So, I have alot of books of various formats and i only want them in epub format. no problem Calibre converts them ez as pie. A problem however occurs when I try and delete the files manually from the files aren't updated and removed in the calibre database.
I'll give an example

1.)I have lets say 100 file(s).pdf
2.)I convert file.pdf to Epub
3.)I use a dos prompt and a little dos magic and I delete all of the .pdf files that reside in this directory.
4.) Now my calibre says I have all these pdf's I don't actually have, but I go ahead and add the new epub versions of the books anyway and now the library states that I have epub and pdf formats of these files, which is inaccutate and annoying when you are trying to convert everything to epub.

Is there anyway to mitigate this problem? My temp work around is to go into the Calibre Library folder and delete the metadata db file and readd all of my books which takes hours... on quad core system with 8gb of ram.

I want a simple way of Converting all these files, deleting the original, have calibre reflect the changes I have made without having to trash the entire metadata file. The only thing I can figure to maybe try is to go into the metadata file and manuall delete all .pdf entries but looking at that file it would be a nightmare......
