This quick Ableton Live walkthrough shows how to reload a saved preset from your Collections browser, simply by dragging it from the panel into an empty spot in your Session view. It's the fastest way to bring back a previously tagged sound, like a saved Chords preset, without digging through folders.
It also covers how to find where Live actually stores your User Library on disk. Head into Preferences, then the Library tab, and check Content/Locations to see the current directory path.
If you've moved your files or switched drives, the same screen lets you relocate the library. Click Browse, point Live to the new folder location, and confirm with OK so all your saved presets and sounds stay linked correctly.
