To move:
Open the folder, hold the Ctrl key down and press the letter A. This will
select (highlight in blue) all the files. Look at the menu on the left
under Files and Folder tasks and click on Move the selected items. A window
will open, browse to select the folder you want.
If you only want a few files, click on the first one to highlight it, remove
your finger from the mouse button, move the mouse pointer down to the last
file you want and click on it. This select all the files in between.
If you want a few files here and there in the folder, same thing, but
instead of using the Shift key, hold the Ctrl key down as you click on the
individual files you want.
To sort by date. Open the folder
Click on View on the top bar (not the Views icon) of the second top bar.
Click on Arrange icons by on the opening menu,
Click on Picture taken on.
Click on the Views icon on the second top bar.
Click on Details.
Clicking on the column header "Date picture taken" will change the listing
from ascending/descending. Set to what you want and then you can return the
Views to thumbnails.
