Changing a smartphone is always stressful, but not because of the device itself, but because of the fear of losing information accumulated over the years. Unlike iOS, the ecosystem Android provides the user with incredible freedom of action, allowing you to choose any file transfer channels. Many people prefer to use cloud storage or a direct Wi-Fi connection, but transferring data through a computer remains the most reliable and controlled method.
Using personal computer as an intermediary gives you full access to the file system of both devices. This is especially true when you need to transfer gigabytes of photos, video archives or heavy documents that are inconvenient to upload to the cloud due to Internet speed limitations. In addition, a cable connection guarantees the stability of the process without the risk of communication loss at the most crucial moment.
In this article we will analyze in detail all the stages of preparing and directly copying information. You'll learn how to properly configure USB operating modes, which file formats require special attention, and how to avoid common migration mistakes. Let's turn this process into a quick and understandable procedure.
Preparing equipment and checking compatibility
Before taking active steps, you need to make sure you have all the necessary tools. The basic element is quality USB cable. Smartphones often come with charging-only cables (with two wires) that do not support data transfer. You will need a certified cable that supports data transfer, preferably an original one from the manufacturer of your device.
Also make sure that the latest drivers are installed on your computer. In modern operating systems, such as Windows 10 or Windows 11, drivers for most Android devices are automatically installed upon first connection. However, for specific models from Xiaomi, Huawei or Sony you may need to install proprietary software to correctly recognize all memory sections.
☑️ Preparing for transfer
An important aspect is the state of the ports. It is recommended to use USB ports located directly on the motherboard (on the back of the system unit), since the front ports of the case may not provide enough power or have poor connections. If you are working with a laptop, make sure it is connected to power to avoid disconnecting while copying large amounts of data.
⚠️ Attention: Never use damaged cables with kinks or exposed wires. This can lead to a short circuit in the smartphone's power controller and failure of the device.
Setting the USB operating mode on smartphones
By default, when you connect an Android smartphone to a computer, the device goes into “Charge Only” mode. This is a security measure to prevent unauthorized access to your files when connected to other people's PCs. In order for the computer to see the internal memory or memory card, you must manually change this parameter in the settings.
After connecting with the cable, lower the notification shade on the phone screen. You will see a message "Charging via USB" or similar. Click on it to expand the mode selection menu. You need to select MTP (Media Transfer Protocol) or “File Transfer”. It is this protocol that allows the PC to see the folder structure and work with them as with ordinary removable media.
If the MTP item does not appear immediately, try unlocking the smartphone screen and confirming permission to access data in the pop-up window.
In some cases, especially on older versions of Android or specific firmware, you may need to activate the USB debugging mode. To do this, go to Settings → About phone and click 7 times on the “Build number” item to become a developer. Then in the menu For developers activate the switch USB debugging. This will give extended rights to manage the file system via a computer.
It is worth noting the difference between the modes MTP and PTP. PTP (Picture Transfer Protocol) mode is intended exclusively for working with photographs and is often used if the computer does not see the phone in MTP mode. If your goal is to transfer only a photo gallery, this mode can work where the usual one fails.
Copying multimedia and documents through Explorer
The simplest and most obvious way to transfer is to use the standard file manager of the operating system. After setting up MTP mode, your smartphone will appear in the “This PC” section as a separate drive. Open it and you will see the internal memory and, if present, the SD card.
Locate the folders containing the data you need. Main media files are usually stored in directories DCIM (photos and videos from the camera), Pictures (screenshots and images from applications), Download (downloads) and Music. Select the desired folders or files, right-click and select “Copy” or use the key combination Ctrl+C.
| Data type | Storage location | Recommended method |
|---|---|---|
| Photo and Video | /DCIM/Camera, /Pictures | Direct copying of folders |
| Documents | /Download, /Documents | Grouping by file type |
| Music | /Music, /Android/media | Copying with tag checking |
| Messages/Calls | System database | Specialized software |
Go to the folder on your computer where you want to temporarily save the data. Insert files (Ctrl+V). Wait until the copying process completes. The transfer speed depends on the version of the USB port (2.0, 3.0, 3.1) and the recording speed of the smartphone’s internal memory. After successful copying to PC, disconnect the old phone and connect the new one.
On a new device, repeat the procedure for connecting and setting up MTP mode. Open the memory of the new phone and paste the copied files into the appropriate directories. It is important to maintain the folder structure, especially for media files, so that the gallery of the new smartphone correctly indexes them and displays them in the general list.
Use of specialized software for complete migration
If manual copying of folders seems too labor-intensive for you or you need to transfer system data, such as contacts, call history and SMS messages, it is better to use specialized software. Standard Windows Explorer does not have access to application databases, so this data will remain on the old device if manually copied.
