I'm struggling with the term ramdisk in connection with Redshift 3D and textures; I haven't heard it in nearly two decades. It was a virtual disc on a Mac based on a defined Volume in RAM back then. The Manual of Redshift 3D does not provide this term at all. So, I might miss something here.

I would surely like to help, but I'm unsure what to do with this short text.
You gave more information elsewhere, as far as my Google search tells me.

I try to not answer from memory, as things might have changed, so I love to explore it carefully, as you can see below: (Sorry for the longer text)
.

I have recreated the names as you had it "elsewhere" posted, if that is the same you: I would not place periods nor only sequence numbers as identifiers in otherwise unrelated files. In short, that is nothing where I have any experience with.

Anyway, I placed those in a folder, connected a few via a Texture Node, and applied them to different objects. After that, I renamed the folder holding the Files and placed that folder into a new folder. (Which should be sufficient chaos for any system.)

I went to the Main Menu>Redshift> RS Asset Manager. Used the "Select Missing Files"

Then I selected only the SSD icon, and all files from that drive were instantly re-connected

.
I did this again: I created a new folder and then placed any content in it. This time I checked the Main Menu> Window> Project Asset Manager.

Also, here, Select missing items, the Relink, and click only on the SDD holding the items. All instantly connected.

.
OK, one more: Using the Preferences> Files> File Assets: Path

Here, I can click them on or off, and the Files are connected (on) and then not (off)

I hope that helps, as I surely know how annoying any work is that does not increase the quality of a project.

Have a nice Sunday and my best wishes for the project.
