When I use the self extract functionality ,
the unzipped file always has a Date Modified value - earlier than Date Created in the file properties.
e.g .
Created : 
Thursday, November 04, 2010, 2:24:07 PM

Modified:
Thursday, November 04, 2010, 10:23:10 AM

I noticed the same behaviour in the foiles created by unlicensed - Sample Program and also the files created using the licensed dll.

Please let me know , if there is a solution.

Hello,

This is expected; the modified timestamp is from when the file was last modified before it was compressed (or the original creation date if the file is never modified), while the created timestamp should be the timestamp at the time of extraction (when the file was created on your hdd).

When I ran the unzip on the selfextract exe (Ext-test.exe) .. the resultant file (Final_test.sql)
had the following properties :

Created : Today, November 12, 2010, 4:05:46 PM
Modified: Friday, November 05, 2010, 10:36:44 AM

You can see, as mentioned in the beginning of this post that the date created / modified on the original file was :
Friday, November 05, 2010, 2:36:44 PM.

There is always a differece of 4 hours in the time stamps - after extraction.

Thanks
