Need deleted drive D: Data files

[MrMath2U]

Hi. By accident I deleted the factory installed files on drive D Data that apparently allows/directs data to be saved on drive D
I have almost filled C drive (10 GB of 118 GB) withe 931 GB of 931 GB remaining on drive D.
Where may I find those files to load into D?  Or do I have to reinstall Win 10 to get them back?

Thanks in advance for any help

If (D) is your hard drive, you do not need any special files or software from HP to save files to it.

You have to explain specifically what files you are talking about. Because at this point, we have no idea what you are talking about.

Hello
The only thing that could already be on this disk, should not be erased like this, is the recovery partition.

so did it look like this ?

 if you have not created the hp recovery kit, you cannot reinstall the computer.
You may be able to use this, check:

Even if the  (D) drive is the Recovery drive, it would not have "files ...  that apparently allows/directs data to be saved on drive D" -- as claimed by the OP; instead, it would have the HP recovery files.

That's why I asked for an explanation of what the OP is talking about.

But @WAWood   that's why I'm asking if that could be what I'm indicating!
I have seen quite a few configurations of this type, and I know very well that there is nothing to install on the Data which automatically manages backups or whatever!

Unless by mistake this has been modified we can have this for example

the only thing that can be in place of origin on a 2 disk is the recovery partition

It is possible that your computer has 2 disk-drives.

The "C:" disk-drive could be a 128 GB SSD (Solid State Device) that is very fast,

while the "D:" disk-drive probably is a 1000 GB "spinning" disk-drive.

Windows is stored on the "C:" disk-drive, and should be very fast to go from "power-off" to "fully loaded & ready to use".

Usually, in such "two-disk" configurations, there is NOTHING preloaded onto the "D:" disk-drive.

Also, usually the "System Recovery" files are stored on a small partition of the "C:" disk-drive. This partition normally is "hidden", so that you cannot access it, and cannot accidentally delete files/folders.

When using such a "dual-disk" setup, it is your responsibility to choose to save new files to the "D:" disk-drive, to avoid filling-up the limited amount of space available on the "C:" disk-drive.

EDIT: reinstalling Windows probably will NOT store any files onto "D:". Reinstalling might even wipe-out your files that you have been storing on "C:".  Ouch!

Read my answer carefully @itsmyname 
I gave an image of a configuration with an m2 SSD and an HDD

"In addition, "System Recovery" files are usually stored on a small partition of the "C:" disk drive. "
The partition is not on the m2 SSD disk, because it is the smallest, it is on the HDD disk !

And as we can see in the second link the recovery partition can very well be used by mistake!
Now what is needed is to have an answer from @MrMath2U , to say if he remembers if it looked like the picture I gave above

For the configuration there is no doubt just read the specs
