Xiaomi smartphone owners often face the need to move important data or recover accidentally deleted information after a system reset. Redmi 5, despite its age, remains popular due to its stable operation and availability, however, finding system files in the MIUI shell can cause difficulties for inexperienced users. Standard methods of viewing through the file manager often do not show hidden system folders where the application databases are physically located.
Understanding the structure of the Android file system is essential for deep work with the device. Unlike simple multimedia files, the text records of the Notes app are stored in a secure part of internal memory. Access to this data is limited by access rights, which requires certain actions to extract or back up to an external medium.
In this article, we will take a closer look at the logical and physical paths to note files, how to find backups, where the bulk of the data is stored, and what tools will help keep the information safe, and how to work with the SQLite database used by Xiaomi’s system services to store text information.
Logical Structure of Data Storage in MIUI
The Android operating system that runs Redmi 5 uses a strict directory hierarchy to isolate these applications. Each app installed receives its own unique identifier and dedicated memory area. For the standard Notes app, this means that all the texts, shopping lists and voice recorders you create are stored in a special directory, which is accessed by default from normal viewing.
Logically, the user sees only the application interface, but the physical data is a set of database files. In the MIUI shell, the system package often responds to work with notes, which may differ from the standard Google Keep or third-party counterparts. The database usually has the extension.db or.sqlite and contains tables with text, creation time and formatting parameters.
It is important to distinguish between local storage and cloud sync. If your Mi Account settings are synced, a copy of your records is sent to the manufacturer's servers. However, the local copy always stays in the device's memory until manual deletion or Factory Reset. Local files are the most important for data recovery without access to the Internet.
⚠️ Warning: Direct editing of database files without relevant knowledge can result in complete loss of all records and inability to run the application.
💡
Always create a complete copy of the data section before any manipulation of the database system files.
Physical path to database files
To find out where the notes files on Redmi are located. 5, You need to access the root directory of internal memory. The standard path for system data applications in Android looks like this. /data/data/. However, this folder is only available to users with Root (superuser) rights. Without obtaining advanced access rights, you will not be able to see the contents of this directory through a standard explorer.
The Notes app in the MIUI shell often uses a package called com.miui.notes or similar variations depending on the firmware version. The full path to storage will look like this: /data/data/com.miui.notes/databases/. Inside this directory are files with names like note.db, note.db-wal and note.db-shm. Files with extensions -wal and -shm are temporary and are necessary for the proper operation of the database journaling mechanism.
If superuser rights are not available, users often look for alternative export routes. Some firmware versions allow local backups to be created via Recovery Recovery menus or special PC utilities, in which case files can be archived in /MIUI/backup/AllBackup/, from where they can already be copied to a computer without Root permissions.
What to do if the /data/data folder is empty?
The contents of the files found will require specialized software. A regular text editor will show only a set of unreadable characters, since the data is structured in a binary SQLite format. You need to use database programs that are able to interpret this structure and display text in a readable form.
Use of Root Rights to Access
Obtaining superuser (Root) rights on Xiaomi Redmi 5 gives full access to the file system, including hidden directories of system applications. This is the only way to directly copy the note database file for subsequent analysis or transfer to another device, saving the entire history. The rooting process is usually done by unlocking the bootloader and installing a modified TWRP recovery image.
Once you install a rights manager like Magisk or SuperSU, you can use Root-enabled file managers like Root Explorer or MT Manager, which allow you to not only copy files from protected partitions, but also change their permissions. When copying a database, it is important to save all three associated files (.db, -wal, -shm) to ensure the integrity of transactions.
There is a risk of system failure if incorrect intervention is made, changing file owners or access rights (chmod/chown) can cause the Notes app to stop running or to give up errors when saving, so it is recommended to back up the original files to a secure location, such as an SD card, before any changes.
☑️ Checking before accessing system files
It’s worth noting that Root rights can affect some of the more secure banking applications and services. On Redmi 5 with Snapdragon 425 processor, resources are limited, and unnecessary background security checks can slow down the interface.
Alternative methods of export and synchronization
If it seems too difficult or risky to get Root permissions, there are regular ways to save data. MIUI offers a built-in sync mechanism with the Mi Cloud. By activating this feature in the account settings menu, you automatically upload all your records to the server, which allows you to restore them to any device just by logging into your Mi Account.
For local export, you can use the Send function within the application itself, and if you select one or more notes, you can send them as a text file or image via Bluetooth, Email, or messengers, which is convenient for transferring a small amount of important information, but is not suitable for migrating the entire database at once.
Also worth considering is the use of third-party backup apps that don’t require Root, but use ADB (Android Debug Bridge) debugging mechanisms. By connecting Redmi 5 to a computer and enabling USB debugging in the Developer Menu, you can upload the app data with the adb backup command. However, on modern Android versions, this method is often limited and may not save data from some system applications.
⚠️ Note: When using cloud sync, make sure you have free space in Mi Cloud storage, otherwise new notes will not be saved.
Analysis and recovery of data from the database
Once a database file (like note.db) is successfully retrieved, it's the contents of the database, and as mentioned earlier, it's SQLite. DB Browser for SQLite or SQLiteStudio. They let you browse tables, run tables, run them. SQL-request and export data to readable formats, such as CSV or HTML.
Inside the database, the text of notes is usually stored in a table called note or content. text_data, If the notes were deleted by the user, but the database file was not overwritten by the new data, there is a possibility of their recovery. In SQLite, deleting the record often marks the place as free, but does not erase the information instantly.
Recovery of deleted records from a corrupted or cleaned file may require specialized SQLite recovery utilities that scan raw file data for text signatures, and the success of this operation depends on how much memory was used after the notes were deleted, and the new data could overwrite the sectors where your information was stored.
💡
The most reliable way to save notes is to regularly export to a format that does not depend on the version of the application, for example, in PDF or TXT.
Comparison of Storage Methods and Risks
The way you work with notes on Xiaomi Redmi 5 depends on your goals: whether you need a one-time archive download or constant synchronization. Each method has its advantages and disadvantages that you should consider. Below is a comparative table of basic approaches.
| Method | The need for a Root | Risk of data loss | Usability |
|---|---|---|---|
| Direct access to /data/data | Yes. | High (User error) | Low (requires skills) |
| Mi Cloud Synchronization | No. | Low (depending on the server) | High (automatically) |
| ADB Backup | No (PC needed) | Medium (Android restrictions) | Average. |
| Exports through the annex | No. | Low. | High (manual) |
The greatest risk of loss of information occurs when you reset your settings to factory without first synchronizing.In this case, the /data partition is completely cleared, and file recovery becomes almost impossible without professional hardware. Therefore, relying only on local storage on Redmi 5 without duplication is dangerous.
Using third-party notebook apps from Google Play can be an alternative: They often have their own cloud-saving mechanisms or make it easy to export data in universal formats. However, the MIUI Notes system app is deeply integrated into the shell, supporting desktop widgets and fast entries in the lock screen, making it more convenient for everyday use.
