OK, took the R7 (and the old 7DII as well) on a trip. In South Africa i took a slew of photos on game drives. I use the regular numbering system for files, but on one day things went just a bit strange.
OK, the usual system:
7M0A0001.jpg
7M0A0002.jpg
7M0A0003.jpg and so-on.
On one day, the files downloaded arrange themselves thusly:
Oh, and to make things even more confusing, the "0001.jpg" and the "0001_1.jpg" files were shot 13 minutes apart, and the _2 was an hour later than that. But the "0002.jpg" was shot in a burst with 0001.jpg.
What the heck button did I hit, or errant menu section did I hit to get that?
The day before had been normal, and the day after it went back to the normal numbering system.
aRGB files create the underscore at the beginning of the filename, e.g., instead of 7M0A the first 4 characters would be _M0A. I don't know about the other nomenclature but I never have used jpegs.
This was an interesting question and it rang a bell with me. The extended filenames are for images from a Burst Mode .CR3 file extracted using DPP. Interestingly, in my testing to confirm this, images extracted in-camera get incrementally increased file names as you would expect rather than the extended filenames.
In regards to your confusion about the arrangement of the downloaded files:
Depending on your settings for File Explorer/Finder, the default sequencing for the file names in the list is alphabetical, not time order. I suspect that if you sorted the file list by "date created", you'd get the two normally named files listed together with their respective create date/time, and the other groups of files listed in the time sequence in which you extracted them.
This wasn't an easy thing to find. I could find no reference in the R7 manual, the DPP manual, or an internet search that described the file naming convention for Burst Mode-extracted files. However, DPP does show the file name for the file when you save it as an individual file.
Caveat: there may be other specialized functions available in our new cameras that might also generate file names like this. I only looked at Burst Mode and Focus Stacking.
Interesting,and I wonder if that was a result of someones "bright idea" or a limitation in time and thus a shortcut needed to number files as they are being created?
I went into Zoombrowser (yes, I still use it, it works, I am familiar with it, and I use other software for any file manipulation) and went into View, Sort by, and selected Shooting Date.
