+.SYNOPSIS
+    Script is designed to organise pictures into folders using the date-taken.
+ 
+.DESCRIPTION
+    Script organises pictures into folders using the date the photo was taken. It requires installation of EXIFutils. The script extracts the date-taken from the EXIF properties of the picture and uses this date to create a folder. The picture is MOVED once the new folder is created.
+   
+    EXIFutils v3.0 (non-licensed version) was used when building this script. exiflist is called for each file processed due to the limitations set for the non-licensed version of EXIFutils.
+   
+    The author takes no responsibility for correct functioning of the script with any other versions of EXIFutils.
+   
+    ***It is STRONGLY recommended you back-up your pictures before using this script.***
