Abdul, one strategy you could follow in order to continue to use separate files is:
1) Encrypt the root program. This must be done as well as possible because it is the weak link.
One way would be with Konxise. Another is with HASP from Aladdin, which has a way to "wrap" an application in such a way that it's tied with a dongle. I am sure there are other ways. Require a new root program from time to time.
2) Keep all other programs encrypted and set up the encryption before calling each one. I use Cryptor (from the same folks as Refox and Konxise) for encryption. It is very effective with hardly any overhead. All you have to do is make a call indicating the file and password and then go about your business with USE, DO FORM xx, DO REPORT xxx or DO xxx. Cryptor intercepts the file reads/writes at the OS level. It's transparent.
Please note that you will need a new fll for each new version of VFP, although I believe there is another way that I can't use because I use an old algorithm. In any case they charge a reasonable amount for the fll.
Recognize that you can't get 100% protection, but at least you can get some.
