    The Parameter Is Incorrect Copying Files Error


    Sometimes it is necessary to copy files or folders to an external hard drive, a USB flash drive, a pen drive or a SD card from a computer in Windows 10 in some cases. For example, you want to do the unfinished work at home, so you choose to transfer some related files to a USB drive; or you need to copy a program to another computer for an installation. However, when doing such an operation, probably you fail to make a copy and paste to the target hard drive with a specific error. Thereinto, the parameter is incorrect copying files is very common, and Windows prompts you a message saying "error copying file or folder. The parameter is incorrect" or "Cannot copy file: The parameter is incorrect", just like the following screenshots show to you.

Some of the data refused to copy across, throwing up a :Cannot copy file. The Parameter Is Incorrect" error each time. I'm running Windows 10. Also I am trying to copy files via USB - PCI convertor, but the same error happens. Anyone know what's going on? The files aren't corrupted or anything. I can open them and they work. Any suggestion or help?"


    If you also encounter the parameter is incorrect Windows 10 issue, you are likely to be very upset. In this case, the first thing should be to solve this error and then copying files or folders will be finished successfully.

    Why Does the Parameter Is Incorrect Transferring Files Occur


    What Is Parameter


    When getting "the parameter is incorrect" error during the process of copying a file or a folder, you may want to know the main factor causing such an issue. Before I give you reasons, you should know what parameter is. Generally speaking, parameter refers to a special kind of variable, which is used in subroutine. In other words, it means a numerical or other measurable factor forming one of a set that defines a system or sets the conditions of its operation. (–from network definition)

    Why The Parameter Is Incorrect Windows 10


    Here I will introduce you the specific reasons in two cases during copying a file or folder according to different file or folder sizes.

    case 1 Case 1: The File You Copy Is Larger than 4GB

    In some cases, if you copy a large file to a USB flash drive, a SD card or an external hard drive, sometimes you get "parameter is incorrect" message. But you may feel confused that copying small files works fine. Why? This error usually appears due to the limitation of FAT32. While copying a large larger than 4GB to a drive with FAT32 file system, error copying file or folder the parameter is incorrect happens in Windows 10.

    As you know, FAT32 is an old file system which is firstly used in Windows 95, and now it almost can be used in all operating systems. Besides, for some USB flash drives and game consoles, the drive is FAT32 by default. In addition, this file system only supports up to 4GB single file.

    recommend Recommendation:

    Sometimes, you will see an error appears in your computer with "the file xxx is too large for the destination file system" message when copying files or folders. Then this post [Solved] - The File Is Too Large for the Destination File System offers solutions to it.

    the file is too large


    case 2 Case 2: The File You Transfer Is Smaller than 4GB

    In addition, perhaps you ask me: my SD card or USB flash drive is formatted to NTFS and I copy a small file, but the same error is possible to appear in Windows 10. What is the reason? In short, there are three factors.

    1. The target drive you want to copy a file or folder to doesn't have enough disk space.
    If there is not enough free disk space, once the file is a bit large, error copying file or folder cannot copy the parameter is incorrect issue occurs.

    2. Partition table of target drive is corrupted.
    If you don’t safely remove your USB drive, SD card or other devices, possibly virus attacks your device. And then partition table is damaged, which cause incorrect parameter during file copy.

    3. Prepositive USB power supply is insufficient.
    Some compatible PCs may lead to prepositive USB power supply shortage due to the poor quality of power supply, so you fail to copy file with "the parameter is incorrect" message.


    How to Fix Parameter Is Incorrect on SD Card or USB Drive


    Now it is time to take action to fix incorrect parameter error during file copy after learning so much information about this error. Here I will offer you different solutions according to the different factors.

    Case 1: File Is Larger than 4GB


    As you know, the above second part mentioned error copying file or folder the parameter is incorrect issue is caused by 4GB file limit of FAT32. Before you use a SD card, a USB flash drive or an external hard drive, the file system is possible to have been changed to FAT32, but not NTFS. In this case, when moving a file to this partition, the issue happens. Hence, How can you achieve this aim? In my opinion, it is necessary to compress the large file, convert FAT32 to NTFS or reformat it to NTFS from FAT32 in Windows 10.

    solution 1 Solution 1: Compress a Large File


    Once cannot copy the parameter is incorrect message appears, you should split the large file to small files with WinRAR, and each one should be smaller than 4GB or equal to 4GB. For more information, click this post split up a large file with WinRAR. And then try to copy these small files to your partition on the target hard drive without any error message.

    solution 2 Solution 2: Convert FAT32 to NTFS


    In addition, there is another way, that is to convert the drive to NTFS which supports larger than 4GB single file. Generally speaking, there are two ways to do this operation.

