Thanks so much for your help, you got me started and I finished it with some
help from others as well. For anyone interested the working code is:
--
#!/usr/bin/python
#Author: Evan Carmi
#Date: 20060102
#Purpose: To uncorrupt Mozilla Thunderbird mail index files.
#Version: 1.00
import os, time, glob
srcRoot = 'f:\\test\\mail'
backupRoot = os.path.join(os.path.dirname(srcRoot), 'backup-msf',
time.strftime('%Y%m%d%H%M%S'))
for root, dirs, files in os.walk(srcRoot, topdown=False):
sources = glob.glob(os.path.join(root,'*.msf'))
pairs = []
for source in sources:
# If srcRoot is /foo/bar and source is /foo/bar/baz, let relativeSource
equal /baz
#let relativeSource be equal to the remainder of source when you take
away len(srcRoot)
idx = len(srcRoot)
relativeSource = source[idx:]
# Then let destination equal /quux/baz if backupRoot is /quux
destination = backupRoot + relativeSource
# relativeSource begins with a path separator, so os.path.join will
misinterpret it.
pair = (source, destination)
pairs.append(pair)
for pair in pairs:
os.renames(*pair)
# This is functionally equivalent to os.renames(pair[0], pair[1])
