Any way of more than 4 digit file no.

Hi all.
I have a 550 D, 60 D, and soon a 6 D. On both existing cameras I went at least ones around the clock AKA started back at IMG 0001.
My question is there a software or setting that allows me to have a 5 digit file number.
I use LR5.2 as my picture download program but would not mind to use a different software to get the files onto my laptop and than into the LR catalog.
As far as I could find out there is no in camera way to alter the file sequence in the 3 cameras mentioned.
Any help welcome
Guido

I use a renamer program when I get past 9999. I had one issue when my 7D decided to go back in time a few thousand clicks when it was at around 11,000 and it's only recently I have gone back in front of the original shuter count. I still have no idea what happened there, but do remember loading an old card in that had old shutter number images on it, but I don't really know. My numbering system is a bit of a mess now because of that.

But I agree, it's a major pain, especially in todays world. Back in DOS days I could understand it, as if you look at the filename there is 8 characters, which coincidently used to be the same limitations of PC filenames back in the day. Windows nowdays will handle a small story written in a filename of course. If there is one thing I'd like to see implemented in new camera firmware it's this, but if they haven't done it by now, I'm not going to hold my breath

The one I use is D-FileMU http://www.softpedia.c​om …Management/D-FileMU.shtml
Can be a little tricky to understand the userface at first but I find it works well. I use it to simply add a #1 in front of the number or to turn IMG_3578 into IMG_13568. It deals with batches as well of course. There may be better out there now, so if anyone has anymore, feel free to share as I'm always open to change.

I rename on import to Lightroom 5.3 Library -> Import -> Check Rename Files under File Renaming on the right hand panel. Create a template to use and you're good to go

Use directories?

The number in the file is an Exif specification, which Canon follows. Best advice: Don't use the number as a reference! The supplied EOS Utilities software can also rename images on transfer to the computer. You can mix in the folder number and camera type, to make sure you don't get a conflict between files with the same number from different cameras. Storing images in folders with names like 2014_01_13 will also help.

Yup, use something like ImageIngester, Downloader Pro or the LR import options to customize the file names as they're transferred to the computer. You can get your images atomatically saved to folders determined by camera type, serial number, year, month, date with filenames just as easily configured so that you'll never need for that 4-digit numbers.
