Deleting file in QuickTime Player 7.6.4 ( free version )?

Locate the file in Finder.
Right-click on the file.
Move to Trash.

 

First, any file you locate in Finder can be deleted. If you don't see "Move to Trash", just drag the file to the Trash icon on your Dock.

You don't have to "transfer" pdfs between Adobe Reader and the Preview app. You open the pdf with either app, whichever you choose. You can right-click (or Control-click) any file and choose "Open with" to choose which app you want to use to open the file.

Preview works just fine for pdfs. It launches faster and uses less resources than Adobe Reader. Some pdfs may not display exactly the same in both apps, but usually they will.

 

That's what the forum is for: questions, both elementary and complex. Do you have the file in question already open? If so, quit Adobe Reader and/or Preview and then try to delete it. If you can't delete the file after that, see here:
You can't empty the Trash or move a file to the Trash

 

I meant for to right-click in Finder to "Open With". If you're looking at an email, you're not in Finder. You first need to save the file to your computer, then open it. If you click on the pdf in the body of an email, it will open with whatever app your browser is set to use.

 

hi peewee12345,
I think we're now not sure where are you trying to delete the files from. Could you please tell us what are the steps you do to see the file ?

 

It sounds like if you select "Download", it will download it to your desktop, where you can right-click (Control-click) it on the desktop to "Open With".

 

That's your answer. Choose the download option.
