Owners of Xiaomi, Redmi and Poco smartphones often face a situation where an important recording of a conversation, made automatically or manually, suddenly disappears from view, although there is definitely free space in the memory of the device. Finding these files can turn into a real quest, especially after operating system updates MIUI or switching to a new HyperOS shell, where folder structure sometimes changes without warning.
Understanding the logic of the Android file system, on which the Chinese giant devices are based, allows you to quickly find the right audio files without installing third-party software. In this article, we will analyze in detail the standard paths to directories, look at the features of hidden partitions and answer the question where exactly the conversations on Xiaomi are written depending on the firmware version.
Knowing the exact location of files is not only necessary for listening to them, but also for secure backup, so that when you accidentally reset your settings or flash it over, valuable information is not lost forever. Let's get a grip on the structure of the storage.
Standard paths to the folder with records in MIUI
By default, the Android system and add-on MIUI They use a certain directory naming logic to allow the user to navigate the files. The main storage of audio recordings created by the standard Phone application is usually located in the device's internal memory along the way. /MIUI/sound_recorder/call_rec. This is where all automatic and manual recordings are collected unless you have changed your default save settings.
However, depending on the regional firmware version (Global, China, EEA) and the Android version, the path may vary slightly. For example, on some models with a clean system or close to stock Android, files may lie in the standard /Recordings/Call folder. It is important to understand that accessing root directories often requires enabling the mode of displaying hidden files in the Explorer.
You can use a built-in file manager to quickly navigate to the desired partition. Open the Explorer app, select Internal Drive, and go to folders sequentially. If you use a third-party file manager with root rights, you can see all the system partitions, but you don't need to see them for standard tasks.
β οΈ Note: Do not delete files directly from system folders through root access without first copying.This may disrupt the call log or lead to errors in indexing media files.
The folder structure can only look confusing at first glance, and in fact, MIUI tries to group media files into types: voice recordings, call recordings, and notes are separated, all for user convenience and data security.
Alternative Locations and Cloud Services
If it's in a standard folder. call_rec If you didn't find the files you wanted, you should check the settings of the Phone app itself. MIUI 14 You can change your save path or use Xiaomi Cloud cloud storage, see if you have sync activated, which could move files to the cloud to save space on your device.
You should also pay attention to the folder. /MIUI/sound_recorder/ subfoldless call_rec. Sometimes, especially when recording through third-party voice recorder applications during a conversation (if this feature is supported), files can be saved to a common recording directory.m4a or.mp3, Unlike the standard.aac or.amr.
Another option is the use of SD-If you have a voice recorder or phone setting that says save to an external drive, look for a folder that has a similar structure, but is already at the root of the memory card. /SD Card/MIUI/sound_recorder/call_rec. This is a common situation where internal memory is overflowing.
π‘
Use file extension search. Type ".aac" or ".m4a" into the Explorer search bar to find all audio files on the device, regardless of their location in folders.
Don't forget Google Drive. Some users set up automatic uploading of folders with records. Check the Google Files app or Google account settings for enabled folder sync.
Audio file formats and their compatibility
Once you've figured out the paths, it's important to understand what kind of data format you're dealing with. The default MIUI system is most often.m4a (AAC) for high quality or.amr for space saving. The AMR (Adaptive Multi-Rate) format is the standard for mobile telephony, as it's optimized for human speech and takes up minimal space.
The problem is that not all media players on computers or other smartphones out of the box can play.amr files or specific.m4a containers with the AAC codec. If you transfer records to a PC for archiving, you may encounter a situation where the file is there but does not open.
To play such files on a computer, it is best to use universal players such as VLC Media Player or K-Lite Codec Pack. They contain all the necessary codecs and will easily play the recording of the conversation in any quality. On the smartphone itself, there are usually no problems, since the system player is sharpened for these formats.
| File format | Expansion | Sound quality | File size |
|---|---|---|---|
| Adaptive Multi-Rate | .amr | Low (voice only) | Minimum |
| Advanced Audio Coding | .m4a / .aac | High (HD Voice) | Medium. |
| MPEG Audio Layer 3 | .mp3 | High (third party annexes) | Big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big big |
| Waveform Audio | .wav | No compression. | Very big. |
If you need to transfer a recording of a conversation via a messenger (such as WhatsApp or Telegram), the.amr format may not be supported for playback in the chat itself, in which case the file will have to be converted or sent as a document first, rather than as audio.
How to find hidden records through a guide
Often users can't find a folder with records simply because it's hidden from view or the search is incorrect.The Explorer tool on Xiaomi has a convenient search feature that ignores the nesting of folders. Click on the magnifier at the top of the screen and type in the folder name. call_rec file extension.m4a.
Itβs also worth checking the hidden file display settings. Some versions of MIUI label system folders as hidden. To see them, open Explorer, click on the menu (three bars or dots) and make sure that the βShow hidden filesβ box is ticked. Then folders with a dot at the beginning of the title, such as.MIUI, appear in the directory list.
Another way is to sort by date, so if you know when the conversation took place, sort the files in the internal memory by the date of the change, and the record will have a time stamp that corresponds to the time of the call, which helps if you don't remember the exact file name or path.
βοΈ Search for lost record
Donβt ignore the Audio category in the main Explorer menu.There are often all the audio files sorted by type, which can make it easier to search if you donβt want to dig through the system folders.
Transfer and backup of records
Once you've found where Xiaomi's conversations are stored, it raises questions about whether they're safe. Your smartphone's internal memory isn't reliable storage: your device can crash, get lost, or get malfunctioned. Regular backups are the only guarantee of data safety.
The easiest way is to connect your smartphone to your computer through USB-Cable. Select file transfer mode (MTP) In the notifications, copy the folder. call_rec It'll take a few minutes, but it'll save gigabytes important information.
The alternative is to use cloud services, and you can set up automatic folder sync. /MIUI/sound_recorder/ Google Drive, Yandex.Disk or Dropbox. Many conductor apps, such as Mi File Manager or Google Files, have a built-in backup feature on a schedule.
β οΈ Note: When transferring files over Bluetooth, audio quality may be reduced if the system automatically recodes the file. USB-cable or Wi-Fi transmission to maintain original quality.
For professional use (for example, for journalists or lawyers), it is recommended to immediately after an important call to duplicate the file to an external drive or send yourself to the βFavoritesβ in Telegram, which is also cloud storage.
Solving problems with lack of records
Sometimes the recording function is enabled, but the files are not physically created. First of all, check the free space on the device. If the memory is 98-99% full, the system can block the creation of new files. Clearing the cache or removing unnecessary applications often solves the problem.
The second common cause is application conflict: If you have a third-party call recording app (like Call Recorder), it can intercept the audio stream by blocking the standard MIUI recorder. Try removing third-party software and checking the regular feature.
Also, check permissions. Go to Settings β Apps β All apps β Phone (or Recorder) β Application rights. Make sure you allow access to the microphone and memory. Without these permissions, recording is not technically possible.
Why can records disappear after an update?
If nothing helps, try to clean the Dictophone application data (without deleting the records if they are in the folder, but resetting the application settings) This will return the program to factory state and can eliminate software errors.

Regular check of the way of saving and availability of free space are the main conditions for stable operation of the call recording function on Xiaomi.
