How to clean the folder “Other” on Xiaomi Redmi 7A: step-by-step instructions with pictures

The “Other” folder on Xiaomi Redmi 7A is one of the most mysterious to users, it can take anywhere from a few hundred megabytes to a few gigabytes, but it doesn’t show up in the standard file manager. Many people mistakenly think it’s system junk that can be simply removed — but it’s actually more complicated.

In this article, we'll look at what the Other category is, why it's growing, and how to clean it up without risking damage to the operating system. We've tested all the ways in Redmi 7A with MIUI 10-12 firmware, and we've only identified the methods that work, from manual cleaning to using hidden MIUI features.

Important: Some files in the Other folder are critical to the smartphone, and deleting them can cause app malfunctions or even a device blink (completely inoperable).

What is the “Other” folder on Xiaomi Redmi 7A and why does it take up so much space?

In MIUI, the Other folder is a collective name for files that the system cannot categorize as standard (photos, videos, audio, documents).

• 📁 Application cache (including hidden cache of system services)
• 🔄 Temporary files from updates MIUI applications
• 📱 Logs of the system (logcat, error dumps)
• 🔒 Encrypted data (e.g. from Mi Account or Google Services)
• 🗑️ Remnants of Remote Applications (Incomplete Uninstallation)
• 🛠️ Recovery files (if previously resetted)

On Redmi 7A with 16/32GB of memory, the Other folder often grows because of:

1. Automatically create memory dumps when crashes (especially if the phone often overheats or turns off due to low charge).
2. Misfunction of the MIUI file manager, which does not clear the cache after updates.
3. Use third-party launchers (such as Nova Launcher or POCO Launcher) that leave their temporary files.

According to our testing, on Redmi 7A with MIUI 12, the “Other” folder takes an average of 1.5 to 4.5 GB – and this is despite the fact that there are no more than 300-500 MB of really useful data.

Method 1: Cleaning through the built-in MIUI Optimizer

The safest method is to use the standard MIUI tool, which does not delete critical files, but helps to get rid of unnecessary cache and temporary data.

Instructions:

1. Open the settings → About the phone → Memory.
2. Slip on the “Other” section (may be called “Other Files”).
3. Click on “Clean” or “File Management”.
4. Select the categories to delete (we recommend to note "Cash", "Temporary files", "Logins").
5. Confirm the action.

⚠️ Note: If the memory is not free after cleaning, then the files are locked by the system.

Method 2: Manual deletion via file manager (for power users)

Some files from the Other folder can be manually deleted, but this requires granting superuser rights (root) or using ADB. Without root rights, you can only clean non-system files.

Instructions for users without root:

1. Install a file manager with access to hidden folders, such as FX File Explorer or Solid Explorer.
2. Enable the display of hidden files in the manager settings.
3. Go to folders: /storage/emulated/0/Android/data/ – application cache /storage/emulated/0/MIUI/ – MIUI logs and dumps /storage/emulated/0/Download/.thumbnails – thumbnails
4. Delete files with extensions:.log,.tmp,.bak,.old.

⚠️ Note: Do not delete files in folders /system, /data/data or with extensions.db,.odex - this can cause a system failure.

Method 3: Cleaning through Safe Mode

If the Other folder has grown because of viruses or app malfunctions, Safe Mode will help, only system services are loaded, and third-party applications are disabled.

How to start:

1. Press the power button before the off menu appears.
2. Press and hold the “Switch off” option (or “Reboot” depending on the MIUI version).
3. Confirm the transition to Safe Mode.
4. In Safe Mode, check the memory through Settings → Memory and clear “Other”.
5. Restart your phone in normal mode.

If the memory is back full after you exit Safe Mode, the problem is in one of the installed applications. Find it through Settings → Applications → Latest and delete.

Method 4: Resetting cache via Recovery Mode

It's a radical but effective method that cleans all temporary system files, including update cache and error dumps, if previous methods didn't work.

Instructions:

1. Turn off the phone.
2. Press the power button + volume button at the same time before the MI logo appears.
3. In the Recovery menu, select the language (if you have a choice).
4. Go to Wipe & Reset → Wipe Cache.
5. Confirm the action and wait for the completion.
6. Reboot your phone (Reboot → System)

⚠️ Note: Do not confuse Wipe Cache with Wipe Data – the latter erases all user data (photos, contacts, applications)!

💡

If the phone is running faster after the cache is reset, but the memory is filling again, install the SD Maid app (requires root) for automatic cleaning.

Method 5: Using ADB for deep cleaning (for advanced)

If you are familiar with ADB (Android Debug Bridge), you can delete hidden files without root rights.

Instructions:

1. Install ADB on PC (instructions are available on XDA Developers).
2. Connect Redmi 7A to USB and enable debugging over USB (Settings → About Phone → MIUI version – tap 7 times, then go back to Additional → For Developers).
3. In the command line, type: adb devices (you should see your device).
4. Follow the instructions for cleaning: adb shell pm clear com.miui.cleanmaster – cleaning the cache of the adb shell optimizer rm -rf /data/local/tmp/* – deleting temporary files adb shell rm -rf /cache/* – cleaning the cache of the system

Once you have completed the commands, restart your phone, which removes up to 1-2 GB of unnecessary files, but requires caution.

💡

If you're not sure what type of file you want, you better not delete it. Most of the critical data is stored in /system and /data/data folders, which you can't access without root.

Frequent Mistakes and How to Avoid Them

Many Redmi 7A users make the same mistakes when cleaning the Other folder.

• 🚫 Delete files to blind – for example, erase all contents of the folder /MIUI It may cause a breakdown of the design.
• 🔄 Ignoring backup – before any manipulation of system files, make a backup through Settings → Additionally. → Backup.
• 🔧 Using Play Market cleaners – most of these apps (like Clean Master) not only don’t help, but also create additional garbage.
• 📉 Frequent resets of cache via Recovery – this can cause the phone to slow down due to constant Dalvik-cache reassembly.

If the memory is quickly filled again after cleaning, check:

1. Are there pirated apps on the phone (they often create hidden files)?
2. Is not automatic log recording enabled in the settings for developers?
3. Is the phone used as a Wi-Fi hotspot (this creates a lot of temporary files)?
