- Hello! Tried using Irisman to get my iso file from USB, but for some reason when I'm done transfering the file to PS3ISO folder, it shows the game with the generic "blu-ray Disc" image and opening it doesn't do anything. Is my iso corrupted or am I missing something? Also for some reason deleting that 20gb iso file or moving to a different ps3 folder(after already transferring from the USB) using Filezilla/Irisman takes a few seconds instead of 10-15 minutes like with the other files that size, so I thought that iso itself might not actually be 20gb like I thought, and yet transferring it from USB to PS3 took quite long.
