Xiaomi smartphone owners often face the need to expand built-in storage, especially when the standard 32 or 64 gigabytes becomes insufficient for photos, videos and applications. the Redmi 7 model, despite its age, remains a popular device, and the question of how to find a memory card on the android xiomi Redmi 7, does not lose relevance. Users often get confused in the file system or can not detect the physical slot, which causes panic and false opinion about the breakdown of the gadget.
Searching for a drive can involve both detecting a physical connector in the device body and displaying files in the MIUI software shell. In the first case, it is important to know the design features of a particular modification of the smartphone so as not to damage the tray when extracting. In the second, you need to understand the logic of the file manager, which by default can hide system partitions or require manual activation of external media display.
In this article, we will take a closer look at all aspects of working with MicroSD on your device, we will look at the physical location of the slot, the software paths to files through standard and third-party tools, and also touch on the important nuances of formatting. If you just purchased a card or encountered a reading error, this guide will help you understand the situation without going to the service center.
⚠️ Attention: Before any manipulation with the extraction of the tray SIM-Make sure the smartphone is turned off or at least disconnected from the charger to avoid short circuits of contacts.
Physical search for a memory card slot
The first step is always to check the hardware. On the Redmi 7, the memory card slot is located on the upper end of the case, which is a hallmark of many Xiaomi budget models of the period. Unlike more modern flagships, where trays can be sealed differently, it uses a classic retractable mechanism.
To extract the tray, you'll need a special metal clip that comes with the kit, or a regular stationery clip that is straight-lined. You'll need to find a circular hole next to the elongated tray. You'll need to tap it lightly and push it out, and it's important not to confuse the hole with the noise-cancellation microphone, which is also on the top end, but has a smaller diameter and doesn't respond to pressing.
The design of the tray in Redmi 7 is a hybrid scheme, which means that the user has two options for installation:
- 📱 Two nano-SIM cards simultaneously;
- 📱 One nano-SIM card and one microSD memory card.
Use two. SIM-If you're critically important with two SIMs, you'll have to give up the expansion or use cloud services. When you install the memory card, make sure the gold contacts are down and the bevelled angle matches the tray shape. Do not use force when closing - the tray should enter smoothly.
Setup and formatting through the Android system
After the card is physically installed, the system must automatically identify the new media, usually a notification appears on the screen that a new one has been discovered. SD-However, in order for a device to work fully with files, it often requires pre-formatting, a process that removes all data from the drive and creates a file system that is understandable for Android.
To start, go to the settings menu. You need to find the storage section. The path may vary slightly depending on the version of the MIUI shell, but most often it looks like: Settings → Memory or Settings → Phone → Storage. In this menu, you will see a graphical display of internal memory and external storage.
Click on your memory card name. The system will suggest several actions. If the card is new or has been used on another device, you will need formatting. Select the option "Clear" or "Format". The system will warn you about the loss of data, confirm the action. Once the process is complete, the card will be ready to write files.
☑️ Checking the connection of the card
There is also the possibility of using the card as part of internal memory, although on older versions of Android this feature could be hidden by developers. If you want to install applications on the map, look for the item "Use as internal storage", which will increase the speed of programs, but make the card unreadable on other devices without re-formatting.
⚠️ Note: Do not remove the memory card while writing data or running applications installed on it. This can damage the file system and lose information without the possibility of recovery.
Searching for files through a standard conductor
When the map is formatted, the question is, where are the files now? The standard tool for managing files in the MIUI shell is called Explorer, and you can find it on your desktop via the folder icon, which is the main tool for navigating the directory structure of your smartphone.
When you launch the app, you will see the top bar with categories (Images, Videos, Documents) and the Device section. It is in the Device section that all the connected drives are displayed. Internal memory is usually referred to as an “Internal Storage” or “Internal Storage” and external memory is referred to as an “Internal Storage” or “Internal Storage” card «SD-map or lettering, for example, /storage/sdcard1.
The folder structure on the memory card is organized logically, system applications create their directories with names corresponding to the packages of programs. WhatsApp/Media, And the downloaded files from the browser are in the Download folder, and understanding this structure will help you quickly find the document you want.
Hidden system folders
If you can't see the card in the explorer, try rebooting the device. Sometimes the download drivers don't have time to initialize the external media when you turn on. Also check if PC-only mode is enabled in the USB settings, although this affects mainly cable connection.
Use of Third-Party File Managers
Xiaomi’s standard Explorer is functional, but sometimes users prefer more advanced tools. Third-party file managers such as Total Commander, ES Explorer or FX File Explorer provide more detailed access to the file system, allowing you to see hidden file attributes, work with archives, and even connect to network storage.
When you install an app like this, it'll ask for permission to access the storage, and once you've granted permission, you'll be able to see the full path to the memory card. In Android terms, external drives are often mounted along the way. /storage/XXXX-XXXX, where X is a unique identifier. Knowing the exact path is useful when setting up torrent clients or media players.
The advantage of third-party managers is that they can rename batches, copy more easily, and have built-in tools to analyze your space, so you can quickly determine which files are taking up the most space on your MicroSD, and delete the extra.
| Function | Standard MIUI conductor | Third-party managers |
|---|---|---|
| Access to hidden files | Limited. | Complete. |
| Work with archives | Basic | Expanded |
| Network Storage (NAS) | No. | There is. |
| Interface. | Simplified | Customizable |
The use of alternative software is especially important if the standard application is unstable or does not display file name encoding correctly, which is often the case with files created on Windows computers.
Connecting to a computer to view files
The most convenient way to find and copy a large number of files is to connect your smartphone to your computer. USB-cable, because cheap analogues can only support charging and do not transfer data. Connect the device to the PC port and unlock the smartphone screen.
After you connect to the notification curtain, you'll see a message called "Charge via USB." Click on it and select File Transfer or MTP. The computer will define the phone as a removable disk. My computer will have a new device that will display both internal memory and memory card as a separate logical disk.
💡
If your computer can’t see your phone, try another one. USB-port (preferably behind the system unit) and make sure that the phone is debugging on USB or data transfer mode, not just charging.
You can do any type of work through Windows interface: copy, delete, create folders. The data rate will depend on the class of your memory card and the version of the USB port. Once you're done, be sure to use the Safe Device Removal feature in Windows before you turn off the cable.
If your computer only sees internal memory but doesn't see the card, check your connection settings. Sometimes you need to re-insert the card when the cable is connected to re-mount the partitions, and the problem may be the ADB or MTP drivers on the computer itself.
Solving problems with map display
It's not uncommon for a card to be installed but not seen by the phone, and the first cause may be contamination of the contacts, wipe the golden part of the card with a soft dry cloth or a weasel, and contact oxidation is a common problem with prolonged use or moisture.
The second reason is the file system. Android natively supports FAT32 and exFAT. If your card is formatted in NTFS (Windows standard), the phone may not recognize it without installing special plugins, in which case you will need formatting via a PC or directly in the menu of the smartphone.
It's also worth checking the physical integrity of the tray. In the Redmi 7, the contacts in the back of the socket can oxidize or bend. Try cleaning the socket carefully with compressed air. If the map is not readable on any device, it may have failed.
⚠️ Warning: If your memory card is constantly falling off or requires formatting every few minutes, this is a sure sign that it will soon fail.
💡
Stable operation of the memory card depends not only on its quality, but also on the state of contacts in the tray. SIM-Maps and Relevance of Smartphone Software.
