I would like some help and pointers about how to minimize the size of a virtual app. I tried to create a portable app (the version I found in the Public Virtual Apps being the previous one, I wanted to update mine) but my app turned out to be quite large compared to the one in the Public Virtual Apps library. I guess it is due to all the programs present on my machine despite the fact that I closed all running programs before running Cameyo to try to reduce the size of snapshots. It helped but not enough. I could not find the relevant information in the help pages. I must be missing something and I would very much appreciate if someone could point me to the right direction.
Using Package Editor, you can delete folders and files that you are sure have nothing to do with your package. See documentation here.
For future reference, you may want to consider these alternative options: 1. Submit the newer version of the installer to Online Packager.
2. Build your package in a clean virtual machine.
3. Use -GhostCapture parameter. See documentation here.
4. Use -Patch parameter on current package to be updated. See documentation here.
5. Update from within the packaged software itself.
If choosing option 4 or 5 and you would like to save the changes back to the original package, use -Repackage parameter. Just be aware that this will save all changes to the package. See documentation here.
