folders, it’s handy and simple to use. However I can’t find an Android app capable of browsing these shares.
There’s Android Samba client and CIFS Document provider on F-droid but both require to know the exact IP and path, you can not just browse the network like on a PC.
Cx File Explorer supports SMB, FTP, SFTP, and WebDAV remotes out of the box. There is an option to browse the local network.
I like CX File Explorer too. And I appreciate that there are no ads! I wish the dev would make dark mode available though.
