Make sure to delete the file in-between tests. Without code its hard to guess.

Like BN2 says, the file has to be deleted. Open to write creates a file, then loads data to it. If there is a file already with the name you're trying to use, then it will return an error. Therefore this code may cause problems

+ Code Snippet

open to write 1,"filedata.txt"

where this code would work fine

+ Code Snippet

if file exist("filedata.txt")
  delete file "filedata.txt"
endif
open to write 1,"filedata.txt"

However it is worth remembering that deleting files haphazardly may cause problems. Therefore, if the file is required for your game (for example a high score table) it may be worthwhile loading all the data into your program using open to read, then storing it, before you delete the original file. That way, important data won't be lost.

@TDK:

Your tutorial on file access is simply brilliant. It helped me out a lot when I started learning how to create game files. Now you should make a tutorial on how to make a basic level editor!
