I am trying to get a listing of the files contained in a .rar (unencrypted) archive without unzipping the archive each time I want to run the script. There is a method to get the files listed in a zip archive, but since I'm using this for storage purposes, I am saving as a .rar for better compression.

This post describes a procedure by which one can obtain a list of the files inside a zip archive, but I can't get it to work with a rar archive. Any help would be great. Thanks.

For the task of getting the list of files in a rar, without extracting them, https://stackoverflow.com/questions/561107/rar-archives-with-java

(RAR license is restrictive about doing extraction.)

Hmmm, the documentation at https://github.com/radarsh/raroscope hints that it needs to be compiled into a .jar -- see the "Gradle" part

I found some sources online that said you could just change a .zip extension into a .jar, and Windows seemed okay with that. No joy referencing that jar though. Same error. I am trying to install Gradle, but it is really complicated (wish they just provided an exe!). Do you have any recommendations on making the .jar file?
