Recently, I needed to format a thumb drive to FAT32 in Windows 10 (adding the BleemSync hack to the Sony PlayStation Classic). I could swear the last time I had to do this, the option was there. Today the only options were exFAT and NTFS. Ugh. Windows! Well, I found a nice free tool that allows you to perform this task: Ridgecrop Consultant’s FAT32 utility. Once you visit their site, click on the picture to download the utility.
There’s another option. You can type ‘cmd’ where it says “Type here to search” from the Windows 10 menu. Once the command terminal is open, type (replacing “X” with the drive letter):
Format /FS:FAT32 X:
This method will likely take hours to format the drive.
