This is a Win32 build based on the IJG utility CJpeg.exe 6b AltUI.

Features:-

• Runs in Windows XP, 98SE.

• Does NOT run in 16-bit native Dos mode.

• Long file names in double quotes can have embedded spaces.

• Outfile can be a folder name ending in slash.

• Syntax info is now context sensitive.

• Minimum abbreviations indicated with Capitals on the help screen.
  (Actual keywords are case insensitive.)

• More info in file error messages.

• Single keystroke for y/n response.

• If an error occurs, it waits for keyboard before closing window.
  (This gives you time to read the message.)

• Huffman Optimization turned ON by DEFAULT.
  
  

Use this utility as a Windows Explorer context menu command.

c:\utl\CJpegRJ.exe "%1"

If you copy the exe into the DOS path
then you can also use it in a Windows Dos Box.
