Hope I’m not butting in… Just wanted to offer a comment…
As AmberV discussed above, Scrivener projects are not just a single file.
Each project is a folder, whose name ends in .scriv
Example: myproject.scriv
Each project’s folder contains numerous files and folders, all of which you will need. If you look inside the project’s .scriv folder, at the highest level inside you’ll see a .scrivx file (typically project.scrivx), plus folders named Files, Settings and Snapshots. They in turn contain additional folders and files.
To repeat, for each project, you need the whole thing, the .scriv folder and everything that was in it.
So when the computer tech is searching, they need to locate the .scriv folders, not just the .scrivx file. They can do this by either searching for folders (directories) having .scriv on the end of their names or by searching for .scrivx files, then looking a level up where each is found, to determine the .scriv folders they are in. They then need to copy the entire .scriv folder(s).
Hopefully that’s what they’ve done and provided you.
Moving on…
You mention they gave you a disk with the hopefully recovered files on it. If that’s a DVD or other read-only media, you’ll need to copy the entire project folders onto a writeable drive, probably your main drive that Windows launches from, your desktop and documents reside on, etc. so that Scrivener can open the project. Typically, that is the C: drive. Scrivener needs the write access capability that provides, even if all you are attempting to do is just open the project.
Hope that helps.
Hope things are well with you and yours.
