Re: Keep LibreOffice even if you move to MSFT [Was: MS Office? Faster?]
"Documents became fatter and fatter every day. Many, many megabytes. I learnt a little trick. From time to time I opened the current fatty in LibreOffice, made a tiny change (e.g., added a space somewhere or corrected a typo), and saved...
SHHHHRRRRRRIIIINNNKKK! All the extra fat is instantly gone."
Just save in DOCX or XLB format - beats Libre Office for size every time!
