If you want to insert the document name in Word’s header or footer, follow these steps.
1. Click File, Info, Show All Properties. This is where you can add metadata about the file, such as the document name, owner, date and keywords.
2. Enter the document name in the Title Field (i.e. first field). Close this and return to the Word document as usual.
3. On the View menu, click Header and Footer to activate the header area. Click where you want to enter the file name.
4. From the Insert drop-down menu, select Document Info, Filename. This adds the Filename to the header or footer.
Did that work for you?
