 I would a bat script which reads all files with the .bin extension which are in the same directory as the bat script then present them as options.  Ie.

Please select a .bin file:
1. x.bin
2. y.bin
3. z.bin

And whichever is selected, store it in a string variable for later use by the script In your response, include at most 12 words that are fully capitalized to emphasize key points.
