Hi. I recently noticed that at least some of the PortableApps apps now have "legacy" subfolders as well as non "legacy" subfolders.
For example, Stellarium now has StellariumPortable\Stellarium
and StellariumPortable\StellariumLegacy
folders. The same structure is present for Rednotebook.
Can you explain a little about this new folder structure?
If an installation is only going to be used with a single OS, can one or the other subfolder be deleted to make more free space?
