Hi @sangto2906 !
I just pushed a new feature to vangelis (testing) branch. It’s a file browser that allows full access to zynthian’s directory tree, including soudnfont locations, user presets, captures, neural models, config files, etc.
After updating (vangelis) you will find a link to this filebrowser in the webconf’s system menu:
by clicking the link you will access the file browser, like this:
Enjoy!
