Not everyone has pkzip or similar installed...I just found that out! Using my someone else’s computer, I needed to unzip a file. I have to know a password to install software on that computer...and don't know it. So......
I found My Web Zip, which will zip or unzip files. Now I'm unzipping one I had converted from PDF using the site mentioned in the previous post--so large they zipped it to send it to me (in short order, I might add).
I now have the images from that file that I needed, so all I have to do is to copy and paste them into PowerPoint. Otherwise it would have meant time taking screen shots and cropping them.
Thank goodness for FREE online tools!
