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.
