Check for malware and viruses
First of all, you need to perform a complete scan of your computer to make sure that it is free of viruses and malware. You can use your favorite third-party antivirus. Otherwise, the built-in Windows Protector tool is also a good choice. Here is how to use it.

Step 2: Go to “Update and Security” > “Windows Security”.
Step 3 Click on Protection against viruses and threats in the right pane.
Step 4. in the Windows Security Center pop-up window, click Run New Advanced Scan.
Step 5: Select “Full scan” and click “Scan now”.
After scanning, reboot your computer and try to transfer the file again. If an unexpected network error still occurs, you can proceed to the following method.
Disable the Windows Firewall
Windows Firewall can also interfere with file transfer. After all, it is a kind of network wall; thus, disabling the firewall can fix the 0x8007003b error.
Here is how you can disable the Windows Firewall.
- Click the Cortana button in the taskbar to open the application search window. Enter the firewall into the Cortana search box.
- Select this option to open the Windows Firewall Control Panel tab below.
- Click Enable or Disable Windows Firewall to open the Settings tab.
- On the Settings tab, select “Disable Windows Firewall” and click “OK”.
- Then restart the Windows operating system.
Disable Windows search service
Failure of Windows search service may also fix 0x8007003b error. To disable the Windows search service, press the Win + R keys to open Run.
In the “Run” section, type services.msc and press Enter to open the “Services” window.
Double-click Windows Search to open the window right below it.
In the Startup Type drop-down menu select Disabled.
Click Apply and OK to confirm the new setting and close the window.
Check the formatting
Windows and its memory have several formatting methods, for example: B. FAT32 or NTFS. These two methods have different limitations and some of them may cause this problem. You need to check the formatting of the target disk to which you copy the file. If it is FAT32, keep in mind that it only supports files smaller than 4 GB and will automatically close at the end of the copy. This only happens with one file larger than 4 GB. So if there are many files, everything will be fine.
Although this may seem like a much more complicated problem than it really is, just follow the above methods and everything will be fine.
