If there is only one bookmark then I need to delete it.

Hello,

I have a folder of files having over 8-10 thousand pdf file on it.... most of these files has only one bookmark on them but maybe around 1000 of them has multiple bookmark on them...

I need to split these files into separate file using top level bookmarks. Problem/bug that Adobe Pro split function has, is that for all those files with one book mark it creates duplicate file for it.... i.e. there is a file called A.pdf with one single bookmark on it called BM.  Now when I ran the Split function to split it using top level bookmark, it creates another file called A_Part1.pdf in the same folder now in the same folder I have two identical file called A.pdf & A_Part1.pdf.  I do not need duplicate file with two different name.  I need to stop this duplication of file... if there is only one Bookmark then splitting operation should be skipped so I only have one file in the folder called A.pdf or if it creates A_Part1.pdf then it should delete the original file if there are no pages/zero left on the Original file.

Can Adobe fix this bug or somebody help me to over come this dilemma?

Regards,
