I have searched on Google, and I have completed the following steps:

* Delete "all" activity history from the "Privacy" application.
* Remove the file "recently-used.xbel" from `~/.local/share`
* `$ nautilus -q`
* Remove the file "activity.sqlite" from `~/.local/share/zeitgeist`
* `$ zeitgeist-daemon --replace &`

I checked my "Recent" folder in between all of the above steps and none of them had any impact. I also tried:

* Remove all files with "sqlite" in the name from `~/.local/share/zeitgeist` (3 files:)
	+ activity.sqlite
	+ activity.sqlite-shm
	+ activity.sqlite-wal
* `$ zeitgeist-daemon --replace &`

None of the above had any impact on the contents of the "Recent" folder.

According to everything I've found, removing the file "recently-used.xbel" and restarting Nautilus should clear the "Recent" folder. Why isn't it working?
