Sony Camera Losing File Extensions

[mindless1]

I have an old Sony DSC-HX10V camera. Since new.

It seems to work fine, except for one thing. Pictures taken, the files lose the JPG extension if renamed, but not right when I rename it.

For example if a file on the SD card is named DSC00800.JPG, and I rename it something more appropriate like Clock.JPG, put the SD card back in the camera, then the next time (or might take a few times) I use the camera, then look at the filenames, it has removed the .JPG extension from the Clock.JPG so it is now just "Clock" of file type "File" (generic with no extension).

The file is not corrupted, I can rename and put the JPG extension back on and it works. I have lost no files, they're all there so does not look like general filesystem corruption per se. Files that still have the original name the camera gave them, do not lose their JPG filename extenson.

I don't know of any camera setting that is the equivalent of "don't do that", anyone know what's going on or how to make it stop doing this?

So, I tested it out on my A7III and the same thing seems to happen.

I will recommend not renaming files though since it can turn into a mess if you ever wanted to do a batch dump into a single folder since you'd run into same name conflicts. With JPEGs you can easily view them on almost any device without plugins, programs or applications. I think you should consider specifically named folders on the PC/Phone/Tablet instead of changing file names.

Woodchuck_1, Woodchuck_2, Woodchuck_3..._40000. I used to do it and I have a folder with all the dumped files that needed to have random endings since I shot loads of similar things and gave them similar names. Sigh.

Thanks gradoman.

I can deal with it, just wondering if there's some alternate angle to stop it from messing with files already established.

Camera automatically going in and changing a filename already there seems like a cardinal sin to me.

I don't remember when/where I heard this, but I don't edit/delete files directly on the card itself (I always take the card out, download the files and then format the card in the camera. Rinse and repeat)...not sure if it was an old wives tale or not about that affecting the longevity of the card's life or something...

Edit: I do remember something about minimizing the "writes" to the card so offloading the files to your PC just became a habit for me...probably in the grand scheme of things, changing file names won't have that big of an impact over the life of the card, but it just seems more risky to keep your files on the card and not your hard drive....

^ I've used the same 32GB SD card for the life of the camera, 7+ years now, never formatted besides the first time i put it in just to make sure the camera liked it.

I usually do move the files off but every now and then I just leave them there. Since I seldom shoot video with it, there's still enough free space for 4000+ pics.

Are you actively editing JPG files on the card (renaming files or making changes to the actual image like cropping, etc) and then saving them back to the SD card?

^ I was just renaming to something more appropriate but I doubt it would matter if I was editing the image too.

Clearly someone at Sony went on a power trip while oblivious to basic, sound, data practices. Any OS that sees a file and changes it on a whim (with the possible exception of anti-malware software) is defective.

There is no useful purpose for the camera doing that. If there were, I'd recognize a trade off was being made.
