Hello,
You should be able to access a text file on your PDA if you use the correct file path and file name from within your program. From the Palm, this is usually just the file name (like "textfile.txt") since there is no real directory structure. So, if you create a string constant, use the filename, convert it to a path, and use that for your File I/O VIs, you should be able to access the file. (If you type the filename into a path constant, it will automatically add the "C:\", which is the reason for the conversion.)
Have you tried this? Do you get any errors? What goes wrong? If you'd like, I can try your program here to see if I can reproduce the problem and offer any further help.
