Recreate files but without content to target drive

Alright fellas,

2 hours spent trying to fix the script and here are the results for the python script!

--- ---08:25:33 PM
08:25:46 PM
a grand total of 13 seconds!!!

Zipfile about 12 MB. with 54827 files (created a few files since last count)

Things I had to fix:
bugfixes
 modified time errors
 path length exceeded errors

resolution:
 #set time to unix epoch 0 = 'Thu Jan 01 07:00:00 1970'
so there will be some files with incorrect timestamps in the zipfile

I hope this helps everyone... though I still got some warnings while running the script... probably due to windows handling of files and or paths...

Here's the final code so far

I hope you all enjoy this. I'll attach the exe as well, though I can't make any guarantees for it.

Nice job, vixay.   :D

Hey guys, love the software in here.  I am currently using zero zipper to create the 0 byte files but I was wondering if there were any command line options that I could use so that I could utilize zero zipper in a batch file.

I tried to use vixay's exe, but i'm not sure I completely understand how to use it.

Thanks for your help

skwire:
You should be able to use vixay's exe for what you want to do on the commandline like this:

makeTreeZip.exe target-zip-file.zip mydir1 mydir2

Let us know how that works out for you.

v1.0.5 - 2011-10-24
    + Zero Zipper now preserves both the modified and created timestamps for
      files and folders within the zipfile.  (Thanks, Wayne)
    + Added drag-n-drop to the two edit fields.  (Thanks, Wayne)
    ! Fixed 120 DPI display issues.  (Thanks, Wayne)
    ! Fixed a parsing issue where not all files would get cloned into the zip.
