Vlad, all you had to say was the command line is done from the server not filerun.

Anyone searching the forum would have had the answer from then on and not wasted your time anymore.
The car manufacturer prints manuals that say where the jack and crank are, even how to use them.

Having said that, FileRun is a great program and thanks for your help,

well if I knew who to ask I wouldn't ask here... Pointing me to what to search for in google (because I did before asking here and didn't find any help) would have taken you less time than typing you don't want to answer. It might be basic for you but none of it is explained in your guide.
And if you don't want to answer that as it's too basic you should put in your forum a guideline saying that if you don't know how to send commands to your server you shouldn't use filerun, nor post any questions about it.
Of course after precising that /cron is a folder of commands for your server.
thanks so much and sorry for not being educated enough.

Thanks Vlad, lucky for me this one wasn't too basic, yet everyone who knew the answer would probably think it was, cheers.

So what is the metadata box that is editable for ?   folder>more options>metadata

sorry but how and where do you execute that command line ?

Hey Vlad, not working, I've tried a simple README.txt then without the txt extension, nothing shows up on the right panel other than number of files in the folder
There's a very brief "reading metadata" that disappears and doesn't show the saved metadata.

Now that I've run "index all files" the audio folder is appropriately filled, sorry for the question. ANSWERED ;)
