Amiga style dynamic ramdisk for Windows?

[Jon P. Inghram]

It seems to be a lost or possibly alien technology, oh well...

[CHHAS]

You mean the recoverable ramdisk that would survive a warm boot ?

[Indiana]

No. He means a dynamically sized RAM-disk - that means the RAM-disk adapts its size dynamically to match the size of the content you put in there.

Why do you need a RAMdisk?

[Jon P. Inghram]

It's handy when decompressing software that you only need to use for a moment, and other similar things that don't need to be stored on real media.

I have also been hunting after something like this and what I found was a sort of general stupidity

"but what for? windows cache will work much better than that anyway"

[Rakido]

something like this

That's a fixed one too. AmigaDOS understands that zero freespace on the ramdisk isn't a bad thing, not sure if Windows is even able to do that, oh well.

[Rakido]

found some more, but it looks as all of them have fixed sizes

Ramdisks make excellent temp directories when compiling large projects.

That MS one worked quite well, but was a bit inflexible for me, If I were not so lazy I would try and modify it.

[Gurm]

The problem is that it would involve patching the entire OS.

Disks with no free space are bad in the MS paradigm.

You can't add a file to a disk with no free space - it generates errors all over the place. This is why what you're looking for doesn't exist.

Returning a max size for the space required.
And allocating from the heap as needed should work.

[Gurm]

Yeah but I'm willing to bet you a large sum of money the calling routine doesn't tell it how much space it wants it to have. It just says "how much space is there?" the RAMDisk says "none", so no file copy.

Now, if you had the RAMDisk return "a gajillion bytes", you'd get even more errors. Basically you'd have to have it pick some facetiously large number based on the amount of available memory... and it'd get real ugly real fast.

And current HDDs have a STR in the range of ~1990 computers FSB.

AR Ram is pretty good. This is going to work wonders for my sound editing which insists on using hard drive space no matter how much ram I have. Then again it did come for no extra cost with my sound card.
