ISO File Systems

Hey guys, this is Matt. Kids on the one with the video on ISO.

So, as you may know, when you, um, for instance, create a copy of a CD or when you earn a CD or anything like that, you might make an ISO of a CD.

And you might know that ISOs seem to act a lot like DMGs, but what you may not know, or you may know, is that ISOs are not the same as DMGs because they have a limit in size. They've eliminated a bunch of other things and they have their own special kind of file system.

So you also may or may not know the different hard drives, such as on the Mac, have different file system formats. On a Windows computer, it's normally NTFS or, um, FAT32 or, as you may know, MS-DOS.

And MS-DOS or FAT32, whichever one you want to call it, has a file size limit of four gigabytes. That's very frustrating, so people use NTFS in Windows normally.

Now, on a Mac, your file system is formatted as HFS Plus, which is very nice because file names can be up to 255 characters long. So it's pretty nice.

Um, but you may or may not have wondered, what format is a CD? A CD is ISO format. ISO is the special thing for CD or DVD; some DVDs can do it too.

And ISOs have a lot of limits that, um, the thing that HFS Plus doesn't normally. DMGs are HFS Plus or MS-DOS if you like doing that, but ISOs have limits like, um, originally, you could only have 10 to 8 levels of folders.

And, um, it was also originally said that there could only be one dot in a file name; that got changed though, um, because of Unix systems and dot files and stuff.

But ISO is another format for CDs, and that's what a CD normally is. Now, a music CD isn't normally added.

So, anyway, I hope this, um, vaguely, um, explained to you what ISO file systems are. Um, so in the description, I'll have a link to ISO's Wikipedia page, um, and I'll, um, just, yeah.

So, um, anyway, thanks for watching that kitchen one. That's just a little insight about ISO file systems.

So, anyway, subscribe and goodbye.
