WBFS for Windows

This is a guide that explains how to partition and format your drive to WBFS so you can use it with any USB loader.

This guide should work on Windows 2000, XP, Vista, & 7. It might work on lower versions too.

WBFS is a file system that enables you to store ISO images onto a hard drive, without the empty data that is added to make every ISO image equal 4.37GB or 7.45GB.

So each game will have a different size ranging from 10MB to 7100MB.

Using the WBFS filesystem is no longer recommended. The earliest versions of USB loaders could not use anything other than WBFS, but nowdays you can use any FAT32 or NTFS formatted drive.

Required

• A computer with the USB device inserted.

Links

• EASEUS Partition Manger 3.0 Home: http://www.easeus-software.com/download/epm.zip

Result

• Create a WBFS partition on your hard drive.

Guide

1. Download EASEUS Partition Master and extract the contents of epm.zip.

Run EMPSetup.exe to install EASEUS Partition Master and run the program.

Here you will see any Hard Drives connected to your computer.

This program does NOT detect removable storage.

Disk 1 should be your main drive which is mostly likely drive C:/

Disk 2 should be your hard drive if no other drives are connected.

What your trying to accomplish with this program is to divide your drive to whatever size partitions you want so you can be left with an unallocated space you can then format to WBFS.

2. Right click the drive you want to partition and choose Resize/Move.

You should now see a Resize/Move Partition window pop up.

The partition size is the whole size of your drive in Megabytes [MB].

Here you must use the arrows to decide how big your WBFS drive will be.

Notice how when you move the arrows around, the Unallocated Space After box changes. This will be the size of you WBFS drive.

You can either use the whole drive as WBFS but it is recommend leave at least 1gb of a fat32 partition.

You can use this GB to MB tool to find out how much MB you should set it your Unallocated Space After to.

3. Choose the amount of your Unallocated Space After space and press OK.

4. You should now see your drive as a smaller size and a new Unallocated * drive underneath it. When you are satisfied with the size of your soon to be WBFS drive, press apply down on the bottom left. The confirm with Yes.

This should be quick or take a while, depending on your drive and computer and whatnot.

5. Go to My Computer, right-click and select manage.

6. Click on Disk Management towards the bottom left.

Here you should see your connected disk drives again, with the unallocated space there.

7. Right Click the unallocated space and choose new partition

8) Click next and choose primary partition

9) Leave the partition size at the maximum.

10) Choose whatever letter drive you want to assign your WBFS device to. I always choose W when I can but any letter is fine.

11) Choose Do not Format this Partition then click on finish.

After this your drive should be ready to go with any WBFS manager out there that has a built in WBFS formatter. Just choose your letter drive you created in Step 10.
