I'd suggest using four spaces instead of tabs ;-)

Why not do the whole thing in one loop? (Ignore my prev post suggestion for final
renaming loop just for spaces):

#XXX# untested !!
import re, os
percent2f_n_bad = re.compile(r'%2f|[*?<>/|\\]') # look for bad chars too
for root, dirs, files in os.walk('/home/rbt/scripts'):
     for fname in files:  
          newfile = percent2f_n_bad.sub('-', fname)
          newfile.strip() # and the space thing
          if newfile != fname: # you really only need to know if something changed, right?
              newpath = os.path.join(root,newfile)
              oldpath = os.path.join(root,fname)
              os.rename(oldpath,newpath)
              print `oldpath` # backticks to get quoted repr, to see spaces
              print `newpath`

Or am I missing something?
