What do you mean terrible? I've provided a post with complete detail
Complete detail is when the line says "My name is Peter"
and you provide information that says something like "My name is xxxxx"
instead of "abc 1111 data"
The reason why that is so important, is that Batch file code often changes when the data/text changes.
The code I provided above just shows how you can separate the filename tokens - it was quick to post.
