I've read the docs but could not find an answer to my specific question (or didn't understand which one was the answer).
My question context: after I mount the encrypted partition USB drive) on Win10 it is seen as a regular partition and I can move files there. I move files using windows explorer - normal copy-paste in windows.
Actual question: what is happening in the background when I copy-paste a file to the mounted partition on windows? Does Win10 magically know to encrypt it or Vera in the background?
In other words, is the decrypted drive stored in RAM memory for sure? Not on some file on the main hard drive? My guess is yes, but I couldn't find it in the docs.
My worry is the mounted partition is some decrypted file on Win10 main hard drive that is being translated and encrypted to USB drive.
In that case it would mean the decrypted version of all files exists somewhere on the system hard drive. Couldn't find more specific info on this.
The USB drive is bigger than my laptop RAM memory so I just wonder how this exactly works so I can use the decrypted disk and not risk it will be temporarily stored on the main SSD system drive since main SSD is not encrypted it would be no advantage of using Veracrypt in this scenario.
