Thanks to all of you providing me with lots of hints on not to forget passwords or prepare in 
advance for it.
The SW I am using to crack an xls-file runs already for more than 60 h in the background. It's a 
nothing to loose only to win job. 6 or 8 digits alphanumeric no special characters is the PW used.

Thereafter I will make a test cracking an LO file.

The only thing which makes me wonder is that there are PW removing SW commercially availabe which 
run demos and claim within 10 - 30 sec they could remove the PW but open the xls file only when I 
purchase a full license.

Does someone has experience with such a SW?
