Not sure if you can do them in batches but the quickest way I`ve found to do them individually is this.
In Explorer select your first file & right click.
Press Home Key and type in "Holiday - " as your example.
Before you press enter highlight and copy (either with a right click COPY or CTRL+INSERT keys) the wording you have just typed. This puts it on the clip board.Then press ENTER and the first file is renamed.
Now right click other files individually select RENAME then HOME and paste from the clip board. I choose to use the keyboard shortcuts because it is quicker and I can get into a Rhythm.
Hope this helps.
