I tried already to copy and paste the file, but it is probably to large for the memory and it doesn't work.
As i said - never mind. i will not bother with this issue for the time being.
The 2 Mb pdf file size is good enough to put it on the Web, and that's what is important.
BTW - Total Commander is an appliance similar to the Norton Commander from the early computers and very helpful for managing the files.
