Owners of Xiaomi, Redmi and POCO smartphones often face a situation when it is urgent to find a stored audio recording of an important conversation. The standard call interface is not always convenient for navigating through the archive, especially if there are hundreds of records. Understanding the structure of the Android file system in the shell of MIUI or HyperOS becomes a critical skill.
In this article, weβll take a closer look at where audio files are physically stored, how paths vary depending on the operating system version, and what tools will help manage that content. Starting with Android 11, Google has implemented strict restrictions on access to system folders, which has changed the standard way to search for records on all modern smartphones.
We will look at both standard viewers and advanced methods of working with files via a computer, and will also touch on the issues of audio encoding formats, since the old models use one codec and the new ones use a completely different one, which affects playback on third-party devices.
The most obvious and affordable way to find the right file is to use the built-in File Manager application. MIUI The folder structure was more open and understandable to the average user, usually going straight to the root of the internal memory where the folder was. MIUI, and inside β sound_recorder. However, with the release of new versions of Android (11, 12, 13 And above, the security system stopped letting the user directly into some system directories without special permissions, and now, when you open the Internal Shared Drive, you may not see the usual folders right away. You'll need to go to the Android section, then the data, and search for the batch names of the applications. For a regular voice recorder and call recorder, the paths may differ depending on which application was used to record the applications. If you used a standard call, look for files along the way: π /MIUI/sound_recorder/call_rec/ β Classical Way for Older Versions MIUI. π /Android/data/com.android.soundrecorder/files/Recordings/Call_rec/ β current path for new versions of the system. π /MIUI/sound_recorder/ β It often stores shared records of the recorder unless they are separated. β οΈ Warning: When you try to open a data folder inside the Android directory on new smartphones, the system may issue a security alert or simply show an empty folder. To access hidden content, some file managers will require special permission or switch to Documents mode. If the standard Xiaomi Explorer does not show files, try the third-party solutions discussed below. It is important to understand that files can have extensions.m4a or.mp3 depending on the recording quality settings. π What is your Xiaomi smartphone?:Redmi Note (any series)Xiaomi Mi / Digital seriesPOCO (F, X, M Series Black Shark
Search for records via computer (USB Mode)
Connecting your smartphone to your computer via USB-cable is one of the most reliable methods of navigating the file system. When you connect the device to the PC, select the mode of file transfer in the notifications on the phone screen (MTP). This will allow the computer to see the internal memory as a normal hard drive.
On your computer, open "My Computer," find your device, and go to the internal storage, and you can see the folder structure more clearly, and many of the hidden limitations of the mobile interface are removed. MIUI. If it's not at the root, look in the Android folder. Inside you're interested in the directory. sound_recorder.
Often users confuse folders because the system can create duplicates or hide content. Make sure you look at internal memory instead of internal memory. SD-The path to recording conversations on a PC often looks like this:
This computer > Xiaomi > Internal shared storage > MIUI > sound_recorder > call_recIf you can't see the folder MIUI root, check the folder. Android/data/com.android.soundrecorder/files/Recordings/Call_rec. Files here are usually sorted by date of creation. For ease of search on the computer, you can turn on the display of hidden files, although call records are usually visible by default.

Use the Change Date Sort feature in Windows Explorer or macOS to quickly find the most recent records without going through hundreds of files manually.
Use of Third-Party File Managers
Xiaomiβs regular Explorer is functional, but sometimes limited in access to system partitions of new versions of Android. Installing a specialized file manager from Google Play can solve the problem of βempty folders.β Popular applications such as Total Commander, FX File ExplorerFiles by Google, are able to correctly request the necessary permissions.
When you first run an app on Android 11+, it will ask for access to the Android/data folder. You need to click "OK" or "Allow", then the system folder selection window will open, search in the data list and confirm the selection at the bottom of the screen ("Use this folder").
After obtaining the rights, you will be able to freely move through the structure:
- π Total Commander: Allows you to copy files directly to cloud drives or transfer over Wi-Fi.
- π FX File Explorer: Has convenient network access and a powerful search engine for the content of files.
- π CX File Explorer: Excellent memory analysis and memory graphs, helping to find heavy audio files.
These applications often have an audio player built in, allowing you to listen to the recording directly in the manager interface without opening a separate application, which greatly speeds up the process of finding the right conversation among many similar files.

