Moving or Copying Files Stuck at 99% for a Long Time

"I've been experiencing issues with copying/moving large files (over 10GB) in Windows 10, specifically from or to an external USB hard drive. The transfer process usually runs smoothly until it reaches 99%, at which point it freezes and stops responding. After a few minutes, it completes the remaining bytes, but sometimes I'm left waiting for an extended period. I'm looking for solutions to this problem and want to know the underlying causes of this issue."

We believe that a stuck progress bar at 99% is the most annoying interface to encounter, only surpassed by the blue screen of death error.

When copying, transferring, deleting, or uploading/downloading files, it's common to get stuck at 99%. This issue can be frustrating, especially when dealing with large files. So, why does file transfer get stuck at 99%? The problem often lies in Windows 10's file system, which can cause the progress bar to freeze.

Quick Fixes for File Transfer Stuck at 99% in Windows 10

1. Zip the file before transferring it.

2. Keep only one antivirus software on your computer and uninstall the excessive ones to prevent them from draining your computer's resources.

3. Scan and remove suspicious malware and virus.

4. To optimize your computer's performance, clear your desktop by removing unnecessary documents, files, and icons. Additionally, avoid installing too many software applications on the C drive, as this can consume disk space and slow down your computer.

If you're still experiencing slow file transfer or deletion in Windows 10, don't give up. There are more effective methods to try that can help speed up the process.

Advanced Methods for Windows 10 Moving Files Stuck at 99% Issue

To resolve this issue, try the following practical methods to get it working again.

1. Free Up Space on Windows 10  

Insufficient memory space may be the reason why files are constantly copied and get stuck at 0, 10, 40, 60, 90, or 100 percent. Using a file cleaning program like Qiling CleanGenius can help free up system and large file space, thus speeding up and optimizing your computer's performance.

2. Optimize Hard Disk to Fix File Transfer Stuck at 99%

In addition to freeing up space to speed up data transfer, optimizing your hard disk can also help resolve the issue of files getting stuck at 99% by allowing your computer's drive to run more efficiently.

Step 1. To access the properties of any drive, go to "This PC", right-click on the drive you want to view properties for, and select "Properties" from the context menu.

Step 2. Click the "Tools" tab and choose "Optimize".

Step 3. Select all the drivers and click on "Analyze" or "Optimize".

3. Enable Write-Caching Settings in Windows 10/8/7

By disabling write-caching, you can optimize your hard drive or USB file transfer for faster speeds.

Step 1. To access the Device Manager, press the Windows key + X, and then select Device Manager from the menu that appears.

Step 2. In the Device Manager, find the specific drive with issues in copying files, and double-click on it.

4. Turn off Thumbnails in File Explorer 

Disabling thumbnails in File Explorer can help resolve issues like Win 10 file transfer getting stuck at 99 percent, 5 seconds remaining, and other problems. This is because generating thumbnails for each file can slow down the transfer process. By disabling thumbnails, you may be able to improve the speed of file transfers.

Step 1. Open File Explorer and click "View" on the top toolbar.

Step 2. On the drop-down pane, double click "Option" to open Folder Options Window.

Step 3. Click "View", and check "Always show icons, never thumbnails" > "Apply" > "OK".