    case 1 Run Command Prompt

    In Windows 10, there is a built-in tool that is called Command Prompt which can be used to perform many operations by inputting some specific commands. Here you also can use this tool to change your FAT32 partition to NTFS. Just try as the following guidance shows:

    1. Type "CMD" in the search textbox and then right click this tool to select "Run as administrator".
    2. Then type "convert k: /fs:ntfs". Here k refers to the drive letter of the partition you want to copy a file to.

    convert ntfs

    attention Attention:
    However, sometimes you will fail to convert FAT32 to NTFS with CMD, and you probably receive an error "This drive is dirty and cannot be converted…" In this case, you need to run CHKDSK /F to clear the dirty bit. So this way to do NTFS conversion is not ideal, please refer to a professional tool for help now.

    fail to convert


    case 2 Use MiniTool Partition Wizard

    In order to finish the conversion successfully, a piece of professional and excellent partition and disk software should be necessary. There are many kinds of programs in the market, but in my opinion, MiniTool Partition Wizard is the unexceptionable one. With its basic edition or advanced editions, you can manage your partitions well in Windows 10/8/7/XP/Vista PCs and Windows Server 2000/2003/2008/2012. Here the Free Edition is a good recommendation with powerful functions. This free tool enables you to successfully convert FAT32 to NTFS without data loss in three steps. At first, please download MiniTool Partition Wizard Free Edition and install it to your computer for a free try.



    Guidance is as follows:

    Step 1: Launch this disk manager to its main interface. Then right click on the FAT32 drive you want to copy files to, and select "Convert FAT to NTFS".

    convert fat to ntfs

    Step 2: Then in the pop-up window, click "Start" button to begin file system conversion.

    start

    Step 3: After this operation is completed, click "Close" to go back to main interface, then exit this tool.

    Now the parameter is incorrect copying files problem is solved. Then a successful file copy can be done from PC to an external hard drive, a SD card or a USB drive.

    solution 3 Solution 3: Format Your Drive to NTFS


    In general, there are four ways to format your drive, for example, diskpart tool, Disk Management, Windows Explorer and MiniTool Partition Wizard. Here I will introduce you the last way in detail.

    In the former part, I tell you how to solve cannot copy the parameter is incorrect issue by converting FAT32 to NTFS file system with MiniTool Partition Wizard in Windows 10. Here you also can try this tool to perform drive formatting operation.

    Note: Formatting will lead to data loss if you have saved many data to the partition of your SD card or USB drive. So you should make a backup for important files in advance.


    Step 1: Select the target partition, then click "Format Partition" from "Operations" menu or click "Format" on the above menu.

    format

    Step 2: Next please choose NTFS from file system list. Click "OK" to continue.

    format ntfs

    Step 3: At last, please apply this operation.

    If you haven't backed up some significant data before formatting the drive, don't worry, using MiniTool Power Data Recovery to retrieve hard drive data from formatted partition with "Damaged Partition Recovery" feature.

    recover data

    Case 2: File Is Smaller than 4GB


    solution 1 Solution 1: Replace a Drive


    If cannot copy the parameter is incorrect SD card issue happens, you should consider whether the disk space is enough. Perhaps it is larger than the size of the file you copy, but you still can't copy. In this case, please check whether the file is smaller than 4GB or not. If it is, your drive probably is damaged, so you had better replace a SD card.

    solution 2 Solution 2: Check File System



    If you encounter the parameter is incorrect copying files issue in Windows 10, please try to check and fix the file system error.

    1. In Windows Explorer, right click the target drive and select "Properties".
    2. Then under "Tools" tab, click "Check" button.

    check

    3. If there are some errors, you will enter to the check interface.

    fix error

    4. Then after finishing the repair, click "Optimize" under "Tools" tab.
    5. Next click "Analyze".

    defragment

    6. After finishing the analysis, please start to optimize the defragment.

    Then you need to restart your PC, and try to copy files or folders without "the parameter is incorrect" message.

    solution 3 Solution 3: Connect Your SD Card or USB Drive to Another Computer


    In addition, perhaps cannot copy the parameter is incorrect issue is caused by insufficient USB power supply. In this case, you can try to connect your USB drive or SD card to another computer or to the USB socket behind the computer case.

    solution 4 Solution 4: Format the Drive


    As you know, the USB flash drive, SD card, pen drive or external hard drive is easy to be infected with viruses, which causes incorrect parameter error during copying files or folders and then partition table will be damaged. In this case, if your drive still can be accessed in Windows 10, please copy the important files to a safe location, and then format this drive, just like the way I mentioned in case 1.
