Hello,

The Open file and Create file macros expect a 8.3 type filename.

For example test.txt would be entered like this.

"test.txt"

But a longer filename such as BensTestFile.txt would need to be entered like this.

"BensTe~1.txt"

Because of this is it advised to use a filename length of 8 characters or less and a file type of 3 characters.

If you must use long file names then there is some more info here on short path names: http://superuser.com/questions/348079/h ... ctory-file
