Owners of Xiaomi, Redmi and POCO smartphones often face the need to transfer audio recordings to a computer or save them to the cloud, but the standard voice recorder interface is not always convenient for mass file management. Searching for records through the file manager becomes the only right solution, especially when you need to copy several lectures or interviews at once. Understanding the structure of the MIUI and HyperOS file system allows you to quickly find the right tracks, bypassing long searches in the application menu.
The Android file system on the Chinese manufacturer’s devices has its own specifics, different from the “pure” Android: records are not scattered chaoticly, but strictly structured in system directories, access to which is possible through any conductor. The path to files is usually hidden from the surface of the eye so that the user does not accidentally delete system data, but for the folder with the voice recorder, open access is made. Knowing the exact address of the directory will save you time when connecting your smartphone to your PC through a PC. USB-cable.
In this article, we will discuss in detail where audio files lie, how to change the default save format, and what to do if the folder is empty or hidden. The standard path to records always starts with the internal storage root directory and leads through the MIUI folder. We will also discuss format compatibility and how to automatically upload records to the cloud, which is critical for storing important data when changing devices.
Standard path to voice recorder files in the system
The vast majority of users are looking for an answer to the question where the records are stored, and the answer lies in the standard MIUI directory structure. By default, the Dictophone app stores all the tracks created to the root memory of the device, not to the SD memory card, even if it is installed. This is done by developers to ensure maximum write speed and prevent errors when the memory card crashes.
To find files, you need to open any file manager, like the standard Explorer or the more advanced Total Commander, and you need to go to the Internal Storage section. MIUI, It contains data from most pre-installed applications. sound_rec, Which is short for "sound recording».
- 📂 Open the “Conductor” app on the main screen.
- 📂 Go to the “Internal Drive” or “Device Memory” section».
- 📂 Find and open a folder with the name MIUI.
- 📂 Inside, find the directory. sound_rec — That's the vault.
Inside the folder. sound_rec You will find files with extension.m4a or.mp3, File names are usually generated automatically based on the date and time of the recording, which makes it easier to sort them out unless you've renamed them manually:
| Parameter | Meaning/The Way | Note |
|---|
| Root folder | Internal storage | The main memory of the phone |
| System directory | MIUI | Contains data systems |
| Folder of the record | sound_rec | Recorder audio storage |
| File format | .m4a / .mp3 | Depends on the quality settings |
Before you start copying files, it is worth figuring out what format they are written in, because it depends on their compatibility with other devices. Modern versions of the HyperOS and MIUI 14 shell often use the AAC format (container.m4a), which provides good quality with a smaller file size. However, MP3 is better for maximum compatibility with older players or car radios.
You can change the format of the recording in the settings of the Dictophone app itself. Click on the three dots in the corner of the screen or the gear icon to enter the settings menu. Here you will find the "Record Quality" item, where you can choose between "High", "Normal" or "Traffic Savings." The choice of "High" activates the mode without compression or minimal compression, which is critical for music recordings or silent-voiction lectures.
⚠️ Note: Records take up significantly more space when choosing the best quality. One hour of audio in a non-compression format can weigh more than 500 MB, so keep an eye out for free space in the internal drive.
If you plan to transfer files to Apple devices or use them in professional editing programs, the M4A format may require conversion. Although modern players on Windows 10/11 play it without problems, older systems may not recognize the codec, in which case it is easier to immediately set up the recorder to record in MP3 to avoid unnecessary actions with converters in the future.
Why is M4A better than MP3?
