I just took a capital letter one and resized it to see if my image viewer program is doing this conversion, but it didn't change it to lower case. They seem to be the same type of file. ?
Nvm, the lower case is from my smartphone, the uppercase is from my camera.
But I still don't know why there are two different types of extension of the same file type.
True, but I was wondering if those are the same file types. Google search only talks about JPG vs JPEG, not JPG vs jpg.
Windows explorer doesn't have an extension pane. Every file is capital .JPG in list view.
The properties show the respective Dopus case sensitivity in brackets.
This is confusing, but I get the feeling these are the exact same file types, but with weird different extensions but the same extensions. The problem is I can actually divide these two types by the lister column (ext) filter. Since they are the same file type that probably isn't ideal. But it might come in handy, come to think of it, since that difference indicates the device source, and I don't have any other column that handles that particular metadata field, I don't think.
Ok. I found the 'Camera Make' and 'Camera Model' folder format fields too.
But I discovered my folder didn't auto-set to the 'Images' type. I will have to investigate that.
