How to transfer a large file on to fat32 external HDD

Hi guys

I have recently jailbroken my ps3 for the first time and wondered how I transfer a large game backup or movie file from my PC to an external HDD?

I then plan to plug the HDD into the PS3 then run my backups...

Any help would be appreciated

Thanks

plug the external drive into your pc.

Create these folders to the root of the drive, then transfer to the folder needed
