public static boolean couldWrite(java.io.File file)

Attempts to determine if the application might be able to write to the given file, which may or may not already exists. If the file exists, it just calls the canWrite() method on it. Otherwise, it looks at its parent directory to see if that exists and checks to see if that directory can be written to.

Parameters:

file - The file (which may or may not already exist) to see if it can be written to.

Returns:

True if it should be possible to write to the given file.
