Don't worry if you've encountered this error and couldn't copy files or folder to the destination device or hard drive. There is more than one way for you to cope with the problem. Follow to remove 'Error Copying File or Folder' with unspecified error in Windows 10 immediately. Based on the causes listed above, there are the corresponding fixes:

Method 1. Format the Target Partition/Disk to NTFS or exFAT

If you attempt to copy a file larger than 4GB to a partition with the FAT32 file system (you can check the file system of your drive in properties), you will definitely fail. Why? Although the total size of the files that you can copy to a FAT32 drive could be up to 2TB, the size of each individual file cannot exceed 4GB.

If the files that you want to copy is more than 4GB, you can compress the file with WinRAR or ZIP so to get a smaller file. But if this doesn't work or if the destination device offers no access for you to reach with ‘The parameter is incorrect’ message, you can directly convert the target partition or disk to NTFS or exFAT, which can be done by formatting the drive.

Step 1. Open 'This PC'.

Step 2. Find and right-click your target partition. Choose 'Format' in the menu.
