     @ponapalt It looks like minizip-ng can read zip files directly from memory, so it looks like I can just read the zip file into memory and open and traverse itI'm hesitant to say that some nar may be very large, so perhaps there should be a limit on the size of the nar that can provide previews to avoid unnecessary file reads, but I'm not sure how big a nice size limit would be. how about 32mb?

     @steve02081504 Since the size of the NAR tends to increase each year, it should be able to read about 2MB-4MB.file mapping object with file handle may help you if you want to read large file but not want to allocate large memory.
