I uploaded a zip file but there's no option to unzip it. I just get the option to rename or delete it.

Please advise.

Uploaded or downloaded? If it's on your pc to a right click to extract it to the location of your choice.

Windows (later than XP) usually has a built in extraction setup now so if you're on XP or older you'll need to install software to unzip your files such as Winzip or Winrar etc. I think CoffeeCup has an old zip program too, not sure if it's a sale or free item to maybe check out if you need it.

We still have one!

Oldie but goodie, it works

Heeeeeyscafe. Phew! some avatar. If I understand correctly you wish to upload a zip file and extract online. I use this utility I created. It stores projects as well. It's free and I would appreciate feedback on it. The description file has some spelling errors but Beta testers are hard to come by. I made it to upload the form files and folder. which I have yet to do. You can contact me via this form http://inkmon.org/links.html
