File names arbitrarily changed during Import - why?

[Intermodalist]

Last night as I improted several hundred images from a day of scanning Kodachrome transparencies into 160-180 mb uncompressed digital files, each with its own very specific file name, LR went from importing using the file name I had created to arbitrarily making the file names "untitled-(sequential number).tif". I have imported thousands of digital files from my scanning efforts to lightroom with no change or degradition of file names until this event.

What is more, when I look at the Orignal filename line in Metadata, all I see is the "untitled-(#)" and there is no "original Filename" so it was clearly improted using the "untitled (#)" file name.

Does anyone have any idea what might have happened and why?

Sure. You accidentally ticked the "Rename Files" box on the input screen.

I wqish it were that simple but the "Rename Files" function is not available when you select the "Add" function during Import. I shouold have mentioned that I first scan the files into windows explorer and then improt them to LR. So, that's not the explanations. Thanks, though....

Perhaps you selected "Copy" accidentally? According to Lightroom, are the photos in the same folder that they were in before import?

[Just Shoot Me]

What do you mean by "I first SCAN the files"?

Please post a screen shot of the Windows file manager window showing the names before import into LR and then after importing.

[Intermodalist]

They are in the same folders after Import as they were prior and I know that I did not use the copy function during Import. Since the files names were changed by LR during the Import process, it is  not possible to now show you the file names prior tgo Import.

According to Lightroom, or according to your operating system? I want to know where Lightroom thinks they are located.

OK how about copying some other images, shot with your camera or scanned on your scanner, to your hard drive and then importing them. You could then take a screen shot of them before the import and after the import. In fact you could leave the Windows file manager window open to watch what happens.

Also check in the import dialog that you have no Import Preset set near the bottom of the screen.
