Name collision rules
   When making new names there is a chance of two files ending up with the same name.
  The default behavior is to fail and not rename the file but you can change this behavior by applying a different name collison rule. The rules are described below.

  Fail
  Don't rename files with a name collision. This is the default behavior.
  Ignore
  Attempt to rename the files even if there is a name collision. This might result in errors.
  Append number
  Will append a incrementing number grouped by similar filenames. If the resulting new names are as follows:
Foo.txt Foo.txt Bar.txt Bar.txt Bar.txtThe corrected names will be:
Foo.txt Foo_001.txt Bar.txt Bar_001.txt Bar_002.txt
  Append image sub second
  Will append the Exif value Image Sub Second (if present) to files with the same name. Can be useful when renaming images taken within the same second.
  Append pattern
  When using this collison rule a text box will allow you to supply a pattern containing tags that should be applied to the end of all files with a collision.
  New name
  When a collision is detected, generate a completely new name based on the pattern supplied in the text box. Tags can also be used here.