There are many assistant apps, such as Moborobo, Wondershare MobileTrans or proprietary utilities from manufacturers (for example, Samsung Smart Switch for PC). These apps automatically detect connected devices and offer to select categories of data to transfer. They are able to convert database formats, making them readable on a new device.
Why are contacts not copied through Explorer?
Contacts in Android are not stored as separate files, but in a single SQLite database inside the system partition, access to which is closed to the average user without root access.
The process of working with such software usually looks like this: installing the app on a PC, connecting both phones at the same time (or one by one with intermediate saving of a backup on the PC), selecting the data type and starting the process. The app itself will create a backup copy on your hard drive and deploy it to the target device.
⚠️ Attention: When using third-party software, carefully read the license agreement. Some apps are shareware and may limit the number of transferred contacts in the demo version.
Particular attention should be paid to transferring messenger data. WhatsApp, Telegram and Viber store correspondence history in encrypted form. To transfer them, you often need to create a local backup copy within the application itself before connecting to a computer, or use the “Transfer Chats” function, available in the settings of the messenger itself, which can be initiated through the PC version of the assistant app.
Working with the file system and hidden folders
When working through a computer, you get access not only to user files, but also to system directories that are hidden on the smartphone itself. At the root of the internal memory there are often folders with application names, for example, Android/data or Android/obb. The game cache, additional application files and settings are stored here.
Copying the folder obb may be critical for heavy games. If you simply install a game from Google Play on a new phone, you will have to download gigabytes of data again. By transferring this folder via your computer, you will save traffic and time. Just copy the content Android/obb from the old device and paste it into the same directory on the new one.
However, you should be careful with the folder data. It stores specific application settings tied to a unique device identifier or application version. Blindly copying this folder can lead to conflicts and application crashes on a new smartphone. It is recommended to transfer only those subfolders that clearly contain user content (for example, downloaded maps in the navigator).
Transferring the OBB folder allows you to avoid re-downloading game resources, but requires strict adherence to the directory structure on the new device.
It is also convenient to clean your smartphone of debris through a computer before selling or transferring it. You can visually estimate the size of folders, find duplicate photos or forgotten video files taking up space. Deleting files via a PC is faster and more reliable than through the phone's built-in file manager.
Completing the process and checking data integrity
After all files have been copied, you cannot simply pull out the cable. This can lead to file system corruption and loss of data that is still being written to the cache. On the computer in the tray (near the clock), find the USB device icon and select the option Safely remove device. Wait for a message indicating that the equipment may be turned off.
On your smartphone, also make sure that the data connection indicator is off. After physically disconnecting the cable, perform an initial test on the new device. Open the gallery and make sure all photos are showing. Launch the file manager and check for documents in the folder Download.
If you transferred music, you may need to restart the media server or the smartphone itself for the playlists to be updated. Sometimes a new phone doesn't see the tracks right away because the media content database hasn't scanned the new files yet. In this case, simply turning off and on the device will help.
⚠️ Attention: If, after transferring the data, the disk space on the new phone is not freed up or is displayed incorrectly, try clearing the cache of the “Media Storage” application in the application settings.
Do not forget to delete the copied temporary files from the computer’s hard drive so as not to take up space. Now you have a fully configured new smartphone with all the important data, and the old device is ready to reset or sell.
Frequently asked questions (FAQ)
Is it possible to transfer installed applications (APK) through a computer?
Yes, you can copy APK installation files if you have them Yes, or use special apps to backup installed applications (require root access or debugging activation). However, it is easier to download them again from Google Play, since direct copying of application folders often does not work due to differences in signatures and system versions.
What to do if the computer does not see the phone in MTP mode?
Try replacing the USB cable with a known good one. Check the Windows Device Manager: if there is a device with a yellow exclamation mark, try updating the driver manually by selecting “MTP USB Device” from the list of standard Microsoft drivers.
Is it safe to transfer passwords and banking application data via PC?
No, banking application data and password managers are usually encrypted and tied to the specific device's hardware key (Keystore). They are not transferred through the file system. You will have to log in to them again on the new device.
How to transfer Chrome browser history via a computer?
The most effective way is not through files, but through synchronizing your Google account. Log in to your Google account in the Chrome browser on your new phone, and all history, bookmarks and passwords will be pulled up automatically from the cloud.
Will the data on the old phone be erased after copying it to a PC?
No, the copying process (Copy/Paste) creates duplicate files. The data on your old phone will remain completely safe. If you want to free up space, you will need to delete them manually after checking the success of the transfer.
