How? Exactly how I did it in the following thread. I placed the result into a folder with some files inside it, but it would also be possible to zip up the folder into a single zip file, prior to encoding it, which would then be passed to the "decode" stage which reverses everything and puts the clipboard back the way it was. I thought that the base64 app would be able to handle folders. But now that I look into it, base64 can handle only files, (sadly) not folders. So maybe that would mean a few extra steps of work.
Now that I know how to save flavours in a clipboard, and now that I know that base64 doesn't support folders, I can see that it's not as easy as I thought. It might require a second line of code!
I see your point, but I believe there are ways around it, like I explained above.
