thanks.ISO should have better compatibility and performance than games in folder format. Also Iso can be played from exFAT or NTFS.
If the game has hundreds or thousands of files, it's a great candidate to be converted to ISO.
If the game has a few large files, you won't notice a big difference in performance. I prefer to keep these games in folder format to save the conversion time.
which method you recommend for convert folder to iso? multiman ? or a special windows tool?
