[QUOTE=Da_Taxman;2173541]POssibly in Windows the display of extensions is disabled, whereas Nero shows them…don’t know if that it is the problem…
If they are true jpg files, I would not change the extension, because no software will then recognize the files anymore.[/QUOTE]
[QUOTE=Dogg;2179823]If the files don’t have an extension (ie: .jpg) then nothing would be able to open them. Windows only knows how to handle files (ie: which program to open them with) based on the file extension.
Windows by default hides the file extension.[/QUOTE]
If you don’t want the file extensions displayed, simply enable
[B]Hide extensions for known file types[/B]
As Dogg said, this is enabled by default.
