Here's a few various ways I can think of:
1. Shift+Click highlights all files between two clicks.
2. Tools > Reports > HTML Files.
If your "_000" split files are all very tiny, you should be able to sort by File Size and see them all appear there.
Then do a nice Shift+Click to highlight, then Right+Click > Delete From Book.
3. Unzip the EPUB (it's just a specially put-together ZIP file), open the files in Explorer, then search + delete.
Create new EPUB and reimport all those files in?
