The FileOpen Function of AutoIt is used in conjunction with other functions, such as the FileRead or FileWrite functions.
This function opens a file for reading or writing.
The file handle must be closed with the FileClose Function.
Returns -1 on failure, and returns a file handle on success.
Parameters
Filename and Path
The path and filename for the file to be opened.
Mode Optional
The mode can be a combination of the following:
0 Read mode (default)
1 Write mode (append to end of file)
2 Write mode (erase previous contents. I.e. Overwrites a file)
8 Creates a directory structure if it does not exist.
16 Force binary mode

AutoIt FileOpen Example
In this example a mode value of 10 is used, (2+8) – erases previous content and creates directory.
$file = FileOpen("test.txt", 10)
FileWrite($file, "Line1")
FileWrite($file, "Still Line1" & @CRLF) ; The CRLF at the end is a line break
FileWrite($file, "Line2")
FileClose($file)
