If you try to move large files in Windows 10, the process may cause an error. Don’t worry, it’s easy to fix error 0x800700DF.

Windows may display error 0x800700DF: “The file size exceeds the allowed limit and cannot be saved” while copying a file locally, or while copying a file to an external storage device or its upload to SharePoint.

If you’ve ever encountered this problem, you know how frustrating it is to have enough free disk space, but Windows tells you that the file size is over the allowed limit. This article explains how to correct this error.

Set Your File System to NTFS:

If your file system is currently set to FAT32, will have no problem transferring files as long as their size does not exceed 4 GB. However, when uploading larger files, you will encounter error 0x800700DF. Instead of splitting your files, you can set your file system to NTFS, which will allow you to copy files up to 16TB in size.

Note : Changing the file system for any of your computer‘s partitions will delete the data you have stored there. You must therefore create a backup before making this change.

Follow these steps to change your file system settings:

Launch File Explorer ( Windows + E ) and navigate to the problem partition or storage device.

Right-click on it and select Format .

Set File System to NTFS .

For Allocation unit size , select Default allocation size .

Enter a name under the Volume name heading .

Uncheck the Quick Format option .

Click Start .

After the process is complete, restart your computer and check if you are still getting the file size error when copying a large file.

Modify a Registry key

If you get the error “the file size exceeds the allowed limit and cannot be saved” when transferring a file on your Windows computer, you need to look at your system settings. The Registry Editor stores your system and application settings.

Changing one of the registry keys should resolve the file transfer issue:

Press Windows + R to bring up the Run dialog box .

Type regedit and click OK .

In the registry editor window, use the left menu to navigate to:

HKEY_LOCAL_MACHINE > System > CurrentControlSet > Services > WebClient > Parameters

In the right pane, open FileSizeLimitinBytes .

Set Value Data to 40000000 .

Set the Base to Decimal .

Click OK .

Close the registry editor and restart your computer.

Activate the Web Client Service

If you encounter this file size error when using SharePoint or a similar application that uses WebDAV, you should take a look at Windows Services.

In the Start menu search bar , search for services and select Run as administrator .

Open WebClient and check if the Service Status line says Running . doubt not, click Start .

If the service is already running, click Stop > Start to restart it.

If you still can’t upload files to SharePoint after enabling the Web Client service, see SharePoint upload settings. Make sure the upload limit is larger than the size of the file you want to upload.

Conclusion

With the error “the file size exceeds the allowed limit and cannot be saved”, you may lose your data while trying to transfer it. Although you can recover your data with Windows built-in tools, it doesn’t always work as expected.
