Unreliable - Deleting multiple files/folders with the same name?

Question

I have recently found when trying to delete folders with the same name it is unreliable, is there a better way, ie termin that would work for the following...
I have 1000's folders with sub-folders to delete...
Please see screenshot each folder is identical apart from 'copy #' at the end of the folder
1. using search in top level folder toobar for "instructions"
2. 647 results are retuned
3. Select all and [cmd] [del]
4. Repeat step 1 but some folders are still are found.
Any ideas ?

Go ahead and doubt if it makes you feel superior.
For others:
If your pom has this:
<dependency>
               <groupId>javax.faces</groupId>
               <artifactId>jsf-api</artifactId>
               <version>${jsf.version}</version>
          </dependency>
          <dependency>
               <groupId>javax.faces</groupId>
               <artifactId>jsf-impl</artifactId>
               <version>${jsf.version}</version>
          </dependency>
where jsf.version = 1.2, change jsf.version to 1.2_10
