I have program with data accessed by MySQL. In my assume, I copy program and
its data files to my friends, and they run program with pleased faces. And
now, the first friend wants to delete all program related data files and
copy program related data files from second friend(or he can also get any
program formatted data files) and save them into data folder. My problem:
the first friend can run program with only my data files; he can get any
data files from anywhere and save them into data folder, but program won't
be allowed to read these data. Does everyone have some good ideads?

In general, it is considered a good idea to provide necessary information:

1) Which version of MySQL,
2) exact comnmand(s) used,
3) exact error message text,
4) which operating system.

From you description, I strongly suppose it is a permission problem,
probably the files copied among the "friends" end up with a different
ownership or access rights than those of the original installation.
