How would you change ***.pdf to ***.001?

I'm lost... I needed to change a file to pdf. file to

Video, somebody told me I should change the name

of ';***.pdf'; to ';***.001';, my problem that it only says

';***';, but opens with Adobe Acrobat...



So how would I change the file type?

In Windows you likely need to turn off the hidden file extensions.



Open Windows Explorer and choose ';Tools'; then ';Folder Options'; and the the ';View'; tab.



Uncheck the checkbox that says ';Hide extensions for known file types';.How would you change ***.pdf to ***.001?
find the icon that opens this file and right click on it. Then select ';rename this file'; Click on it and rename it'; ***.001';



Hope it Helps!!!
