Hi,
Thank you all for your reply!
True! In the meanwhile i remember to opened the windows task bar and saw a bunch of word documents tasks opened, it was that what was filling my disk, so I changed the "CreateObject("word.application")" to "GetObject("word.application")" and it worked, but since the code is not optimized it takes around 1h to do 150 documents....
macropodit was that code that I was looking for, it works like a charm! thank you very much!!!