Differences in formats and codecs of recording
File structure is only half the story. The second important aspect is the audio storage format. Xiaomi smartphones can use different codecs depending on the model and version of MIUI. Older devices often wrote sound in.mp3 or.amr format, which ensured maximum compatibility.
Modern models, especially those running Android 12/13/14, have switched to.m4a (AAC codec) format, which provides better sound quality with a smaller file size, but may not play on older voice recorders, tape recorders or some video players without installing additional codecs.
Below is a table of the correspondence of models and likely recording formats:
| MIUI / Android version | Typical format | Sound quality | Compatibility |
|---|---|---|---|
| MIUI 10-11 (Android 9) | .mp3 /.amr | Average. | Tall (all players) |
| MIUI 12-13 (Android 10-11) | .m4a | High. | Medium (needs codec) |
| HyperOS / MIUI 14 | .m4a /.aac | Very high. | Low (requires conversion) |
If you find files with an extension that your player doesn't understand, don't rush to delete them. Just rename the extension to.mp4 (sometimes helps) or use a converter. However, most often the problem is solved by installing a universal player, such as VLC for Android, which is "omnivorous" and reads any formats.
Access problems on Android 11, 12, 13 and later
Since Android 11, Google has implemented a Scoped Storage policy, which means that apps (and the user) are not allowed to read the contents of the /Android/data/ folder directly without explicit, verifiable permission, which is why many users complain that the records are βmissingβ or βthe folder is empty.β
The files are actually still there. They're right there. /Android/data/com.android.soundrecorder/files/Recordings/Call_rec/. But a standard conductor can show this folder to be empty. To see files, you either need to use a computer (mode). MTP), or a special file manager that can request access through the system API.
β οΈ Warning: Do not attempt to manually rename or move the com.android.soundrecorder system folder.This may cause the Calls app to stop seeing a path to save new records and the autowrite function will stop working.
Another feature of new versions of HyperOS is the separation of access rights, and sometimes the call recording may not be stored in the shared voice recorder folder, but in the phone application folder.
/Android/data/com.android.dialer/files/CallRecordings/Here, com.android.dialer is the batch name of a standard caller. The path can vary depending on the regional firmware (Global, China, Russia).
What if the Android/data folder doesnβt open at all?
How to change the way of saving and setting
Many users would like to change the default save path, such as migrating records immediately to the default save path. SD-It's a card to keep the internal memory from clogging. MIUI HyperOS is often missing or hidden, and the system tends to store media in internal storage for performance.
However, it's worth checking the settings. Open the Recorder app (which is often combined with call recording). Click on three dots in the corner or the menu button, then select Settings. Here you can find Record Quality or Save Folder.
If you don't have the option to change the folder, you can use a trick: create a shortcut or use the sync function. However, the most reliable way is to regularly manually or automatically clean the folder. sound_recorder cloud storage (Google Drive, Yandex.Disk, Mi Cloud) if this option is supported in your region.
π‘
Changing the system way to save call records without root rights on new versions of Android is almost impossible due to Google's security limitations.
Recovering Deleted Records of Conversations
It's a common situation where an important record has been accidentally deleted. If you cleared a file from a folder but didn't clear the bin, the chances of recovery are high. Xiaomi's file manager has a built-in Recycle Bin. It usually stores deleted files for up to 30 days.
To check the Recycle Bin, open Explorer, go to Documents category or click on the menu (three bars), and select Recycle Bin. If there is a file there, just highlight it and click Restore.
If the file is deleted and from the basket, the situation is more complicated: the data does not disappear instantly, only the space is marked as free to write. Until you write new heavy files (video, games) on top, there is a chance. Use specialized software for PCs, such as Dr.Fone, DiskDigger (there is an Android version) or Recuva (for memory cards).
- πΎ DiskDigger: Can find file residues even without root rights, but in a limited mode.
- πΎ Recuva: It works great if you connect your phone as a drive (MTP) pull out SD-map.
- πΎ Mi Cloud: Check Xiaomi's cloud. If voice recorder sync was enabled, the copy could fly to the cloud automatically.
β οΈ Warning: When you try to recover data, stop using your phone immediately. Don't take new photos, download movies, or install apps. Any new recording to disk reduces your chances of success.
Remember that recording of conversations is governed by the laws of your country, and make sure that the use of recorded files does not violate the rights of the interlocutor and privacy laws.
