FAT32 isn't an application, it is a file system that is used to for storing files on storage devices, like hard drives, memory sticks, etc.
There are other file systems, such as HFS+ (Hierarchical File System plus) that is used by Mac OS X and NTFS (New Technology File System) that is used by Windows.
FAT32 (File Allocation Table) is a file system that Mac, Windows, and Linux can read from and write to.
To format your external drive to be FAT32...
From Mac OS X:-
- Plug in your drive,
- Open up Disk Utility
- Select your external drive from the list on the left
- Click on the erase tab,
- From the Format drop down list, select MS-DOS (FAT)
- Click Erase...
From Windows:-
- Plug in your drive,
- Open My Computer,
- Right click on your drive and click Format...
- Select FAT32 from the list of file systems,
- Make sure Quick Format is checked,
- Click Start
Always remember that formating a disk will erase all of the data that has been stored on it. So make sure that you have everything that you want to keep backed up.
