Users of Xiaomi, Redmi and Poco smartphones often face the need to retrieve or listen to an important conversation they’ve had before, ranging from clarifying order details to fixing fraudulent activities, but when they open a standard voice recorder or file manager, many people can’t find the right audio file immediately, because MIUI or HyperOS hides them in specific directories.
In this article, we will discuss in detail where exactly the physical tracks are stored on the device, how to find them through the computer and what to do if you are enabled to sync with the cloud. Understanding the structure of folders will allow you to quickly manage the archive of calls, free up space or transfer important data to another device without losing information.
Note that file layouts may vary slightly depending on the operating system version and regional settings. We will look at universal ways that are relevant for most modern models, and also touch on the nuances of working with access rights in new versions of Android.
Physical location of files in internal memory
By default, all audio recordings created by the standard Phone application are stored in the internal memory of the device, which provides quick access to files and no delays in recording, since the built-in drive is usually faster than memory cards, and the system creates a separate hidden or system folder for them, accessed through the file manager.
To find the records manually, you need to open the Explorer app (or Files) and go to the root directory. → MIUI → sound_recorder → call_rec. This is where all the files in the format are located.mp3 or.aac, sorted by date of creation.
If you connect your smartphone to your computer through USB-cable, the navigation will be similar» (MTP) And on the phone, you'll see the same folders, and it's a convenient way to copy the entire conversation archive to your hard drive for long-term storage.
💡
Use the “Date of Change” sorting mode in the file manager to find fresh entries faster without manually scrolling through the entire list.
It's important to understand that deleting files from that folder through Explorer is like removing them from the phone's call list, and the system doesn't store backups of that data locally unless you set up sync yourself.
Search through the application "Dictophone" and "Phone"
You don't have to go to system folders every time you listen to a record. The built-in MIUI applications provide a user-friendly interface for managing your archive. There's a separate tab or button in the Phone app that allows you to see a list of all recorded conversations tied to specific contacts or numbers.
The Dictophone app also has a section for recording calls, and here the functionality is extended: you can edit audio, cut out unnecessary pauses or add tags. To navigate to the desired section, click on the menu (three dots or strips) and select "Call Records".
- 📞 Direct access: Open a call log, click on a specific number, and if the record exists, an audio cassette icon will appear next to the call date.
- 🎚️ Editing: The Dictator app has a track cropping feature available, which is useful for removing silence at the start of a conversation.
- 📤 Export: From both applications, you can send a file via instant messengers, mail or save to the cloud using the Share button».
The use of standard interfaces is preferable for daily tasks, as it ensures that you do not delete system files accidentally, and it also displays the recording duration and date, which makes it easier to search.
Synchronization with Mi Cloud and Google Drive
For those who are worried about data safety when a smartphone is lost or broken, setting up cloud sync is critical. Mi Cloud is a native cloud storage from the manufacturer, which is deeply integrated into the HyperOS shell. It allows you to automatically upload recordings of conversations to the server.
To activate this feature, go to Settings → Mi Account → Mi Cloud → Recorder and enable sync. Please note that free space is limited to 5 GB, and audio files can quickly fill it, in which case the system will stop downloading new records until you vacate space or purchase a subscription.
What happens when the cloud overflows?
The alternative is Google Drive. In the Dictator settings, you can choose a way to save copies. This is convenient if you are already using the Google ecosystem for other data. However, automatic downloading can consume mobile traffic, so you should only set up sync via Wi-Fi.
⚠️ Warning: When you reset your phone to factory settings without prior synchronization, all local records will be permanently lost. Always check the status of the cloud before formatting.
Configure recording parameters and formats
The quality and format of the files you save directly affect the space and listening experience. In the Dictator settings, you can choose the priority format: MP3 provides better compatibility with other devices, and AAC or AMR saves space through more efficient compression.
It also configures the sound source. The call recording mode is typically called "Telephone Conversation," which optimizes the microphones to capture the voice of the other person and your voice simultaneously, cutting off external noises. If you choose "Normal," the recording can only be done from one microphone, which will worsen the legibility.
| Parameter | Description | Recommendation |
|---|---|---|
| Format | MP3, AAC, AMR | MP3 for archive, AAC for savings |
| Quality. | Low, Standard, High. | Standard (balance of size and quality) |
| Source | Microphone, Telephone. | Phone only for calls |
| Numbering | Addition of number to name | Enable for quick search |
Enabling the option “Add phone number to file name” makes navigation in the folder much easier call_rec. Instead of abstract names like 20231025_143000.mp3 You will get files with names like 20231025_143000_+79990000000.mp3.
💡
The best choice for most users is the AAC format with Standard quality and included file numbering.
Access issues in Android 11, 12, 13 and later
Starting with Android 11, Google has imposed strict restrictions on applications’ access to the file system of other applications (Scoped Storage), which means that some third-party file managers may not see the folder. MIUI/sound_recorder or show it empty even if the files are there.
To solve this problem, use only Xiaomi’s Files Explorer or the official Files by Google, which have the necessary system permissions to display the contents of system folders. Third-party programs like Total Commander may require special access configuration through system dialogue.
- 🔒 Restriction of rights: The system blocks direct access to folders Android/data System audio archives for third-party software.
- 📂 Solution: Use built-in Explorer to move or copy files, and then open them with the right player.
- 🔄 Update: In the latest versions MIUI Access to folders has become more stable, it is recommended to update the system.
If you're trying to find records through a PC connection and you see an empty folder, try rebooting your smartphone with the cable connected.Sometimes the MTP driver doesn't update the file list in real time.
⚠️ Warning: Do not try to obtain Root rights solely for the sake of accessing folders.This will disrupt banking applications and may cause update system failure.
Archive transfer and backup
Regular backup of conversation records is an important part of digital hygiene, especially if the data is legally binding, and simply moving files to a memory card may not be enough, as changing the phone may cause path settings to get lost.
The most reliable method is to use the method of "cold" copying to the computer. Periodically connect the smartphone over the cable and copy the contents of the folder. call_rec This will create a physical copy independent of the account or cloud services status.
☑️ Checklist of backups
You can use synchronization applications like Resilio Sync or Syncthing to automate the process, and they can set up automatic transfers of new files from the call record folder to your computer or computer. NAS-server immediately after their arrival.
When transferring to a new device, Xiaomi is enough to restore the folder structure or use the “Mi Mover” function, which when transferring data from the old phone to a new one often captures the system settings of the recorder, including linking records to contacts.
