I've been trying to find a way to zip folders (that contain numerous TDMS and TXT files) on a cRIO RT platform.

Zipping the same folders on windows results in zipped files 10 times smaller.

It would be fantastic if I could do the same on the cRIO before these files have to be downloaded to a computer (through FTP which takes an extremely long time and freezes for several minutes the computer that receives the data).

Any help will be greatly appreciated!

For anyone who's pursuing the same goal, I have received some feedback from NI which I am including below.

If you have succeeded to zip files on an RT platform before or know how it can be done please share.

>> The Zip VIs that are available in LabVIEW are aperating system dependent and they do not work on the RT-OS's. So the bad news is that, LabVIEW does not currently ship with RT zip functions. Therefore, officially the answer is no!!

>> However, there is some good news, another customer provided a solution on our discussion forums. The OpenG Zip library was reported to work well on LabVIEW Real-Time - both the Pharlab and VxWorks systems. Please peruse the following link. I would recommend reading through the entire thread, but the useful links appear on the final page.

I will try the above and if I succeed i will update this thread.

Thanks

Is this still an issue, no zipping on RT?

And will OpenG work on Linux RT?
