How do you upload a .gz file to your site. Where do you go in cpanel to do this? .gz files are usally a full sites database correct? Thanks much

.gz is a gzipped archive. What's archived - it depends on the person who created an archive. I think you should rephrase your question now since you upload any file the same way via Cpanel. If you want Cpanel to do something with the file afterwards - please explain it more clearly.

Yes, maxymizer is correct. State your exact goal, what you know, and what you need to know. That will help the community help you.