Format M4A (AAC) It provides the best sound quality with the same bitrate as MP3. This is a modern compression standard that uses less processor resources when decoding, which has a positive effect on the autonomy of the smartphone when listening.> Search for hidden and system files Sometimes users are faced with a situation where the folder sound_rec It's empty, but there's a recorder in the voice recorder application, and it can happen for two reasons: either it's enabled to hide system files in the explorer, or it's saved to the cloud and deleted from the device. MIUI The default is hidden files that start with a dot, but the voice recorder folder is usually visible. However, if you use a third-party Explorer, the visibility settings may differ. In the standard Explorer, Xiaomi needs to click on the menu (three bars) and make sure that the item “Show hidden files” is activated. ES conductor or FX File Explorer, look for the Show Hidden Files switch in the display settings, and this will allow you to see all directories, including those marked as system directories. 👁️ Open the File Manager settings. 👁️ Find the "Display" or "View" section». 👁️ Activate the tick "Show hidden files». 👁️ Update the file list down. Another reason for missing files could be the activated Memory Cleanup feature. Xiaomi's aggressive optimization algorithms sometimes flag old audio files as junk if they haven't been listened to for a long time. Check the settings of the “Security” application» → «Cleanup» → «Settings" to exclude folder sound_rec clean-list. This will prevent the accidental deletion of important lectures or interviews.The Xiaomi Cloud Synchronization Ecosystem offers a convenient feature to synchronize voice recorders via Xiaomi Cloud.If this feature is enabled, your records are automatically uploaded to the cloud when connected to Wi-Fi. This means that files can be physically stored on the company’s servers, and only their cache or links are stored on the device. When cleaning the application cache, files can disappear from the local folder, remaining accessible only through the cloud interface. You can check the sync status in the Mi Account settings. → Mi Account. → Xiaomi Cloud → Application synchronization. If the switch opposite the Dictophone is active, then your records are duplicated on the network. It's a great way to secure data, but it takes care when you free up space: when you delete a file in the cloud, you delete it from your phone. You can upload records from the cloud to your computer without being tied to your phone using the web version of i.mi.com. Log in to your account, select the "Dictorphone" section, and download the files directly, which is especially useful if your phone is damaged or far away and you need access to the records urgently. However, it is worth remembering that free space in the cloud is limited, and overflowing storage will stop syncing new records. ⚠️ Note: When you reset your phone to factory settings without first uploading data from Xiaomi Cloud or local folder, all records will be irretrievably lost after erasing your account. Transferring recordings to a computer and other devices The most reliable way to transfer large volumes of audio is to connect your smartphone to your computer through a computer. USB-Cable. When you connect, select the mode of operation. USB «File transfer» (MTP) You can see a notification on your phone screen, and then you can see a disk on my computer that says your device's name, and you can go to Internal Storage. → MIUI → sound_rec, You can copy files by drag-and-drop. You can use the built-in Mi Drop (now ShareMe) function for wireless transmission or third-party solutions like Send Anywhere. These applications create a local Wi-Fi Direct network, allowing you to transfer files at high speed without using the Internet. This is ideal if you do not have a cable at hand, but you have a laptop or other smartphone. If you use the Google ecosystem, set up automatic folder sync. sound_rec Google Drive or OneDrive. In Google Drive, add a voice recorder to your backup list, and each new record will automatically upload to the cloud, where it can be retrieved from any device, and it creates a reliable backup without you. folder is empty or files are not readable One of the frequent problems is the situation when the recorder shows the presence of records, but in the folder sound_rec This may be because the records are stored in a specific format of the application database, rather than as separate audio files, which is often the case with older versions of the recorder or third-party modifications. In this case, try using the “Share” function inside the voice recorder application itself by selecting the desired track. If there are files but are not played on the computer, there may be no codecs for the format on the PC. AAC/M4A. Install a universal player, for example, VLC Media Player, which supports almost all audio formats without any additional settings, also check if the file is damaged: try opening it on the smartphone itself. If the phone has sound and the computer does not, the problem is Windows codecs. In rare cases, the path to the folder may change after a major system update. If the standard path doesn't work, search for files in Explorer. Type the extension into the search.m4a It's going to index the memory itself, and it's going to show the actual location of the file, and it's a universal method that works even when you change the structure of the system folders? In the standard application “Dictophone” from Xiaomi direct settings change the path of saving to the map SD However, some versions allow you to choose the memory card as the main storage in the general settings of the system, but this is unstable. SD-Why do the recorder records disappear after rebooting? This may be due to the operation of the function "Memory Extension" or aggressive cleaning of background processes. If the recorder application was killed by the system before the recording was completed, the file may not be saved. Also check if you don't want to record in the background in your battery settings. How to recover a remote record of a recorder? Immediately after deleting, check the Recycle Bin folder in the Dictator app (if any) or in Explorer. Files are stored there for 30 days. If the recycle bin is cleaned, recovery is possible only through specialized software for data recovery on the PC, and then only if new files were not written on top of it.
