How can I import Canon 7D photos after the file numbers wrap around?

My Canon 7D has wrapped its image numbering, so I now have newer photos with the same IMG_1234-style filenames as older shots. Picasa skips the newer files, and when I connect the camera by USB in Windows XP I only see one version of the duplicate filename. I don’t want to delete anything from the card because I’m keeping it as a backup while traveling. I also don’t currently have Canon EOS Utility installed or a card reader. What’s the best way to get all of the photos off the camera, including the newer files?

I can confirm that the EOS utility does import the duplicate files without any problems (and, as a side point, faster than Picasa too).
For some reason the EOS utility is not on Canon's website and my CD is a few thousand miles away.
Luckily I've found a workaround:
- Download EOS Utility updater from Canon's website
- Edit your registry (see below) to trick the updater into thinking you have already installed a version
- Run the updater.
I added the following registry entries for my system:
[HKEY_LOCAL_MACHINE\SOFTWARE\Canon\EOS Utility]
[HKEY_LOCAL_MACHINE\SOFTWARE\Canon\DPP]
[HKEY_LOCAL_MACHINE\SOFTWARE\Canon\ZoomBrowser EX]
[HKEY_LOCAL_MACHINE\SOFTWARE\Canon\PhotoStitch]
[HKEY_LOCAL_MACHINE\SOFTWARE\Canon\EOS Capture]
[HKEY_LOCAL_MACHINE\SOFTWARE\Canon\EOSViewerUtility]
For more info, see the site that helped me
If anyone has more info on the cause of my original problem or other solutions, I'd love to hear them.
Thanks, Matt

Generated from our catalog & community — verify before relying on it.
The files probably do not actually share the same full path. On Canon cameras, when the image number rolls past 9999, the camera usually starts a new folder inside the DCIM directory. FAT32 cannot store two files with the same name in one folder, so the duplicates are typically in different folders.
The issue is likely your import method, not the card itself. Two workable options were reported:
- Use a card reader. This gives direct access to the card’s DCIM folders, where you should see the rolled-over files in separate folders.
- Use Canon EOS Utility. It was confirmed to import these files correctly, unlike Picasa.
Why USB browsing from the camera may fail: the 7D does not behave like a simple USB mass-storage device, so Windows may not expose the full card structure when connected through the camera.
Best practical fix: get a CF card reader if possible, then copy from the card directly. Otherwise install EOS Utility and import through Canon’s software.
