A script to find all files of a specific extension.

[spohnz]

I wrote this to find a couple of files I had thought were missing. 


import os

def oswalk():

    f=open('AllPortableApps.txt', 'a')

    for folderName, subFolders, fileNames in os.walk('C:\\'):

        for x in fileNames:

            if x[-3:].lower() == '.py':

                f.write((folderName + '\\' + str(x) + '\n'))

    f.close()

oswalk( )

if you need to change the .py to a .exe or something. Mind that the string  is striped to the last 3 characters (-3) so change that to -4 instead. 
1st line imports the OS
2 writes a quick function
3 creats and opens a file to store the result in. the 'a' is append. We are appending (adding) each find to the file. 
4 starting search in the root folder C:
5 taking each file name as it loops and seeing if the last 3 characters match '.py'
6 writes to f, which is the text file we stored as f on line 3
7 when finished, it closes the file. <-- always close your files.
8 run our function in this script.
Hope someone finds this useful I did.
