These files are stored within the APPX where a list of file paths from \"assets\" can be easily extracted... which should make it faster than storage access.\r\n\r\n*Test:*\r\nRun the below code to fetch a listing of all files under the \"Resources\" directory. Observe the log for the duration of this function.\r\n{code:javascript}\r\nvar startTime = new Date();\r\nvar file = Ti.Filesystem.getFile(Ti.Filesystem.getResourcesDirectory());\r\nvar listing = file.getDirectoryListing();\r\nTi.API.info(\"@@@ getDirectoryListing() duration: \" + (new Date() - startTime));\r\n{code}\r\n\r\n*Recommended Solution:*\r\nAn Windows APPX is really a zip file. We should open the APPX as a zip file and fetch/store all zip entries referencing files under the \"assets\" directory. This way we can have fast hash table lookups when doing existence checks and fetching directory listings.\r\n",

So, I wouldn't be surprised if APPX worked the same way.\r\n\r\nBut this should mean {{getDirectoryListing()}} performance should be roughly the same between the \"Resources\" directory and any other directory on storage, right? The only major difference is that we should be listing the encrypted JS files under \"Resources\" as well and merging that list with what we've grabbed from storage.",
