Unzipp, Change Pictures and Zip a Storyline File

Hi there,  

There is a possibility to unzipp a Storyline File. (Not the published version - i'm talking about the .story file)

I experimented a little bit with that method and swaped some .png's and .jpegs

It's a lot faster in big Files with many pictures than changing the content in the Storylinefile itself. 

I also zipped the Storylinefile and it was possible to restore the File. 

My question is:

Is this a supported method? Could be there problems with the File itself in the future?

 

I am using Storyline 360 and Storyline 3

best regards

Sam
