A friend of mine sent me a file attached to an email with a ".png" extension, but now my computer will not let me delete it. I've tried Windows Explorer.. won't work, deleted the entire folder it's in to the Recycle Bin, but when emptying the Recycle Bin, it still won't delete that file. I've even tried to go thru DOS and delete it, but it tells me "access is denied". What gives with this file? I've run Norton Anti-Virus on it to see if it might be a virus file, but it reports nothing? Any help would be appreciated..... ------------------ Barry Floyd Floyd Entertainment Group Lebanon, Tennessee Stardust Drive-In Theatre Watertown, Tennessee

A "ping" file (.png) is similar to a .gif. It is used under the same conditions/constraints as a .gif. If memory serves it stands for "Packaged Network Graphics".Two reasons to use it:
- It's not patented. The GIF format is "owned" by Compuserve (or whoever owns Compuserve now). They demand their royalties from everyone who wants to write an application that uses it. Ping is royalty free.
- Ping is better than GIF. Depending on the circumstances, ping files will be as much as 20-30% smaller than GIF. Ping compression is considered a lossless form of compression, depending on the paramerter settings at the time the file is originally written.
Some browsers don't read pings, or you may need a plug-in or something, I'm not sure. I haven't had a problem reading any .png files. QuickTime will read pings. You can download that free from Apple.com
