If you're having more luck with a general search for files (rather than looking in the default saving/sharing locations for your LW version) - look for whatever video formats you might have. For eg .avi, .mpeg, .H264, .wmv, .mov, .mkv or search for the video titles

And for photos, have a search for .jpeg or .jpg, .gif, .png, .tif, .tiff & see whether your files show up

PS We're having your kind of weather here today & it's horrible (still only 12º at half past 1 & it's been hailing all day)
