If you're trying to free up space or fix a stubborn client issue, knowing how to uninstall Zenless Zone Zero the right way matters more than you might think. In 2026, with ZZZ Version 2.7 "Champions Never Fall to the Past" pushing the PC install size well past 40 GB once voice packs are included, a sloppy uninstall can leave a surprising amount of junk behind. Whether you're taking a break from New Eridu, moving to another platform, or just dealing with a launcher problem, the good news is simple: uninstalling the game does not erase your account progress, Signal Search pity, or Polychrome, since all of that lives on HoYoverse's servers.

How to Uninstall Zenless Zone Zero Fast

Before we get into the platform-by-platform steps, here's the quickest way to remove ZZZ depending on where you play. No matter which option you use, your account data stays safe because Proxy progress is stored server-side, not on your device.

Platform Fastest Method Approximate Storage Freed Account Data Safe?
PC (Windows) HoYoPlay launcher uninstall 40–60 GB+ Yes
PC (Mac) Applications folder drag to Trash 40–60 GB+ Yes
Android Settings > Apps > Uninstall 15–25 GB Yes
iOS Long-press > Remove App 15–25 GB Yes
PS5 Home screen > Delete 30–50 GB Yes
Xbox Series X/S Manage Game > Uninstall All 40–60 GB Yes

That means your Inter-Knot level, Agent roster, W-Engines, Drive Discs, faction progress, and event data all remain intact. You can reinstall later, sign back in, and pick up right where you left off.

How to Uninstall Zenless Zone Zero on PC

HoYoPlay Launcher Uninstall

On Windows, the easiest and cleanest first step is uninstalling through the HoYoPlay launcher. Open HoYoPlay, find Zenless Zone Zero in your library, click the gear or settings icon next to it, and choose Uninstall. After that, confirm the prompt and let the launcher remove the main game folder.

Before you do that, though, make sure ZZZ is not still running in the background. A crash, forced close, or half-finished launch can leave processes active, and those can block the uninstall. Open Task Manager with Ctrl + Shift + Esc and end anything labeled ZenlessZoneZero.exe or related HoYoPlay processes before trying again.

Version 2.7 takes up a pretty hefty chunk of storage on PC, especially if you installed extra voice packs. If you also grabbed the pre-download package before the 2026/03/24 maintenance, there may be another roughly 4 GB of update data sitting there too. HoYoPlay usually removes the main install just fine, but it does not always clean out every launcher cache file, so a manual sweep is still worth doing.

Windows Full Cleanup

Once HoYoPlay finishes, it's smart to double-check Windows itself. Head to Settings > Apps > Installed Apps and search for "Zenless Zone Zero." If the game still appears there for any reason, use the Windows Uninstall option to remove whatever registration or leftover uninstall entry remains.

This next part is the one most players skip: leftover folders. If you want a truly clean uninstall and the full SSD space back, check these locations manually and delete any ZZZ-related files you find:

  • C:\Users\[Username]\AppData\Local\miHoYo\ZenlessZoneZero — local settings and cached game data

  • C:\Users\[Username]\AppData\LocalLow\miHoYo\ZenlessZoneZero — shader cache and persistent config files

  • C:\Users\[Username]\AppData\Local\HoYoPlay — HoYoPlay leftovers, including manifests and launcher cache

After that, press Win + R, type %temp%, and clear out temporary files that may have piled up during updates, repairs, or integrity checks. Then empty the Recycle Bin so the storage is actually reclaimed. If you want to be extra thorough, run Disk Cleanup from the Start menu and scan the system drive for any remaining cached update data.

Mac Full Removal

On Mac, the first step is straightforward: open Finder, go to Applications, find Zenless Zone Zero, drag it to the Trash, and empty the Trash. That removes the main app bundle, but not everything tied to it.

To fully clean it out, open Finder and press Command + Shift + G. Enter ~/Library/Caches/ and remove any HoYoverse or ZZZ-related cache folders there. Then use the same Go to Folder shortcut and check ~/Library/Preferences/ for .plist files connected to com.mihoyo or com.hoyoverse. Deleting those clears old preferences and helps avoid weird config issues if you plan to reinstall later. Once that's done, restart your Mac to flush any lingering in-memory references to the removed app.

How to Uninstall Zenless Zone Zero on Mobile and Console

Android and iPhone Uninstall

On Android, the fastest route is usually Settings > Apps > Zenless Zone Zero > Uninstall. You can also uninstall it directly through Google Play, which does the same job. Depending on what resource packs you downloaded, the Android version usually takes up around 15–25 GB, so freeing that space can make a pretty noticeable difference right away.

On iPhone, press and hold the ZZZ icon on your Home Screen, tap Remove App, then choose Delete App. You can also go through Settings > General > iPhone Storage if you want to see exactly how much space the game is using before deleting it.

