Spanning folder across two disks

I use a program called Hitfilm Express and the user can specify one folder to use for "proxies" which should ideally be a fast disk but I'm running out of space on my data SSD so I was wondering whether it's possible using symbolic links or some such voodoo to have a folder span my SSD and an HDD RAID 0 I also have.

I'm using Windows 10.
 
Solution


No, but looking at the Hitfilm properties for where the Proxy is...it gives an option for a single folder.
A symlink does not span across folders and drives.
Symlink simply fakes out the OS into thinking a particular folder or file is on Drive 1, when in...

I don't think it would bring the SSD down to the performance of the HDD. The performance would depend on where the file was. If the file was on the SSD there would be SSD performance and if the file was on the HDD there would be HDD performance.

If there's enough space on the SSD, then why the spanning or symlink?

Why does there need to be sufficient space on the SSD for all files for what I said to be true?

You want to use some space on the SSD for the Hitfilm proxy.
But it seems your SSD is getting slim on free space, hence the initial question about spanning.
Correct?

But then..."The performance would depend on where the file was. If the while was on the SSD there would be SSD performance"
If there is sufficient space on the SSD, then why the need for the spanning?

Hitfilm gives you a single folder location for the Proxy. Similarly, the cache and DB cache.
I don't believe you can cause that to span across two drives or folders.

But it's pretty easy to change back and forth.

It's not complicated. Some proxy files would be on the SSD as they are currently and they'd be accessed at full speed. Those files written to the HDD would be accessed at a slower speed. The files accessed on the SSD would not be accessed at a slower speed just because there's also files on the HDD. There may well be no way to do this in Windows but that doesn't mean that if there was, the files would all be accessed at HDD speeds. I suspect that you're being disingenuous.

Symlink simply fakes out the OS into thinking a particular folder or file is on Drive 1, when in reality it lives on Drive 2.

I can't see any functionality that would cause it to use 2 different folders.

So the solution doesn't involve symlinks but I didn't say that the solution had to involve symlinks. There could be some other way using some other kind of ***link or a sym**** or whatever. If I knew what the solution was or what search terms to use I wouldn't have posted. Unfortunately "file system concepts and tools I haven't heard of" doesn't yield quality Google results and symlinks are the outside border of my knowledge on files system concepts and tools.
