|I think what Jennifer meant is that you can't delete files from within the Word program itself. You have to go into the computers file system ("My Computer" or "Windows Explorer").|
Can I double check the exact procedure you are using?
You left click a file a file you wish to delete, to highlight it. You then hold the Ctrl key down and left click any other files you want to remove, so that all of your selection is now highlighted. You then take your fingers off the keyboard, right click any highlighted file and delete - they should all vanish. [You can also remove files from the selection using the Ctrl key].
To delete a block of consecutive files you left click the file at the start of the block to highlight it. You then hold the Shift key down and left click the file at the other end of the block, which should highlight the lot. You then take your fingers off the keyboard, right click any highlighted file and delete - they should all vanish.
If you want to delete all files in a folder you left click one of them, then press Ctrl & A (together) which will highlight them all. You then take your fingers off the keyboard, right click any one and they should all vanish.
The above applies to folders too. Is this what you are doing? Sorry if I've told you what you already know but I wanted to be quite sure you were not doing something slightly different. If you depart from the procedures given above then it is quite possible to get copies arriving.
some other bloke...
