Mi and Redmi smartphone owners often face the need to find the physical location of their records in the file system, not just out of curiosity, but to create full backups or restore data after a system failure. Standard methods of synchronization with the Mi Cloud are convenient, but do not always give access to the raw data stored inside the device.
Finding the answer to the question of where the notes are in Xiaomi’s memory leads users to system partitions that are restricted by super-user rights. Application database files are not in the open folder Documents or Downloads. They are hidden deep in the structure of the Android operating system, which provides basic protection against accidental deletion or theft of information by unauthorized applications.
In this article, we will take a closer look at the storage structure of the standard Notes app, learn the exact paths to database files, understand the difference between on-premises storage and cloud synchronization, and explore how to extract information using USB debugging and tools for converting a database into readable text.
Storage architecture in MIUI and HyperOS
The MIUI operating shell and the new HyperOS use the standard Android file system, but with additional layers of security. Any application, including the Notes system, allocates itself an isolated memory area. This space is not readable by other programs without special permissions or root rights. This is where all user information is generated and stored in a closed container.
The data in Xiaomi notes is not stored as separate text files with the.txt extension. All information, including text, lists, sketches of figures and metadata (date of creation, tags, shortcuts), is written into a single database. Usually a SQLite file, which allows the system to quickly index content and instantly display search results for keywords.
⚠️ Warning: Direct editing of database files through root-enabled file managers can result in total database corruption and loss of all records!
System architecture involves a division into a user partition and a system partition, and even if you see an application folder in a Explorer, real data is often deeper, and understanding this structure is critical for those who are engaged in data recovery or transferring information between devices manually, without using a Mi Account.
💡
Use the “Export Note” function inside the app itself to save individual entries in.txt or images if you need access to content without root rights.
The exact path to database files
To find exactly where Xiaomi notes are in the phone’s memory, you need to go to the root directory of internal memory. The path is standard for most Android versions, but may vary slightly depending on the firmware version.
/data/data/com.miui.notes/databases/
It's in this directory that you'll find a file that's usually called note.db or note.db-journal. Note.db is your database with all the texts. The file with the -journal extension is a temporary transaction log and the system needs to restore data integrity in the event of a power failure during the recording.
To get to this folder, the default file manager will not be enough, as it does not have access to /data/.
- 📱 File Manager with support for root access (e.g. Root Explorer, MiXplorer or Root Explorer) MT Manager).
- 🔓 Unlocked bootloader and installed SuperSU or Magisk (root rights).
If you use ADB, the command to go to the desired directory and output the list of files will look like this:
adb shell
cd /data/data/com.miui.notes/databases/
ls -lOnce you run the ls -l command, you will see a list of files. You can copy the database to your computer by adb pull /data/data/com.miui.notes/databases/note.db. This will create a copy of the file in the ADB tool folder on your PC.
How to Open and Read a Database
Once you've copied a note.db file from your smartphone's memory to your computer, the question is, how do you open it? Because it's SQLite, Windows Notepad will only show you a set of unreadable characters and rare text patches. You need specialized software to properly display structure and content.
One of the most popular and free tools is DB Browser for SQLite, which allows you to open a database file, see a table with records and export them in a readable format, and the viewing process is as follows:
- Run DB Browser for SQLite on your computer.
In the table that opens, you'll see columns. text_content The title column stores the title, but the text can be stored in coded form or broken down. If you see strange characters, maybe encryption or specific encoding is used. MIUI.
⚠️ Note: Some versions of HyperOS firmware can encrypt database content by linking decryption keys to a specific hardware ID In this case, a simple copy of the file to another phone without unlocking may not give access to the reading.
For advanced users who are familiar with SQL-Inquiries are available to the "Fulfilled" tab SQL". It can only sample the data you need, like a request. SELECT title, content FROM note WHERE create_time > 1600000000; This will only allow you to display notes that were created after a certain date (in Unix-time format).
Using ADB to extract notes
If getting root rights on your Xiaomi device is impossible or undesirable, the only legal way to get files from the system folder is to use debugging. USB. This method requires a connection to a PC, but does not require unlocking the bootloader. /data/data/ You will need to use root, so you will need to use the standard ADB Without root, we can only use backup.
The adb backup command allows you to back up the Notes app along with the data.
adb backup -noapk com.miui.notesOnce you enter the command, you will see a request on your smartphone screen to confirm the backup, set the password (you can leave it empty) and click "Create a backup." The backup.ab file will appear on your computer. This file contains the packaged application data.
To unpack the.ab file and get to the database inside, you will need the Android Backup Extractor utility (abe.jar).
- 📂 Download the abe.jar file.
- 💻 Open the command line in the folder with the utility.
- 🔄 Follow the command: java -jar abe.jar unpack backup.ab backup.tar.
- 📦 Unpack the.tar archive with any archiver (7-Zip, WinRAR).
Inside the unpacked folder, you’ll find the structure of apps/com.miui.notes/f/note.db. This method often works better than direct file copying, as the system itself correctly closes the connections to the database before packaging.
☑️ Pre-extraction verification
Cloud Storage and Synchronization
When it comes to where the notes are, you can't ignore the cloud aspect. For many Xiaomi users, the main storage location is the Mi Cloud server. Unlike local files, which are difficult to access, cloud data can be viewed from any computer through a browser.
To access your records, go to i.mi.com and log in to your Mi Account. In the cloud service interface, select Notes, which displays a full copy of what's on your phone if sync is enabled, and is the easiest way to recover text if your phone is lost or broken.
Compare local and cloud storage:
| Parameter | Local storage (Memory) | Cloud Storage (Mi Cloud) |
|---|---|---|
| Availability | Only on the device. | From any device with the Internet |
| Security | Depends on phone protection. | Account and 2FA protection |
| Risk of loss | High when broken. | Minimum |
| Volume | Limited to phone memory | Limited by cloud fare |
However, there is often a recycle bin in the cloud where deleted files are stored for up to 30 days, a unique opportunity to recover data even if you have cleared it in the app.
Recovery of deleted notes
If you accidentally delete important information, the recovery process depends on whether the data has been overwritten. In the Android file system, when you delete a file, only the space it occupied is marked as free, and the data itself remains on the disk until the system writes new information on top of it.
To recover deleted databases or individual records from memory, Xiaomi can use specialized software for PCs such as Dr.Fone, Tenorshare UltData or DiskDigger (for Android), which scans internal memory for SQLite file signatures.
Algorithm of actions in recovery:
- Stop using your phone immediately so you don’t overwrite memory sectors.
- Connect the device to the computer.
- Run the recovery program and select the scan mode "Deep Scan".
- After analysis, filter the results by the type of files "Database" or "Documents".
Why is recovery not always successful?
It's also worth checking the.Trash or Recycle Bin folder inside the Notes app itself. In modern versions of MIUI, deleted items don't disappear immediately, but move to temporary storage for 30 days, the first item to check before running complex recovery procedures.
💡
Regularly exporting important notes to PDF or TXT format and storing them on external media is the only 100% reliable way to protect against data loss.
