of time in which the desired files are located.  Alternately, you may

you have selected the range, choose the files you wish to restore using
the interface in the botton half of the Restore tab window.

directory in the Browse directory field.  You may change the filter
for finding the desired files by entering a filter into the Filename
filter field.  To refresh the displated files in the window, click

calendar icon.  The button in question (the Refresh button) has an
icon consisting of a white square with two green arrows going clockwise.

To select the files you wish to restore, click in the checkbox next to
each desired file or folder.

When you are done selecting files, click the Restore button in the 
bottom right-hand corner of the window.  The Restore files window will
appear.  Confirm that the "Restore everything to its original location"
radio button is selected, then click the Start Restore button.
