[galaxy-dev] Deleting non-.dat files from Galaxy database

Hi all, These are some of the data that I have generated via Galaxy while I was experimenting with it. dataset_186.dat.bam dataset_265_files dataset_222.dat.bam dataset_266_files d dataset_346.dat.stat dataset_194.dat.fai dataset_267_files dataset_346.dat.temp dataset_727.dat.stat dataset_272_files dataset_727.dat.temp dataset_150.dat.bam dataset_273_files Is there another way in Galaxy to delete these without having to directly manipulate the database? Thanks! CL
