Plug into a Windows computer a flash drive containing the full MarpX Privacy set of files, preferably a fairly recent set. Most computers have two or more USB ports. Plug in a second flash drive that is empty or nearly empty. This flash drive will receive the copy. If there isn't a second drive, you may need to find a place on the PC's hard drive onto which you can temporarily copy the files.
Usually when a flash drive is plugged in, a message like this pops up:
On the pop-up select "Open folder to view files." If there is no pop-up, click on the Windows Explorer icon (in Windows 10, the File Explorer icon), navigate to the flash drive, and highlight the MarpX directory.
The list from the MarpX Privacy flash drive will include lines like these:
The list from the empty flash drive will look like this:
Highlight the MarpX directory in the first drive. Copy its entire contents by simply holding down the CTRL key and press the letter 'C' once. Then click anywhere within the empty list, hold down the CTRL key and press the letter 'V' to paste the entire MarpX directory with all its files. The entire file set will be copied from the one flash drive to the other.
Very important: Copy only the MarpX directory with its contents. Do not even think of copying the DoNotShareLog directory, because that would risk other people learning the keys that you have used in the past. That would NOT be privacy. Don't do it.
You now have another MarpX Privacy program, fully installed on the second flash drive. It will work right away at Level One with no charge. Make as many copies as you wish.
