Re: [libreoffice-users] Re: how to crack a PW in LO?

I meant xls files in MS EXCEL 2003 when I wrote about the short times needed to open them. I 
protected them against opening.

I never tested a LO file so far - hope I never have to!!!
Here are some links I checked, however I don't recall what was the result for each link. Most of the 
links I deleted. I just searched for "password remove excel"
