Ever wondered what's inside some of those binary files on your system (binary executables or binary data)? Several times I've gotten error messages from some command in the Solaris system, but I couldn't tell where the error was coming from because it was buried in some binary executable file.
The Solaris "strings" command lets you look at the ASCII text buried inside of executable files, and can often help you troubleshoot problems. For

Good going guys.
About Rawstudio:
To get the best quality out of your digital camera, it is often
recommended that you record your pictures in RAW format. This format
is mostly specific to a camera and cannot be read by most image
editing applications.
