My girlfriend is writing a Word document for a homework. She's using the old .doc format as required by her teacher ( :'( ). At some point, the .doc file went from 150 kB to 2.6 MB with no noticeable change (seen in Dropbox history. Sadly, Word's comparison function fails because Word crashes). From that point, she was unable to save her document without crashing word...
I converted the .doc to docx, unzipped it, and found a 18 MB document.xml file ! I can't even format the xml properly because it crashes Notepad++, but I can see that the file is filled with the same xml tag repeating over and over :
<w:p w:rsidR="002A70E5" w:rsidRDefault="002A70E5" w:rsidP="00565ED9"/>
Do you have any idea what could cause this ?
EDIT: Here's the docx
EDIT2: The motivation for this question is more curiosity than looking for a fix. Thanks for your answers though.
