HT4500 how do I transfer files I backed up with Time Machine in an external disk to a PC?

Question

I back up using Time Machine in an external hard drive in my Mac Air. I need to open those files in a PC, but I can't open the files. How do I open them from a PC?

Answer 1

TimeMachine first saves a complete state of your Mac's boot drive, then it saves incremental updates consisting of changes and uses placeholders (file names with no content) for those files that didn't change between states.
Now it will do this until there isn't enough room on the drive and then it starts deleting older states.
So it does it like this so there isn't any duplicated files wasting precious drive space.
Now what does that have to do with your problem? Well there is no TimeMachine software for PC's that can decode this mess and get to the files you want.
However if you understand a bit more details about it, then you can perhaps recover your files.
TimeMachine uses the same drive formatting as on a Mac, OS X Extended Journaled otherwise known as HFS+ or JHFS, and Windows PC's can't read that format natively.
However there is third party software called MacDrive which you install into Windows that can read that drive format.
The next trick, if it works, is to look a the TimeMachine folders and find your data, but have to recall when it was created as to go back into the correct folder or else you will find the empty placeholder with the same name and no data.
Next if you can recover files, is being able to open those files in a compatible PC program, which a lot of Apple software and OS X based software might not have PC versions.
Neutral formats like Mp3, jpg, .mov, .doc, .txt and so forth can be opened on other platforms using other programs, however the more platform or proprietary the files are in, then the harder it is to find a PC version that will work.
What you can do is to use the TimeMachine drive on a temporary Mac (OSX version has to be same or later than on the TM one) and restore the users accounts/software to that Mac and then go about retrieving data or simplifying the data or transporting it into more neutral/cross platform formats.
LibreOffice is excellent for this as it's the only Office suite that's cross platform with Linux, Windows and OS X, plus works with OfficeMac/Office Win files. So pasting into that will preserve a lot of formatting etc, that will be lost if you just pasted into txt format.
I've been aiming to create a transition to Windows User Tip, perhaps one day I will.
