NI unzip changes file date and time stamp

[RTSLVU]

A coworker this morning asked me about the NI-Unzip VI.

It turns out that when the NI unzip VI unzips a file it changes the file dates to the date the file was unzipped.

He also noted that NI-Unzip seems to be calling the Windows touch.exe to do this.

The diagram for NI unzip is locked and password protected so his attemp to change this action blocked.

Does anyone know a way around this? Either to make the NI Unzip stop changing the file date or the passwork to teh unzip vi?

Hi,

I don't think NI will give you a password for it's protected functions...

So you can:

- use "System Exec" with a command line version of a ZIP tool of your choice to unzip files

- make your own "Unzip" VI with calls to a "unzip"-DLL of your choice

Choose the one that is easier to implement for you

OpenG should have some ZIP VIs, which I believe call the DLL.

As TST mentioned, check out the OpenG Zip Tools library -- it's very full-featured.
