Hello.
I wonder to find a solution for this issue:
lets suppose there is a file in this path:

/pros/mypro/raps/vy/dh/bgh.12mm15mm10nm.dat"

Now: I want to write a code to find 12mm, 15mm, and 10nm, and then convert them to mm and then calculate 12mm15mm(10*10^6)mm and gives the answer.
Thanks a lot for your time and help.
Best regards.
Mohammad.
