Users of brand smartphones Xiaomi often face the need to extract audio files of conversations from the internal memory of the device. This may be necessary to archive important information, transfer evidence, or simply to free up space. However, the standard shell MIUI or HyperOS does not always make the path to this data obvious to the average user.
Unlike some other manufacturers, the system Android on devices Redmi has a specific directory structure that has changed with the release of new versions of the operating system. You can find the file you need either through built-in tools or using third-party navigation tools. Understanding the logic of data storage will help you quickly localize the desired track.
In this article we will analyze in detail the physical paths on the disk, the features of the standard voice recorder and the nuances associated with access rights in modern versions of Android. You will learn how to avoid data loss when resetting settings and where exactly the system hides confidential audio recordings by default.
Standard storage paths in the file system
By default, the built-in Phone application saves all recordings to a protected directory of the system. In older versions of the shell MIUI this path was quite simple and understandable. Typically, the files were located in the root of the internal memory or in a folder MIUI. However, with the tightening of Google's security policies, the structure has changed.
Now the main path where the files are physically located looks like this: Internal memory/MIUI/sound_recorder/call_rec. This is where the system creates separate subfolders for each contact or phone number if appropriate sorting is enabled. Inside these directories, files are stored in the format .m4a or .mp3, depending on the codec settings.
It is worth noting that direct access to this folder may be limited in new versions of Android (starting from 11 and above) due to the mechanism Scoped Storage. This means that some third-party file managers may not display the contents of this directory without special permissions. A standard explorer Files usually copes with this task without problems.
⚠️ Attention: When you connect your smartphone to a computer via a USB cable in file transfer mode (MTP), the folder call_rec may be hidden or displayed as empty. This is a system security mechanism that prevents unauthorized access to personal conversations.
MIUI and HyperOS shell interfaces are regularly updated by developers. The location of system folders may change slightly in new firmware. We recommend checking the current paths in the official documentation or settings of a specific voice recorder application.
Search through the built-in explorer and the Voice Recorder application
The most reliable way to find a recording without knowing the exact path is to use the functionality of the recording application itself. In smartphones Redmi the voice recorder and phone book functions are closely integrated. By opening the application Dictaphone, you will see a list of all recordings, sorted by date.
To go to a file in the storage, just click on a specific entry and select the “More details” option or the information icon (usually a letter i in a circle). In the menu that opens, there is often an item “Show in folder” or similar, which will automatically take you to the desired directory through the system explorer. This eliminates the need to manually wander through directories.
If you prefer to search for files manually through the app Explorer, use the function of sorting by file type. Select the Audio or Music category. The system will scan the internal memory and display all audio tracks. Call recordings usually have the date and time of the call in the name, which makes them easier to identify among music tracks.
Use the search by file extension in Explorer. Enter ".m4a" or ".mp3" in the search bar to filter out unnecessary files and quickly find the desired conversation recording.
- 📂 Open the application Explorer on your desktop.
- 🔍 Click on the magnifying glass icon and enter the contact name or phone number.
- 📁 Go to the section
Internal storage→MIUI. - 🎵 Open the folder

Features of storage in Xiaomi cloud services
Many users forget that their data can be duplicated in the cloud. The ecosystem Xiaomi offers a service Xiaomi Cloudthat, with active synchronization, can save copies of conversation recordings on remote servers. This is a convenient way to restore information if your device is lost or damaged.
To check the availability of records in the cloud, you need to go to your account settings Mi Account. In the “Cloud” section, find the “Voice Recorder” or “Call Recordings” item. If the switch is active, your files are uploaded to the Internet. They can be accessed via the web interface i.mi.com from any computer or other smartphone.
It is important to understand the difference between local and cloud storage. Deleting a file from your phone while synchronization is enabled may lead to its deletion from the cloud (depending on the trash settings). Therefore, before clearing the memory, make sure that important files are saved in another location or disable synchronization for this folder.
Free cloud limits
The free plan of Xiaomi Cloud provides only 5 GB of space. High-quality call recordings take up a lot of space, so the cloud can fill up quickly. It is recommended to periodically upload archives to a computer.
