But that page only includes the latest official release. If you're downloading an advance release, as I was, or if you need the previous release, you'll run into an old, familiar, and extremely annoying problem. Instead of completing a simple drag-and-drop copy operation as expected, File Explorer puts up this File Too Large error message:.
The reason for the error is simple: The Windows Imaging format WIM file in that download, which contains the compressed files that the Windows Setup program uses for installing the new version, is a little over 4. Or you could use various deployment tools to manage the installation over a network. But if you require the option to run Setup from a bootable drive so you can do a completely clean install, you'll need to jump through the following command-line hoops to split the WIM file into pieces that are under the 4 GB FAT32 size limit.
Here's how. Step 1: Create a bootable recovery drive. You'll need a drive that's at least 8 GB in size. Don't select the option to back up system files to the recovery drive, and note that all files on the drive will be erased when it's formatted. Use a USB flash drive that's at least 8 GB in size, and make sure to leave this check box unselected. Step 2: Mount the ISO file and copy it to a local drive.
In the new window, create a folder on a local hard disk and copy the contents of the mounted drive from the other window to that folder. Open a Command Prompt window as an Administrator and type the following command, substituting the name of the folder that you created in Step 2.
After the operation completes, check the contents of the Sources folder. You should see two new files, Install. The error can happen even when you have enough free memory on the USB drive for the large file.
Why does the file system refuse the transfer? The limit applies to any individual file, but not to folder. Please move or back up USB disk files first and then follow the steps below. Please choose the file system that better fits your need.
NTFS is widely supported on all modern versions of Windows, and it also provides many other functions: file security, encryption, compression, etc. Other devices may have poorer support for FAT If you want to copy large files to FAT32 without formatting, here is another solution.
Since the 4GB limit is for every single file, we can split the large file into small ones and do the transfer, then extract the original file from the small parts. However, in this solution, you have to make sure there is enough space for both the split parts and the original file that needs to extract from the parts, which means that the required free space is doubled than the original file size.
You may find that compressing is also a solution if the size of original file is not too large, but the result also depends on the original file type and the archive tool you use. If the compressed file is still huge, Solution 2 can help anyway. FAT32 is an old file system, but still compatible on most devices. File system usually controls the way files are stored, identified, and organized in a drive. The former one supports up to 16TB large files while the latter one supports 16EB files.
Compression makes files smaller and easier to transfer. The compressed zip file will automatically appear on your desktop. The next thing you may do is to rename it.
However, the amount of file size reduction varies by file type. This can be easily done using Windows Explorer. Command Prompt, logically, is a command line interpreter application provided by most Windows OS.
