Hi. When you're in build mode and add an image file as a source, ImgBurn displays this warning:
You've only selected 1 file and it looks like it's an image file!
'C:\1\test.cue'
You're in 'Build' mode, are you sure you want to create a backup of this image file rather than just burning it normally?
Note: If you want to burn it normally, click 'N
The word "backup" made me think that it will create a copy of the source image, possibly in different format. I think it should say:
"You're in 'Build' mode, are you sure you want to build a disc containing this image file rather than just burning it normally?"
