Find files buried in layers of archiving\compression?

[boardtc]

I have a lot of zip files, some containing multiple layers of tars & gz files. My goal is to search all these to come up with a list of all the contained .jar files. Is there any way of doing this with Everything

No, not at all.
Everything and other such tools read the Windows MFT or directories
and these entries do not contain any info about the content of archive files.
