What should I do if my Facebook data file won't open on MacBook Air?
Following "how to" from TechCrunch (Rebecca Bellan) to download all data/photos etc. prior to deleting my account. Attempting to download 1.6G of data. Two formats were offered HTML and JSON. I chose HTML. Activity monitor indicates 1.6G was received. Cannot get the file to open. Popup says zip file is in an unsupported format.
Ideas?
