adding a folder to a zip file



Any update on this?


I'm trying to do exactly the same i.e. create a zip file with preserved folder hierachy (like any zip compression tool would do!).


The OpenG package has a function which is supposed to compress a whole folder but it doesn't work (error 8 - problem with file permission).


I can't believe a function like this doesn't exist in Labview.


Does anyone know a working function to create a zip file (with comments and passwords) while preserving folder hierarchy?

the "configure file" sub vi does not do anything, it just gives a file placement location, it can be disregarded

Hi all,


I'm writing a VI in LabView 2013 that zips a folder with the same subfolder tree and it's working fine except for empty folders.


With the "Add File To Zop.VI" in the LabView library I can zip all the files I need, but if the source file path is a folder the VI doesn't do anything.

I'd like to add empty folders to the zip, does anybody knows hot to do it?

Hello Marcello,


Unfortunately, the native LabVIEW ZIP API does not currently support adding an empty folder to an archive. However, I believe the OpenG ZIP API extension does allow you to compress a complete directory hierarchy. Have you used an OpenG package or the OpenG add-on ZIP API before?

I hope this helps!

I've never tried before OpenG libraries but I will..


Meanwhile I'm using an external portable zip tool called by "System Exec.VI" but I'd rather to find an internal LabView tool.


Thank You very much