Access to recordings via a computer (ADB and MTP)
For advanced users who need to bulk copy an archive of conversations, connecting to a PC is the optimal solution. However, as mentioned earlier, the MTP (Media Transfer Protocol) mode can hide system folders. In this case, USB debugging comes to the rescue.
Using the tool Android Debug Bridge (ADB) gives full access to the file system, bypassing interface restrictions. You will need to enable USB Debugging in the Developer Options menu. After connecting to your computer, you can run a command to copy the entire folder with recordings.
adb pull /sdcard/MIUI/sound_recorder/call_rec/ C:/Backup_Calls/
This command will copy the entire contents of the calls directory to a folder Backup_Calls on drive C of your computer. The method works faster and more reliably than manual copying through Windows Explorer, especially if there are hundreds of files. It also bypasses the problem of “invisible” folders with a normal cable connection.
Using ADB is the only guaranteed way to access all recording files if the standard Explorer on a PC does not display hidden Android system directories.
Table of paths and file formats
For clarity, here is a summary table that will help navigate the variety of paths and formats used in different firmware versions. Please note that the file extension affects the ability to play it on older devices.
| MIUI / Android version | Folder path | File format | Access via MTP |
|---|---|---|---|
| MIUI 10-12 (Android 9-10) | /MIUI/sound_recorder/call_rec | .mp3 / .m4a | Full access |
| MIUI 13-14 (Android 11-12) | /MIUI/sound_recorder/call_rec | .m4a | Limited access |
| HyperOS (Android 13+) | /Android/data/com.android.incallui/... | .m4a (AAC) | Hidden (need Root/ADB) |
| Third-party applications | /Recordings/CallRecorder | .wav / .mp3 | Full access |
As can be seen from the table, with the transition to HyperOS the paths became more confusing due to Google's security requirements. The format .m4a has become a de facto standard due to better compression while maintaining voice quality, however, it may not open on very old players without installing additional codecs.
Solving problems with missing recordings
There are situations when the recording function is enabled, but the files do not physically appear in the folder. Most often, the problem lies in the access rights of the Phone application. In your smartphone settings, go to the “Applications” section → “All applications” → find “Phone” (or “Services and feedback”)
Check the “Permissions” section. Make sure the app has access to Memory or Files and Media. Without this permission, the system simply cannot save the created audio file to disk, and it is lost immediately after the call ends. It is also worth checking the availability of free space in the internal storage.
Another reason may be the use of third-party applications for calls, such as Google Phone, which is pre-installed on global versions of smartphones. In some regions, the recording function in it is disabled by law or software. In this case, records are not created at all, and there is no point in searching for them in folders.
⚠️ Attention: If you used a third-party application to record calls, and not the standard one, the path to the files will be completely different. Usually this is a folderCallRecorderin the root of the internal memory or in a directoryAndroid/media.
☑️ Diagnosis of missing entries
Frequently asked questions (FAQ)
Is it possible to change the folder for saving recordings on an SD memory card?
In the standard “Phone” application from Xiaomi, this option is usually not provided. The system forcibly writes files to internal memory to ensure stability and writing speed. However, some third-party call recording applications allow you to select a memory card in their settings.
Why do call recordings disappear after a system update?
During global firmware updates, application settings are sometimes reset or the file system structure is changed. If the path to the folder has changed, old files may remain in the old directory, and new ones may be written to the new one. Accidental deletion is also possible when clearing the cache if the user has selected incorrect reset options.
How to listen to a recording on a computer if it does not open?
Format files .m4a are standard and should be opened by any modern player (VLC, Windows Media Player). If the file does not play, it may be damaged or encrypted (which is rare for a stock voice recorder). Try renaming the extension to .mp3 or use a universal player VLC.
How much space does one hour of conversation recording take?
The file size depends on the selected recording quality and codec. On average, one hour of conversation in AAC (.m4a) format takes from 30 to 60 MB. When using the format WAV (high quality without compression), the volume can reach 600 MB or more in the same period of time.
