Hello my friend!
I finished my first project that it has 30 driving tests for drive license. But i have a problem.
First i want to inform how app works. When you install and first first first run, programm copies all (505) images of road sighns at DirDefaultExternal. At normal phones with 1Ghz processor there is no problem. I tested yesterday at HTC Wildfire S (600Mhz and 512 RAM) and it took too much time to copy all these files. About 2 secs before copy ends, it throws me a message that my app does not response. If you "wait" and not "forse close" after 2 secs it ends the copy and programm working like a charm. I want to tell you again that my problem occurs only at "low" phones.
Now my question, do you have any better idea how to copy all these 505 images at DirDefaultExternal?? (see my code down)

Try putting a DoEvents in between each group copy.
