This script also lets us scan for different file types; here it is picking out the smallest
and largest text file from one level up (at the time I ran this script, at least):

C:\...\PP4E\System\Filetools> bigext-tree.py .. .txt 1

..

..\Environment

..\Filetools

..\Processes

..\Streams

..\Tester

..\Tester\Args

..\Tester\Errors

..\Tester\Inputs

..\Tester\Outputs

..\Tester\Scripts

..\Tester\xxold

..\Threads

By bytes...

[(4, 2, '..\\Streams\\input.txt'),

(13, 1, '..\\Streams\\hello-in.txt'),

(20, 4, '..\\Streams\\data.txt')]

[(104, 4, '..\\Streams\\output.txt'),

(172, 3, '..\\Tester\\xxold\\README.txt.txt'),

(435, 4, '..\\Filetools\\temp.txt')]

By lines...

[(13, 1, '..\\Streams\\hello-in.txt'),

(22, 1, '..\\spam.txt'),

(4, 2, '..\\Streams\\input.txt')]

And now, to search your entire system, simply pass in your machine’s root directory
name (use / instead of C:\ on Unix-like machines), along with an optional file extension
type (.py is just the default now). The winner is...(please, no wagering):

C:\...\PP4E\dev\Examples\PP4E\System\Filetools> bigext-tree.py C:\

C:\

C:\$Recycle.Bin

C:\$Recycle.Bin\S-1-5-21-3951091421-2436271001-910485044-1004

C:\cygwin
