Iso Is Too Big Wintoolkit

I have an Iso file of windows 8.1 pro with December '14 updates. The problem is the file is too big to be burned on a normal 4.7GB DVD , its around 4.8. Now is it possible to remove a few updates so that i can make a bootable windows DVD.

Or is there any other alternative so that i can store this on DVD.

I tried compressing it to .uif and .7z format but even though the size reduces the numerous ripping softwares i tried using said this file was too big even though the windows properties of this compressed file says its less than 4.7 gb

I keep my windows 7 x64 iso up to date every month, adding the new. Look at how every image is about 6GB bigger on the updated image. Every time, but that takes WAY TOO MUCH TIME, about 6 hrs, because it has to. The file “myfile” is too large for the destination file system. So I wondered to myself what could possibly cause this issue. My external hard drive had tons of free space, so why would I not be able to copy this file over?

As you already noticed: Compression is not going to work.
You can compress the ISO file however you want when it sits on your harddisk, but the data is always written UNCOMPRESSED to the DVD. The DVD format doesn't support compression on the DVD in this way.

Modifying a pre-build ISO to take out some updates is possible but it is an arcane art.
Extremely complicated and you will need to have a very good understanding of how slipstreaming works.

Rolling your own ISO starting from a base Windows ISO and adding only the desired patches (and possibly some drivers) is MUCH easier and you can control the size of the resulting ISO with a lot less hassle.

Obviously you can burn to a dual-layer DVD. This will give you an effective capacity of 8.5 GB.

But:
Have you considered to make a bootable USB stick instead ? It is a lot faster to install Windows from USB.
A 8 GB USB stick costs about the same money as a couple of dual-layer DVDs and the USB can be re-used for something else after use.
(Also bear in mind that DVD drives are not really standard anymore in new computers. But they all have USB ports and can boot from a USB device.)

You can download ISO without updates from MSDN website where the size will be equal to 2GB of size and after installation of the OS you can install the upgrades.

You can use nlite or rt se7ven. These programs allows you to customize windows os. Here you can remove unwanted drivers(There will be plenty of drivers which your device dont have. Windows by default put all drivers for ease. Be aware of not removing controller device). Remove all the language packs, Feature you dont want like internet explorer, wmc, media feature, wall papers,softwares.Expert peoples are able to make a 500mb win 7 os from these easy to use tools within an our.

If you buy a dual layer DVD, they are about twice as large and should be writeable by a regular DVD burner. Would that be big enough?

Imagine that you’ve bought the USB flash disk with capacity of 16 GB or external hard disk. Sooner or later you’ll need to transfer files larger than 4 GB, whether it comes to ISO files, backup copies of your operating system, movies, personal video files or other; so when this situation happens, while copying or moving your large files to USB flash disk, the following error may occur: The file is too large for the destination file system. In this article we’ll discuss ways to prepare an USB flash disk or external hard disk and seamlessly transfer large files (greater than 4 GB) to your USB flash disk.

Let’s simulate this situation: I inserted my Transcend USB Flash with 16 GB in my computer, with the Windows 8.1 operating system and the operating system assigned H: drive letter to my USB disk. I double clicked it and put a file in this disk (Creative Blog logo):

Windows 10 Iso File Too Large For Usb

On my Desktop, in Transcend folder I have really large file, over 8GB (you can see both Transcend folder and the root folder of my USB disk displayed on the screenshot below), so I dragged that Fil.iso file and dropped it to my USB disk:

… but the file is too large:

The first thing you need to check is the file system of your USB disk, whether it is FAT32, to be precise. Default file system format for my Transcend flash device is FAT32, which lacks support for files larger than 4 GB. To be sure what file system you have, right click on your USB flash disk (or hard disk) and select Properties:

Windows

There are two ways to fix this:

  • Formatting your USB disk to NTFS file system,
  • Converting FAT32 file system to NTFS without data loss.

How to format USB disk to NTFS file system and avoid file is too large error

If you choose this way it’s mandatory to copy all your files from the USB disk to your PC, because all files on your disk will be deleted. After the format to NTFS is finished, you can copy that files back from PC to USB disk. Follow this procedure to format your disk to NTFS file system: right click on desired disk and select Format:

Select NTFS, Volume label (this is good practice; my label is CREATIVBLOG) is optional and tick Quick Format option (quick format is quite sufficient). When the format finishes, try to transfer large files to your USB disk.

How to convert FAT32 to NTFS without formatting or losing data on USB disk

Yes, this is possible, too: we’ll use convert command in the command prompt to avoid disk formatting and unnecessary copying files to your computer; this is a simple and time effective way to convert FAT32 to NTFS file system.

Open your command prompt; I always start it via Run dialog box – hold this key combination: Win key + R to open Run dialog box:

Enter cmd and confirm with Enter to open the Command Prompt. Enter the convert command in Command Prompt to start the FAT32 to NTFS conversion. It’s important to double check what letter is assigned to your disk (letter H is assigned to my Transcend disk, which I marked with the red rectangle):

Enter the command as follows: Convert H: /FS:NTFS and press Enter. The conversion process will start:

After several minutes the conversion process will finish, and you can now try copying large files to your disk:

This command is supported on Windows XP operating system and above.
