Restoring a broken .blend file (hex editing)

Managed to break a file that I spent like 16 hours working on yesterday by (I assume) having it reference temporary data in the first place. So I looked at the .blend file in a hex editor to figure out where exactly it’s looking for the file with the mesh I had copied in, and found a couple instances of this data (converted to ASCII): ‘C:\Users\user\Desktop\blender.p\Temp1_3905_generic_male.zip’

The ‘.p’ you see there is actually bytes 00 70, so that part isn’t ASCII. The question is, is there any way of knowing what the actual path is that this data represents? Or how I can modify it to point to where that archive actually is now? I’m on Windows 7, Blender v2.78c. Thanks in advance.
