yes .. unfortunately that would have been my next suggestion, to remove the contents of the incomplete folder completely.

I know in your case it was accidental, & likewise people including myself 'accidentally' choose the wrong file. But in general, try to learn to recognise what sizes & how spam names-itself after your search terms; see Virus thread: Typical virus spam file sizes - Make a note of them (click on blue link to see) for some hints on such sizes.

When search results come in, the first thing I usually do is arrange them by file size by clicking or double-clicking the size column heading (so largest files show at the top). You need to re-click that heading if you re-designate any files as not junk or as junk to reorganise them in the list. I always have junk show at bottom of search results just in case the junk filter gets it wrong, which is frequent of course.

Well, thanks for your help...hopefully I'll figure something out.

Do you think it would be a good idea to take my laptop into the Apple store nearby and see if they know anything to do?
