How to rename recovered .jpg files to original Canon names in windows 10?

gczerw · October 22, 2016, 05:01:15 PM

Using photorec, I have recovered a few thousand .jpg files that are in 5 directories. I have tried the following command, found on the "http://www.cgsecurity.org/wiki/After_Using_PhotoRec" page, to no avail!

The following command recreates the original directory layout and file names present on the card (for Canon cameras, tested with numerous photos from an EOS 20D), using the file number EXIF info. ExifTool works under both Windows and Linux.

exiftool -r '-FileName<IMG_${FileIndex}%c.%e' DIR

It uses FileIndex from EXIF information in file to rename to original filename, the %c is checking for duplicate names and appends other digit to the name. And it works recursively (-r).

As a test, I have placed one .jpg file in the "new" directory and have tried the following, with the result shown:

C:\Users\George\Downloads\testdisk-7.0\recover\new>exiftool "-FileName<IMG_${FileIndex}%c.%e" .
Warning: [minor] Tag 'FileIndex' not defined - ./IMG_102-0631.jpg
Warning: No writable tags set from ./IMG_102-0631.jpg

Can someone tell me what is wrong here? File information shown below.

exiftool -r '-FileName<IMG_${FileIndex}%c.%e' DIR

It uses FileIndex from EXIF information in file to rename to original filename

... but FileIndex was not available in the output you gave. There was a FileNumber tag though:

exiftool -r '-filename<IMG${FileNumber;s/.*-//}%c.%e' DIR

Here I have removed the directory number from the start of FileNumber using the advanced formatting expression s/.*-//

gczerw · October 22, 2016, 09:32:55 PM

Thanks for that, but I get the following:

C:\Users\George\Downloads\testdisk-7.0\recover\new>exiftool "-filename<IMG${FileNumber;s/.*-//}%c.%e" .
1 directories scanned
1 image files updated

However the file has neither been renamed or moved elsewhere....

Phil Harvey · October 23, 2016, 09:04:38 AM

something was updated. Add the -v3 option to get more details about what is happening.

I really don't understand why this is occurring....

Phil Harvey · October 23, 2016, 10:20:39 AM

This could happen if there were an invisible character (eg. a space) in the file extension. Otherwise, there is something funny that is wrong with your disk. I would try typing this:

rename "dead<tab> test.jpg

(press the tab key to complete the name, then rename the file to something you know)

- Phil

gczerw · October 23, 2016, 10:33:25 AM

Okay, that worked. Attached is the output of:

C:\Users\George\Downloads\testdisk-7.0\recover\new>exiftool -v3 test1.jpg >exif.txt

It is too long to paste...

Phil Harvey · October 24, 2016, 07:59:24 AM

I don't know why you posted the output of that command. I suggested adding -v3 to the command where you are trying to write FileName. But it seems the problem is that there were invisible characters in the file name so ExifTool didn't process it.

Sorry, I misunderstood...

File neither renamed nor moved anywhere!

Phil Harvey · October 24, 2016, 09:14:14 AM

I wonder if the "%" characters are causing a problem (although I am surprised that ExifTool didn't receive an error status when the rename failed). You only need the doubled "%" characters in the argument to -d or in a .BAT file. Try this:

exiftool -v3 "-filename<IMG${FileNumber;s/.*-//}%c.%e" .

gczerw · October 24, 2016, 09:43:56 AM

No luck...but clearly something is amuck here! Watch the sequence of events....

Out of curiosity, I just did a chkdsk of the drive. No errors found.

Phil Harvey · October 24, 2016, 11:30:03 AM

OK. That should have worked. I have never seen this specific problem before but try disabling your antivirus software to see if it is preventing ExifTool from renaming the file. Also, you may try a simpler command and try a different file. (eg. exiftool -filename=test2.txt test1.txt)

- Phil

gczerw · October 24, 2016, 04:50:55 PM

No change in behavior on Windows 10 desktop machine with antivirus shutdown.

However, out of curiousity, I took some files, went upstairs to the Windows 8.1 desktop machine and tried there... SOME PROGRESS!

Interesting that I'm getting results on the Windows 8.1 machine. The filenames were changed in the current directory. However but no appropriate Canon numbered directories were created and no files were moved.

Canon DCIM directory nomenclature is, for example 111_10, and filename nomenclature is IMG_xxxx.jpg. So how should I proceed to get those results?

Phil Harvey · October 24, 2016, 08:07:34 PM

Did you try turning off Windows Defender on the Windows 10 machine?

To also set the directory to ###_## as you described, you could do this:

exiftool "-filename<${FileNumber;tr/-/_/;$_=substr($_,0,6)}/IMG${FileNumber;s/.*-//}%c.%e" .

1. Defender was off on the Windows 10 machine.

2. That command did NOTHING on the Windows 8.1 machine (defender also off on it). But it says that it did!!! I can't find that new directory or file anywhere!