On both mobile platforms, your account is still safe after uninstalling. When you reinstall, just sign back in with your HoYoverse email and password, or use the linked social login, and your progress comes back normally. The only thing you'll need to do again is re-download the game assets on first launch.

PS5 and Xbox Uninstall

On PS5, highlight Zenless Zone Zero on the home screen, press the Options button, and select Delete. That removes the main game client. If you want to be thorough, also check Settings > Storage > Console Storage > Saved Data for any locally cached session files tied to the game.

There's one extra thing worth checking on PS5: pre-download and reserved update data. Official HoYoverse patch notes listed Version 2.7 pre-download data at roughly 13 GB, and some of that can stick around under Additional Game Content in the Storage menu even after the main app is gone.

On Xbox Series X/S, go to the home screen or My Games & Apps, highlight the game, press the Menu button, then open Manage Game & Add-Ons and choose Uninstall All. That removes the base game along with staged update files. For players who had Version 2.7 preloaded, that can mean recovering around 17 GB of extra space.

Before uninstalling on either console, it is a good idea to confirm your HoYoverse cross-save account is linked properly at account.hoyoverse.com. That way, your UID and account data are ready to access again whenever you reinstall on console, PC, or mobile.

Zenless Zone Zero Leftover Files and Storage Cleanup

Even after a normal uninstall, ZZZ can leave behind more data than you'd expect, especially on PC. HoYoPlay keeps its own cache for downloads and pre-download packages, so if you staged a future patch before uninstalling, those files may still be sitting in the launcher's working folders instead of the main game directory. Voice packs are another common culprit. If you downloaded multiple languages over time, those audio files can quietly eat up several extra gigabytes.

Because of that, it's best to verify your storage recovery instead of just assuming everything is gone. A quick way to do this is to right-click the drive where ZZZ was installed, open Properties, and compare the free space before and after uninstalling. If the number looks off, go back to the old install path and see whether any folders are still there.

A few common leftovers include:

  • Persistent folders used for launcher manifests and integrity data

  • old pre-download files

  • voice pack subfolders

  • staging directories such as BH3_Data or similarly named folders that survived removal

If you're preparing for a clean reinstall, make sure there are no ZZZ-related folders left in C:\Program Files, C:\Users\[Username]\AppData, or whatever custom install directory you used originally. Starting from a truly blank folder setup helps avoid config conflicts and weird launcher behavior later.

Zenless Zone Zero Uninstall Problems and Reinstall

Uninstall Stuck or Failed

If the uninstall freezes, stalls, or just refuses to finish, the most common reason is a background process still locking game files. Open Task Manager and end every related process you can find, especially ZenlessZoneZero.exe, HoYoPlay.exe, and any crashpad_handler entries. In a lot of cases, that alone fixes it.

If it still won't go through, try launching HoYoPlay as an administrator. Right-click the launcher and select Run as Administrator, then retry the uninstall. Sometimes Windows just needs those elevated permissions to release locked files and finish the job properly.

For the more annoying edge cases, like repeated uninstall failures or an endless integrity check loop, booting Windows into Safe Mode can help a lot. You can get there through Settings > System > Recovery > Advanced Startup. Safe Mode disables most third-party services and antivirus hooks, which are often what interfere with game uninstallers in the first place. Some players also run into the infamous Checking Resource Integrity loop where the launcher hangs at 0.00% or 99.99%; in those situations, uninstalling instead of repairing often works once every background process has been shut down.

Reinstall After Uninstall

If you're reinstalling Zenless Zone Zero, stick to official download sources. On PC, that means the HoYoPlay launcher from hoyoplay.hoyoverse.com or the Epic Games Store. On mobile, use Google Play or the iOS App Store. On console, download it again from the PS Store or Microsoft Store. Third-party mirrors and unofficial launchers are simply not worth the account security risk.

After reinstalling, make sure you log into the correct regional server: America, Europe, Asia, or TW/HK/MO. This matters because your UID and saved account data are tied to that server. If you are not sure which one you used before, check your original registration email or test each server until your character data shows up.

Once you're back in, everything linked to your account should return automatically: your Agent roster, W-Engines, Drive Discs, Polychrome, and Signal Search pity included. On PC, it's also smart to do one clean test launch after reinstalling. Boot the system with only essential services running and make sure the game opens normally, especially if you were reinstalling to fix crashes or launcher conflicts.

Conclusion

The best way to handle how to uninstall Zenless Zone Zero really comes down to your platform, but the overall approach stays the same: use the official uninstall option first, then check for leftover cache and launcher files if you want all your storage back. HoYoPlay is the best starting point on PC, while mobile and console players can usually remove the game in a single step through system menus.

Most importantly, your progress is safe. Your Signal Search pity, Polychrome, Agents, and story progress stay on HoYoverse's servers, so you can come back whenever you want. If New Eridu pulls you in again later, just reinstall from an official source, log back into your account, and you're right back in business, Proxy.
