Block Reference Itself, batch fix

I have recently downloads a pile of files, blocks for inserting, symbols. Apparently all files have block in them of the same name of the file name. Thus, upon inserting a file I get the error "block reference itself" and will not insert.

Is there a means of removing the block in the file in a batch method? Since there is over 8700 blocks, I do not want to open each file, explode, purge, save, individually. Looking for a batch method that basically does the same thing. Or some other method to not only remove the error, but also to avoid the purging nested block on layer problems.
