Hello Hani,

I use winzip with command line parameters. They have a free file wzcline.zip on their website which documents the options as well as provides
a more stable interface (I believe you need to register to use it, $30) I then run the command line and pipe the output into a txt file which I can parse/view to see if there are errors. Most errors, including having a file open should not prevent the process from finishing. If the file is open, it will back it up, but won't guarentee the data is not in flux.
