Owners of Xiaomi Redmi Note 9 Pro smartphones often face the need to quickly find a specific audio file among hundreds of other documents in the device’s memory. The standard interface of the voice recorder application is convenient for recording, but when you want to transfer a file through a messenger or save to a computer, users are lost in the complex file system of the MIUI shell. Understanding the exact structure of folders allows not only to quickly find the desired tracks, but also effectively manage the free space of internal memory.
Modern versions of Android, which are based on the firmware of your smartphone, use strict security policies that change the standard paths to access media files. If previously all audio was in one common folder, now the system can divide records by application or hide them in system directories. In this article, we will discuss in detail where the default voice recorder files are located depending on the version of MIUI, how to change the save path and what to do if the records are lost after the system update.
The Standard Way to Files in Internal Memory
By default, all audio recordings created by a regular application are stored in the internal storage of the smartphone, which provides quick access to files and instant recording without the delays typical of external memory cards. → MIUI → sound_recorder. That's where the name folder lies. call_rec to record conversations or just files with dates for a recorder.
However, the structure may vary slightly depending on which version of the Android operating system and MIUI shell is installed on your Redmi Note 9 Pro. In some cases, the system creates a separate Recorder directory at the root of internal memory, especially if the user has previously changed the save settings.
To quickly navigate to the desired partition, it is recommended to use a built-in Explorer. Open Explorer application, select Phone category and sequentially go to folders. If you do not see the MIUI folder, check the settings for displaying hidden files, although this is rarely required. Files usually have an extension.m4a or.mp3, which ensures their compatibility with most media players.
⚠️ Note: Do not delete or rename the system folder itself sound_recorder or Recorder, as the voice recorder application may stop saving new records correctly or stop running altogether.
Search for records through the built-in Explorer and menu
The easiest way to find a record without knowing the hard ways is to use the functionality of the voice recorder application itself or a smart conductor. The voice recorder app on Xiaomi has a convenient file management menu that allows you not only to listen to, but also to move tracks. Click on the three dots in the upper right corner or the name of the current record to see the item Properties or Show in the folder.
This feature will instantly take you to the system explorer exactly where the file is physically located. This is especially useful if you have previously changed default settings or use third-party launchers. In addition, the built-in file search in MIUI can index audio, so entering a title or part of a conversational phrase (if recognition is enabled) can give a result faster than manual search.
If file-finding is not possible with standard means, you can use third-party file managers such as Total Commander or FX File Explorer. These applications provide more flexible tools for sorting by date of creation, size or file type. In the search bar of such managers, you just need to enter the.m4a extension or part of the file name to filter out excess memory content.

Configuring the conservation path to SD-map
Redmi Note 9 Pro owners often use microSD cards to expand memory, as audio files, especially in high quality, can take up a significant amount. Transferring the save folder to an external card helps free up precious internal space of the system.
In the menu that opens, look for Memory or Saving Path. If the memory card is installed and correctly defined by the system, you will be asked to choose between Internal Memory and SD-Once you choose a new path, all subsequent records will automatically be saved to an external drive. Note that existing files will not automatically move, but you will need to copy them manually.
The memory card has its own peculiarities: the recording speed can be lower than that of the built-in drive, which theoretically can lead to micro-breaks when writing in a very high bitrate. However, for standard settings of the Xiaomi voice recorder, this is not a problem.

Use a Class 10 UHS-I memory card to record audio to avoid artifacts and interruptions during long sessions.
Table: Folder structure and file types
Understanding the file structure will help you navigate the contents of folders faster when you connect your smartphone to your computer. Below is a table describing the main directories and data types you may encounter.
| Location. | Type of contents | File format | Note |
|---|---|---|---|
| MIUI/sound_recorder | Standard recordings of the recorder | .m4a, .mp3 | The default main folder |
| MIUI/sound_recorder/call_rec | Telephone records | .m4a | Requires inclusion in call settings |
| Recorder (root) | Recordings in older versions of MIUI | .mp3 | It is rarely found on new firmware. |
| SD Card/Recorder | Records when selecting external memory | .m4a | If the settings are selected SD-map |
It is important to note that the.m4a format is a modern standard for audio compression that provides good quality with a smaller file size compared to WAV. However, if you want compatibility with older devices, you can force MP3 format to be set in the voice recorder settings. This will slightly increase the size of files, but ensures they open on any device.
When connecting a smartphone to a PC through USB-Cable make sure that the file transfer mode is selected (MTP), It's not just charging, otherwise the computer won't see the internal structure of the folders. MIUI empty when viewing from a computer, try to restart the smartphone without removing the cable so that the system re-mounts the file system.
Recovery of deleted recordings of the recorder
It is not uncommon to have an important record accidentally deleted. Fortunately, there are several levels of data protection on the Xiaomi Redmi Note 9 Pro. The first place to look is in the Recycle Bin in the recorder app itself or in the Files system app. Deleted files are often stored there for 30 days before final erasure.
If you don't have a file in the recycle bin, you can try using specialized data recovery software like Dr.Fone or DiskDigger, which depends on how much memory was overwritten by new data after deleting it, and the fewer write operations you did on your smartphone after losing the file, the better the chances of successful recovery.
⚠️ Note: When using data recovery software on a PC, never save recovered files back to the same memory sector from which they were deleted – this can lead to irreversible damage to the file structure.
Why aren't the files restored?
It's also worth checking out cloud services if you had sync enabled. Xiaomi Cloud or Google Drive could automatically back up audio files. Go to your account settings and check the sections associated with the voice recorder or shared data backup.
Access problems and hidden files
Sometimes users find that the folder with the records is empty or the files are not displayed, even though the recorder claims that the recording was conducted.This may be due to the access rights of applications in Android 11 and higher.
To solve this problem, go to Settings → Applications → All Apps → Recorder → Rights. Make sure you allow access to Memory or Files and Media. Without this permission, the application may simply not see the directory it is trying to write to, or the explorer will not be able to display the contents of the application folder.
Another reason could be a media scanner malfunction, and if you've copied files manually but they don't appear on the playlist, try restarting the device, which will cause the system to scan the memory again and update the media database, and in rare cases, cleaning the Media Storage app's cache through the developer menu helps.
