For gods sake, do this in a python script!

cutoff = DateTime()-45
for file in context.Files.objectValues('File'):
   if file.bobobase_modification_time()<=cutoff:
     context.Files.manage_delObjects([file.getId()])
return context.filelist_html()

or, more compactly:

cutoff = DateTime()-45
context.Files.manage_delObjects(
   [file.getId() for file in context.Files.objectValues('File')
    if file.bobobase_modification_time()<=cutoff ]
   )
return context.filelist_html()
