How long do forms stay in archive?

I have archived some forms in order to keep the list of the active forms lean.  However, I do not know how long forms stay in the archive folder.  Do they stay there until things are put in trash or do they automatically move to trash after a certain period of time?

I'm pretty sure that forms stay there until you unarchive them or delete.

So no need to worry about archived forms.

Please let us know if you have more questions.

Thank you.
