Hi @Shiv ,
Based on your description, I don't quite understand your needs.
Do you want to synchronize all listids in the site to file explore, can you describe further?
My understanding is that you want to store all listids in a site to file explore in the form of files.
If this is the case, then you can use powershell to get all the listids in the site.
For details, please refer to this article:

Or, do you want to export all the items in the list to a csv file, and then store the file in file explore?
If so, you can refer to this article:
