A friend of ours had her wedding photos and videos uploaded to dropbox via their photographer. however this came after arguements with him about the stuff not being ready and now he has stopped replying. we have the folder on dropbox but they are very large .mov files. largest is 147GB. the files wont open on anything as it says the server is down or the file is not supported. i'm on windows but have downloaded converters and tried to convert them but no luck some have audio but no picture. My friend had downloaded onto a hard drive but says the file is encrypted. any help greatly appreciated.
