In several topics I read about people duplicating video files to support multiple versions of the same script. The obvious downside here is the additional disk space used.
I wanted to share a better way which is just as fast, by making symlinks (a reference to a file that behaves as a copy of said file). You can create them from a terminal window, but to make it easy there is the following program:
Windows Option
Note: Only works on NTFS filesystems.
After installing you can rightclick + dragdrop a file and it creates a symlink of the file.
You can rename the symlink to your alternative script, with the end result being as follows: Note the Symlink takes up no space. All video players will treat the .symlink as if it is the linked MP4 file.
MAC OS option:
LINUX
ln -s file.mp4 file.easy.mp4
