First, stop using the PC now. The more you use it, the more likely any useful information will be overwritten.
Second, find someone with computer expertise and take your PC to them and ask for their help. Give your university IT department a call and ask for help. It may even be worthwhile them cloning your disk - taking an
exact copy of it including all the deleted files, and working on the cloned disk. The problem is that every time you power the PC on, or do any work, you run the risk of overwriting stuff from the broken file. Show them this forum post.
Some thoughts.
You upgraded to W10. Normally, when you repair or install Windows it formats the disk, which deletes all the data on the disk. A key question therefore is how the W10 upgrade works. Does it just overwrite the Windows files? Or does it overwrite and destroy all the data files? Do you still have your other data files like PDF files, photos, music etc?
The file you posted has 4096 "correct" bytes followed by all zeros. 4096 is a significant binary number - it is 1000000000000. That is very interesting - it may be a page size or it may be the first block of the file (files are written in blocks). I don't think this is Writer corrupting the file. Did you un-delete this file? or is the file exactly as you found it when you tried to use it?
Can you open any other .odt files?
If the upgrade did not format the disk, and all your other data is still there, you may be able to un-delete some of the temporary files which Writer wrote while you were editing the .odt file, and then deleted when you closed Writer. Act quickly - they risk being overwritten the longer you leave it. Note that this only works if you were editing a .odt file - it does not work if you were editing a .doc file.
Using RECUVA to un-delete Writer .odt temporary files which are now deletedAnother on RECUVA These may also be helpful.
Using 7-ZIPInside an odt fileHints on how to prevent it happeningAlways set AutoRecovery to save a copy of the file every few minutes while you are working on it - it protects you against things like power cuts, OS freezes etc. Tools > Options > Load/Save > General ...
Always?? set Create a backup copy to ON - this keeps the previously saved version of the file fred.odt as fred.bak in the Backup folder. Tools > Options > Load/Save > General ... The Backup folder location is shown by Tools > Options > OpenOffice > Paths ... You may need to switch on Show hidden files (Control Panel > Folder Options > View ...) to be able to see the folder and its contents. Why the ??? Because you should remember that highly_personal.bak will still be in the Backup folder long after you have deleted highly_personal.odt!!!
If you have no luck, I could logon to your PC using Windows Remote Assistance and see what I can find. But it would be MUCH easier for someone to do it sitting at the PC.
