Every week someone emails us the same problem. They bought a pack, dragged the files somewhere that looked right, and Serum 2 shows nothing. Nine times out of ten the fix is boring: the files landed outside the Serum 2 preset folder, so the browser never saw them.
So let’s settle it once. In this guide I’ll give you the exact default paths on Mac and Windows, show you how to move the whole library to another drive, and explain why presets sometimes disappear after an update.
I run Monosounds.studio and we’ve shipped Serum packs since 2022. Folder paths are our single biggest support topic. This is everything I tell people, in one place.
Serum 2 Preset Folder: The Default Locations
Serum 2 keeps all user content inside one parent folder called Serum 2 Presets. Presets, wavetables, noises, samples – everything lives in subfolders under that one folder. Know where it is and every install problem gets easy.
Here are the default paths:
| Content | Windows | Mac |
|---|---|---|
| Main library | C:UsersYOUDocumentsXferSerum 2 Presets |
~/Library/Audio/Presets/Xfer Records/Serum 2 Presets |
| Your presets | ...PresetsUser |
.../Presets/User |
| Wavetables | ...TablesUser |
.../Tables/User |
| Noises | ...NoisesUser |
.../Noises/User |
| Samples | ...Samples |
.../Samples |
Two gotchas worth calling out. On Mac, ~/Library is hidden by default. In Finder, hit Cmd+Shift+G and paste the path, or hold Option while opening the Go menu and Library appears.
On Windows, watch out for OneDrive. If it syncs your Documents folder, the real path becomes C:UsersYOUOneDriveDocumentsXferSerum 2 Presets. People install packs into the non-OneDrive Documents folder and wonder why nothing shows up. I’ve seen this exact issue dozens of times.
The Fastest Way to Find the Folder
Don’t hunt through Explorer or Finder at all. Open Serum 2, go to the Menu tab, and use the option that shows the presets folder on disk. It opens the Serum 2 preset folder instantly, custom path or not. I use this daily and haven’t typed the path by hand in months.
That same Menu tab has Import Preset Pack, which handles .SerumPack files and puts everything where it belongs automatically. If your pack came in that format, use it and skip the manual copying entirely. We covered both methods step by step in our full Serum 2 preset install guide.
For loose preset files, the rule is simple: they go into Presets/User, and subfolders are supported. All patches in our Serum 2 preset bundles ship in named subfolders, so you drop the whole thing into User and the browser mirrors that structure. If your User folder is already a mess, here’s how I’d organize it before it gets worse.
How to Change the Library Location
Serum 2 doesn’t force you to keep the library on your system drive. This matters more than it used to, because Serum 2 presets can reference samples and multisamples – a big library eats real disk space now.
My studio machine keeps the library on a second SSD. Here’s the move that has never failed me:
- Close your DAW completely. Serum can’t have the files open while you move them.
- Copy the entire
Serum 2 Presetsfolder to the new location, for exampleD:Serum 2 Presets. Copy, don’t cut – you want a fallback. - Rename the original folder to
Serum 2 Presets_OLD. - Open Serum 2. Since it can’t find the library, it asks you to locate the folder. Point it at the new drive.
- Load a few patches that use samples or noises to confirm nothing broke.
- After a week of normal use, delete the _OLD folder.
That’s it. Your DAW projects don’t care where the Serum 2 preset folder lives, because patches are saved inside the project file itself – only the browser reads from the library.
One caveat for external drives: the drive has to be mounted before you open a project. And on Windows, a USB drive that changes letters from E: to F: will break the path. Assign it a fixed letter in Disk Management if you go this route.
Backing Up Before an OS Reinstall
Here’s the mistake I made in 2023, on Serum 1: I backed up Presets/User and nothing else. After the reinstall, half my patches loaded with missing noises, because noise files live in their own folder and aren’t baked into the preset.
Serum 2 raises the stakes. Patches built on the Sample, Multisample, or Granular engines reference audio files. Back up only the preset files and those patches come back silent or broken.
So the rule is one line long: back up the whole Serum 2 Presets folder, top level down. Zip it, park it on a cloud drive or external disk, done. My current library zips to about 4 GB – small enough for any cloud plan, big enough that you don’t want to rebuild it from scratch.
Also grab Serum.cfg if you’ve tweaked settings like UseOpenGL=0, and keep your Xfer Records login handy. Serum 2 was a free upgrade for Serum 1 owners, and you’ll re-download the installer from your account. If anything goes sideways, Xfer’s support page covers reinstall and authorization questions.
Why Presets Disappear After Updates
This one causes real panic, so let me say it upfront: your files are almost never gone. When people write in saying an update deleted their presets, the folder on disk is fine every single time.
What actually happens is one of three things.
The browser database needs a rescan
Serum 2’s browser reads from a scanned index, not live from disk. After an update, or after you add files while the plugin is open, that index can lag behind. Go to the Menu tab and rescan the folders on disk. This fixes the majority of missing-preset reports we get.
The custom path got reset
Occasionally an update or a fresh plugin install falls back to the default location. If you moved your library to another drive and suddenly see only factory content, Serum is just looking at the wrong folder. Re-point it to your custom location and everything returns.
The files went into the wrong subfolder
Wavetables in Presets, presets in Tables – the browser filters by content type, so misfiled content is invisible even though it’s sitting right there. This bites people migrating old Serum 1 folders by hand. The good news: Serum 1 presets are compatible with Serum 2, so once they’re in Presets/User, they just work.
By the way, if you’re rebuilding your library after a cleanup, that’s a good moment to restock. Our free pack with 250+ Serum 2 presets ships as a proper pack with its own subfolder, so it lands cleanly in User – and it covers bass, leads, keys, plucks, atmospheres and 808s. There’s also a bigger roundup of free Serum 2 preset sources if you want to go wider, and a separate list of our favorite bass patches if low end is your thing.
FAQ: Serum 2 Preset Folder Questions
Where is the Serum 2 preset folder on Mac?
It’s at ~/Library/Audio/Presets/Xfer Records/Serum 2 Presets. That’s your user Library, not the system one at the root of the drive. Since Finder hides it, press Cmd+Shift+G and paste the path.
Can I use my Serum 1 presets in Serum 2?
Yes. Serum 1 presets load in Serum 2 without conversion. Copy them into Presets/User inside the Serum 2 library, rescan, and they show up. Your old custom wavetables move over the same way, into Tables/User.
Why can’t Serum 2 see presets I just added?
Almost always a rescan issue. Serum indexes the folder rather than reading it live, so trigger a rescan from the Menu tab. If that fails, check the files actually sit inside Presets/User – and on Windows, check whether OneDrive redirected your Documents folder.
Can I keep my library on an external drive?
Yes, and for big sample-heavy libraries I’d recommend it. Just make sure the drive is connected before loading projects, and give it a fixed drive letter on Windows. If Serum can’t find the library, it prompts you to locate the folder again.
That’s the whole map. One parent folder, a handful of subfolders, and a rescan button that solves most emergencies.
If you want something worth putting in that folder, grab our free 250+ Serum 2 presets – no strings attached. Install the pack, open a few patches, and tear them apart to see how they’re built.
I run Monosounds.studio and make the packs myself. Ten-plus years of producing, 97+ releases, 16,000+ downloads. Every Serum 2 preset we ship passes a CPU check on a mid-range laptop and gets used in a real track before release. If it does not survive a mix, it does not go in the pack.
