I have some 404 errors also. I cannot figure out how to get rid of them but was told they will not effect ranking in google. Hopfullu that's true.
The only ranking error would be if your sites were reflecting PR and you removed them. I would try some .htaccess changes to redirect the removed pages to at the very least the homepage. You never want the user to land at a dead page.
but i thing it's not good way to direct remove URL google webmaster, first you block URL through robots and after then you can remove from webmaster tools.....
How Can I Block All Not Found 404 URL Through The No Follow Robot.txt. Will You Plz Share Complete Procedure.
I would do it via htaccess. Where is your root domain & where are the files you removed? Are they in the root me.com/xxx.html or are they in a directory /somedirectlry/files
If that many number of URLs are not found then it means that there is a serious problem with the internal linking of your site. That much number of URLs means that Google will not take your site seriously.
After a while the search engines will eventually figure out that the pages have been removed, but you would have had better luck doing a 301 redirect
