Uploading Icons

I have svg icon file that was saved as ZIP
Accessing Icon Library using the Icon plugin, I uploaded the ZIP but cannot see anything in the Custoim Icons List.
I have cleared cache and logged back in but still cannot see it.
When I try to report, Gridbox says file already exists.
Can you provide help with the issue and also tell me where the uploaded files are saved in case I need to delete via FTP?

Thank you
