    Hello experts!
    The background story:
    I was working on something yesterday night and got so enthusiastic about my work that I forgot to save regularly :(
    At some point the application I was using (PDF annotator) just hung. Just stopped responding, the sand-clock appeared, I could otherwise use my comp normally, I could even minimize - maximize my PDF annotator but couldn;t do anything. I went to TaskManager, stopped or unnecessary processes etc but didn;t help.
    I put my comp on standby, woke it up, didn't help. I put it to hibernation - didn't help. So I booted into linux and copied the hibernation file (over 1GB in size, is that normal?) to another disk in case it would get deleted upon reboot.

    Now my question is, is it possible to somehow read the data from the hibernation file? Because I assume that all the unsaved data should be there, or not?

    Thanks for your help!

    I'm guessing at best, the hibernation file would restore you to where you were - locked up....

    Not sure if I asked the question clearly...I don't want to use the hibernation file during waking up - that is working well :) and you are right steve, it takes me where I was, locked up.
    What I have in mind is if there is a way to open the file and actually read the data - OK I can open it in a text editor but it is not readible,at least not for me. Is it possible to decipher it somehow to extract the actual data? And would it actually contain the unsaved data from opened documents..? :confused:

    The answer is no, it's one of those "You can't get there from here" situations. Cache and data files are not directly accessible nor can they be copied elsewhere for use without becoming corrupt. I'm afraid you're out of luck there.

    The info stored within them is in data bit by sector and not in any software format, so if you could access then, you'd have no way to associate that data with what it meant to some software that it was referencing at the time. It's a dynamic situation and has only one window of opportunity.

    You put the pc into hibernation After PDF annotator got hung...Odds are your info was gone with the wind at the point where it hung...

    OK thanks for the explanation. But I am sad :mad:
    I guess it's the fault of the software manufacturer that their software doesn't create something like eg Word does, these ~blabla570925.tmp files.

    The software will produce temp files - otherwise it would not remember your input - the question is where are they kept and are they accessible? I would guess the location to be .....

    C:\Documents and Settings\Username\Local Settings\Temp\xxx.tmp

    or C:\Windows\Temp or in the program folder itself.

    FYI - For the production of .pdf files I work in Word 2003 with autosave enabled and then use pfdFactory to 'print' to a .pdf file. I think Word 2007 will save natively as .pdf.
