Curious about the "2V2A" prefix in my 7DmII photo numbering, can this be removed?

I've recently discovered that four digits just isn't enough for me to have easily definable photos, so if I have "2V2A7193.JPG" there's a good chance another identically named file is hanging around within a month or two. I'd love to ditch the 2V2A and just have sequential numbering that goes for another 4 decimal places. Is that possible? I saw I can opt for "IMG_" in the settings but it didn't appear I could get rid of this completely.

Any help would be wonderful, thank you in advance!

Use the free Canon DPP4 software to rename the files.

Thanks for the suggestion but I'm running Linux, this tool doesn't work for me, but more importantly, I'd like the camera to have more than 4 usable digits in the name. That's the real question. If it only goes to an effective 9999 before switching over again to 0000 that seems a waste of 4 digits in the filename. Just hoping I could get it to name up to 99999999 before returning to zero.

All digital cameras use the DCIM file format which is a four character alpha-numeric prefix and a four digit file number, as well as the eight-dot-three general file name format. That's why the file name includes JPG, TIF, CR2. Your options are the camera-unique 2V2A prefix or IMG_.

I am sure there are file renaming tools for Linux.

Your Card is divided into subdirectories that only hold 1000 files, which set the index number:

Thanks, this is what I was looking for. Seems arbitrary and silly to have identically named images in a single photoshoot, but that's a different issue. Seems 9999 is the best one can do at the current time. (And yes, there are file renaming tools for Linux. That part's easy.)
