Sort only zip files in a folder and then later extracting event logs from each zip file

Question

Hi friends,

Scenario : One folder with multiple files inlcuding txt files,zipfiles and xml files is present in my system.

I am using dotnet 3.5 and Windows XP.

I need to consider only zipfiles and sort them in first modified format and put the zip filenames in an array on creation time. i.e the zip file created first in starting of array.

Second Scenario : From each of zip files I need to extract eventlogs and process them.

Please let me know if anyone knows way.

Thanks in advance.
