What is a extended filesystem?

[RuffLiner5579]

What is a extended filesystem from what i hear it's used to install applications outside the original filesystem is that true?

[khafa]

hi,



the extended filesystems i know are
ext fs

maybe you are talking about something different.

The only other info I might have for you is this. It's kind like what khafa posted, though.

What is a extended filesystem from what i hear it's used to install applications outside the original filesystem is that true?

That phrase doesn't make any sense to me.

There's two things I can think of, though:

1.- extended filesystem, which is actually a filesystem, just like fat or ntfs, but for linux. There are lots of different filesystems. Just like there are lots of different OSes out there. There are actually three revisions of the so called "extended filesystem": ext, ext2 and ext3. Additionally, ext4 is in the work, and will hopefully soon arrive. Those filesystems (well, except for the first revision which as far as I know was abandoned long ago) are widely used under linux. Ext2/3 is considered to be the native filesystem for linux because ext was the first filesystem designed exclusively, unlike the rest which are just ports, or have been designed for multiple platform support) for linux, just like fat and ntfs are native filesystems for windows.

2.- extended partition, is an special type of partition that can hold logical drives into it. This was invented to overcome a limitation, since pc's couldn't deal with more than 4 partitions. Inside an extended partitions you can create more logical drives, thus, extending the limit.

If you don't understand a word, try to describe what do you want to do on a simple but concrete way if it's possible. Hopefully, we can figure a way to help you.

I use a Cd Distro that has only a small space to install Applications to without a way to install it to a HD so I need to be able to install things to some other place then the disc.
Any help?

Some live CD's have an option or utility to save changes to a small file on your HD for later retrieval. I know with Damn Small you can save those apps on a USB stick. You can also do a Frugal install for it to save those changes. Info can be found on the DSL wiki page. Also, Puppy linux gives you the option to save changes every time you reboot. Is this something like what you're looking for?

[RuffLiner5579]

Actually I knew that I could save things to alternative directories but I really need to set up something that will allow me to install applications outside the OS.
I have 30mb on the CD and a 100GB HD to install stuff to if possible.

[jayd512]

I'm a bit confused here... You mention not being able to install to a hard drive, but are looking for a way to install applications to one? Without installing the OS? If that's the case, then saving to an alternate directory would seem the wisest course. If I'm not understanding you properly, can you try to explain it a little differently?

[RuffLiner5579]

I'm a bit confused here... You mention not being able to install to a hard drive,

Ya I can't install the OS to the drive.

but are looking for a way to install applications to one? Without installing the OS?

Ya thats it.

If that's the case, then saving to an alternate directory would seem the wisest course.

An alternate directory I don't quite get how because that would imply that you can compile applications without any folders/files on the drive or are you trying to say that we could compile a new directory of folders/files first to that drive that then could be installed to by applications?

[jayd512]

Well... I've never done it with any OS but Damn Small, but a frugal install is an option the you would have with that OS. It sets up a folder ON the HD... very small memory footprint. Without installing the actual OS, you can save apps and updates for later retrieval and use. Not sure if you saw the link earlier: Persistence - DSL Wiki

That may be of some use.
