Settings & keep-time · Rules and safety floors
What is the "Hard floor" in Storage Studio's Rules settings?
Short answer: The hard floor stops Storage Studio automatically moving or deleting anything modified within the last 7 days (by default), whatever a rule says. Change it under Global overrides in Settings → Rules.
The hard floor is a safety net: Storage Studio will never automatically move or delete anything modified within this many days, whatever an individual rule says. The default is 7 days.
You'll find it under Global overrides in Settings → Rules as Hard floor — never act on anything younger than … days. If a rule's own age is lower, the floor wins.
You can lower it, but the app asks you to confirm first, because files you edited this week could then be moved. Only lower it if you understand that and have independent backups.
