Export to USB to include buttons

How to export to USB so that buttons are also included.
e.g. I have a set shooting time button (.dcf-file)

When I export to USB, this button will not show up when running DO from USB, i.e.
it is not included in the exported version.

TIA

Why is it in a .DCF file and not on a toolbar / menu / hotkey?

(You only usually use those to share buttons with other people or run buttons from outside of Opus.)

You need to provide more info about where these DCF files are located in your normal running config... It's not really a normal Opus configuration to have .DCF button files laying around in a way that can be "used". They're normally part of a TOOLBAR right?

So, I guess I won't bother asking why you don't just have this "button-file" added to a toolbar somewhere... and suggest instead that you might want to consider putting things you want to be saved as part of your Opus configuration Backup (including USB exports) in a Scripts folder you can create under /dopusdata. I don't recall this being documented anywhere, but arbitrary contents of the Scripts folder will be backed up and exported along with the Opus specific stuff. I've got various scripts, tools, and alternate config files stored under mine for quite some time now.

Ok, I can't resist....... why don't you just have this "button-file" added to a toolbar......?

EDIT NOTE: Leo posted his after I started writing mine...

Remark: Scripts and its subfolders are included in backup/restore, but subfolders are not copy when exporting (you need to copy them manually).

Hmm... right you are. Guess I've not noticed that as I generally don't update my USB exports directly from Opus Export to USB function, but rather a separate button copy of select contents from my OCB file. Sorry bout that.

Suggestion still stands to use the Scripts folder for files... and also still stands about why/how flat .DCF button files are being used without a toolbar.
