Thank you for this script !

Just curious, is there any way these components can be archived/copied to some other location before deleting , is it doable ?

Hi @gopal9590

This script use internals of Nexus which were barely documented. I have no idea if it will be possible to extend it as you want.

Other approach might be to write for ex. Python script that will do something similar via REST API, but if I remember some date (like time creation or usage) were only accessible via internal scripts.

I can only wish you good luck ;)
