*IF* you have the actual files saved to a Windoze computer *AND IF* you haven't yet renamed the files copied to the computer, you could use Windiff to compare the files on the actual hard-drive to the files on the SD card.
From a command prompt: windiff [options] path1 [path2] or just: windiff ... and use the menus to choose files & directories to compare. On 10/9/2015 5:57 PM, Larry Colen wrote:
On my trip to Florida I shot a prodigious number of frames, even by my standards. I had nothing to do for a lot of that time apart from practicing photographing cars drive past very fast. Now that it is too late, I realize that I should not have deleted files off of the hard drives of bad images until I was certain that everything had been transferred to my home machine. Comparing the number of K-5 files in lightroom with the delta in the sequence numbers shows a difference of about 140 frames. I could just reformat my cards at this point and not worry about it. Since I don't think I actually deleted as many as 140, I can't help but wonder if maybe I just didn't copy over that one tremendous photo after a particular shooting session. Unfortunately, Lightroom's algorithm for checking if a file is already in the catalog does not work very well once things have been moved around. I cannot just put the SD cards in and trust that it will find those missing files. If, however, there were an easy way to go through a large number of files in a large directory tree, on a mac, and detect any large sequences of missing files (in the format of YYYYMMDD-LRCNNNNN.DNG (or .AVI) that would tell me right off the bat which files might be missing, and I could just look on the various cards for files in that sequence of numbers. Note that its the NNNNN that I'm interested in, I manually incremented the first number from 3 to 4 when the four digit counter looped. I doubt that I'm the first person to run into this issue, does anyone know of a lightroom plugin or shell script that will do the trick?
