Hi, My 11" MBA says that I have close to 20 GB in video files. I would be more than happy to transfer those files to an external hard drive. It would be amazing to be able to free up some space of the hard drive of the 11" MBA. For that, I would just need to recognize which files are video files. Would you please tell me which ending do they have or any other way to recognize them? Thank you, kind regards, igmolinav : ) !!!
