Best Ways To Fix The Unspecified Error When Copying File or Folder on Windows 10/11

Bumped into the “Unspecified error” while trying to copy files or folders from one place to another. You are not alone. Many Windows 11 and 10 users have faced this error. In this post, we’ll look at ways you can fix the issue. But, before you try out the steps mentioned in this post, we request you take a backup of the necessary files.

What Causes Unspecified Error in Windows –

  • The target disk is corrupted or the file or folder is encrypted.
  • Insufficient disk space.
  • You don’t have ownership of the file or folder.
  • File system limitations.
  • The target disk is write-protected.
  • There is a conflicting application is running on your computer.

1. Convert FAT32 to NTFS

If you have a file with the FAT32 file system and you are trying to transfer that, you might run into issues. For instance, if the file you are trying to transfer is larger than 4GB, the “Unspecified Error” may surface as the file size limit of each file is 4 GB.

1. In the Windows search bar, type cmd and click on Run as administrator from the right-hand side.

2. When the Command Prompt opens, type convert e:/ fs:ntfs and press Enter

You can even FAT32 to NTFS using a third-party tool like EaseUS Partition Master.

A little later in the post, we’ll also see how you can use EaseUS Partition Master to extend partitions which is also one of the workarounds to fix the issue.

2. Compress The File

Sometimes when the file or folder is large, the error in question may surface. Here you can try to compress the file and then try and perform the transfer. Additionally, you can even check the integrity of the file or folder you are copying using third-party file copy software.

1. Right-click on the problematic file/folder.

2. Click on Send to and then click on Compressed (zipped) folder

Want to give some other feature-rich file compression software a try, here are some options you can consider.

Now try copy-pasting this zipped file. This should hopefully resolve the issue and you will be able to successfully transfer files.

3. Use A Third-Party Tool To Extend the Partition

Insufficient disk storage is often the reason why the “Unspecified error” occurs when copying files and folders. Here you can try and extend the hard drive partition size of the disk that is creating issues. For this, you can use disk partition software.

Let’s take an example of EaseUS Partition Master and see how easy it is to extend partition –

1. Download, run, and install EaseUs Partition Master.

2. Locate the problematic partition and click on Resize/ Move from the right-hand side.


3. Extend your partition by dragging the slider to the right.

5. Click on OK.

4. Re-register jscript.dll & vbscipt.dll

To deal with the “Unspecified error” when trying to copy files or folders, one of the first things you can try is to re-register the  jscript.dll & vbscipt.dll files. Here are the steps to do that –

1. Open the Command Prompt as shown above.

3. Restart your computer.
