How long does the Bridge app keep Junk Yard scraps on my PC?
Short answer: You choose in Settings → Keep scraps for: 1 hour, 6 hours, 1 day, 3 days or 1 week, after which scraps expire automatically. Clear all empties the Junk Yard at once.
As long as you choose in Settings → Keep scraps for: 1 hour, 6 hours, 1 day, 3 days or 1 week. After that, a scrap expires on its own.
To clear everything sooner, use Clear all in the Junk Yard; right-click a single scrap to delete it. The All sources filter lets you see only what came from this PC or from your Mac.
On the Mac, the Junk Yard has its own keep-time setting.
