I have fixed a bug in my Bulk Delete WordPress Plugin, which deleted drafts in a particular category even if only posts were selected. Thanks to one review for reporting it.
If you want to only delete posts in a category and not drafts, then you need to update to the latest version.
You can download the latest version from the Plugins home page. I have also uploaded the Plugin to the official directory to make your update process painless.
I am working on other features for the Plugin like deleting posts waiting for pending reviews etc. So stay tuned 
hello sudar,
will this bulk delete plugin supports deleting all comments at once!!! i had made a simple wordpress based site for my friend where there are nearly 2000 comments. where there is no askimet activated. I have already installed this bulk delete plugin but was unable to find the exact thing.
i had found the another process from phpmyadmin to delete the all comments , but i want to do it from bulk delete.
@Pracas,
Right now the Plugin doesn’t support Bulk deleting comments yet. It is in my TODO list and I will implement it when I get some free time.
