I was waondering which one should I download at the wordpress .zip or .tar.gz and wats the difference between thhe two..?
The .tar.gz is the alternative gzip format - just a different type of compression. It boils down to personal preference I guess.
No difference really, just different compression as CountryBoy wrote. I always use zip though,no reason though.
Well if you have shell access to your host, you could wget the tar.gz file and unzip it right inside your host so you can avoid to unzip it in your local computer then upload it in your server. If you don't have shell access (and apparently you don't) save the hassle from requesting one as you will still need to learn all the commands. Just download the .zip file in your local computer, unzip it and upload it to your server. Cheers
