What is the size of that file? If you are getting that message, 16GB may not be enough to be able to load and edit the file. Note that a 17 hour file will consume a lot of your system resources, so you will need a powerful computer to be able to process it. In this case, I recommend you free up space on your hard drive to see if it helps. Also, if the file is stored locally on your computer, you can move it to an external hard drive and try to load it from there
