How to upload lua file?

Sorry for all the questions but again I am new to AltUI and didn’t see a solution browsing the threads and searching. It isn’t obvious to me IF I can upload lua files to my Vera 3 using AltUI. Using the UI5 user interface I can do that thru the Develop Apps Tab.

nope, ALTUI does not offer that functionality, it has to be done the classic way ( UI5 or UI7 develop app tab )
