On some of our PC, the Excel11.xlb file is very very big (20 to 50Mb) and
its size increase by 30k each time Excel is closed!!!
This have a very bad impact on Excel Performance especially at the closing
time
I know that we can delete the file and then get a new one that is 40k only
but how to stop the 30k increase mechanism? To which setting can be linked
this feature?

Thanks for your help
