How can forensic analysis prove that files stored in a virtual disk are never written to the hard drive?

After creating a virtual disk mounted to a folder (e.g., `C:\Windows\Temp\test`) and writing a test file, forensic tools like WinHex can be used to open the physical disk and navigate to that folder. The test file will be absent because it resides only in memory. This confirms that the RAM disk completely bypasses the hard drive, making traditional file recovery impossible, as discussed in the article's forensic analysis section.
