Unpacking the cache of games on Xiaomi is a task faced by many gamers who want to transfer heavy projects such as Genshin Impact, Call of Duty Mobile or the Internet. PUBG It's not rebooted on another device, unlike standard ones. APK-Files, cache (usually in.obb or.zip format) store graphic resources, levels and other data that take up gigabytes of memory. POCO This process is complicated by the features of the file system. MIUI, where access to system folders is limited even without root rights.

In this article, we will discuss 5 working methods of cache extraction - from simple (using built-in tools) to advanced (via built-in tools) ADB We will focus on the nuances for different versions. MIUI (12-15) and models, including Black Shark gaming smartphones, and you’ll also learn how to avoid “Failed to extract” errors or data loss when transferring.

Warning: Some methods require debugging USB If you're a beginner, start with the first two methods. ADB or TWRP.

1.Where the cache of games on Xiaomi is stored: paths to folders

Before you extract the cache, you need to know where it is. MIUI The paths to game data depend on the Android version and the type of game:

• 📁 Normal games (APK + OBB): folder /Android/obb/[package_name] (for example, /Android/obb/com.activision.callofduty.shooter for COD Mobile).
• 🎮 Internal Cache Games (Genshin Impact: Folder) /Android/data/[package_name]/files or /Android/data/[package_name]/cache.
• 🔒 System Games (Pre-installed): Can be stored in /data/app/[package_name] — root-only.

On Xiaomi MIUI 14/15 These folders are hidden by default, so you can see them:

1. Open any file manager (e.g., Mi File Explorer or Solid Explorer).
2. Enable the display of hidden files: Three dots → Settings → Show hidden files.
3. Go to the root directory (/storage/emulated/0/).

💡

If the Android folder doesn’t show up even after you enable hidden files, try using a file manager from a third-party developer (e.g., a file manager from a third-party developer, FX File Explorer or connect your smartphone to your PC via USB file transfer (MTP).

Not all games store cache in.obb format. For example, Honkai: Star Rail uses encrypted files in a folder. /data, You can't get them out without rooting. Check the requirements of a particular game on the developer's website.

2. Method 1: Extract cache through the built-in file manager

The easiest way is to copy the cache files directly through Mi File Explorer, which works for most games if the cache is stored in the same file. /Android/obb or /Android/data.

Step-by-step:

1. Open Mi File Explorer (Folder icon on the desktop).
2. Move to the /storage/emulated/0/Android/obb/ (or /Android/data/).
3. Find a folder with the name of the game package (for example, com.miHoYo.GenshinImpact).
4. Hold your finger on the cache file (usually.obb or.zip), then click Copy.
5. Insert the file into a convenient folder (for example, Downloads) or on SD-map.

If the file is not copied, check:

• ⚠️ Is there enough space on the target medium (Genshin Impact cache weighs) ~15GB!).
• ⚠️ Is access to the folder blocked (on some firmware) MIUI Reading permission required).

On Black Shark smartphones, the path to cache may be different: instead of /Android/obb/ Look for the file. /BlackShark/obb/ or /BSGameSpace/.

Method 2: Transferring cache over PC (USB + MTP)

If the file manager on your smartphone is not working, connect Xiaomi to your computer, a method that is more reliable because it avoids copying errors on large files (>4GB).

3. On PC, open this computer. → Find the Xiaomi device in the Devices and Disk section.
4. Go to the internal drive. → Android → obb (or data).
5. Copy the necessary files to the hard disk of the PC.

⚠️ Note: When copying large files (>10 GB through MTP There's a possibility of errors. If the process is interrupted, try it:

• Uncash the cache directly on your smartphone (if it is.zip).
• Use alternative protocols, for example, FTP-server FX File Explorer and Solid Explorer can do this).

Method 3: Use ADB for extracting cache (without root)

If the su command doesn’t work, your Xiaomi doesn’t have root, so try an alternative route:

adb pull /sdcard/Android/obb/[package_name] C:\cache_backup

💡

ADB It allows you to extract cache even from secure folders, but not all games store data in accessible locations. For example, Diablo Immortal encrypts the cache, and it can only be transferred through the official launcher.

⚠️ Attention: Some firmware MIUI block access /data even ADB. In this case, only unlocking the loader and installing a custom Recovery will help (TWRP).
