Sorting Photorec results

Hi all,

Is there a quick and easy way of sorting the results of files recovered by Photorec? I'm only after a few types of files from the 30+ folders of 500+ files per folder? Ideally I'd like each file type in a different folder.

Is that fairly simple to achieve? I'm hoping a bash script somehow?

Thanks

For those of us that don't have Photorec but may be able to help, it would be helpful if you posted a short illustrative sample of the Photorec output you want to sort -- or a full output somewhere like pastebin

Hi, a sample should get the point of how it sorts it.

So photorec uses some sort of black magic to recover 'deleted' files, or in my case a SD Card with no partition table. It recovers them into folder like this:

Code:

$ pwd

/home/user/Photorec



$ ls

recup_dir.1   recup_dir.17  recup_dir.24  recup_dir.31  recup_dir.4

recup_dir.10  recup_dir.18  recup_dir.25  recup_dir.32  recup_dir.5

recup_dir.11  recup_dir.19  recup_dir.26  recup_dir.33  recup_dir.6

recup_dir.12  recup_dir.2   recup_dir.27  recup_dir.34  recup_dir.7

recup_dir.13  recup_dir.20  recup_dir.28  recup_dir.35  recup_dir.8

recup_dir.14  recup_dir.21  recup_dir.29  recup_dir.36  recup_dir.9

recup_dir.15  recup_dir.22  recup_dir.3   recup_dir.37

recup_dir.16  recup_dir.23  recup_dir.30  recup_dir.38

In each of the folders, you have a list of files:

So in recup_dir.38 a short selection of files using "ls" is:

Code:

f21331411.txt  f21357080.txt  f21375205.txt  f21380160.jpg  f23113738.java

f21331416.txt  f21358016.jpg  f21375210.txt  f21380224.jpg  f23113740.java

f21331502.txt  f21358111.txt  f21375215.txt  f21380352.jpg  f23114929.java

f21331584.txt  f21358120.txt  f21375220.txt  f21380480.jpg  f23114930.java

f21331925.txt  f21358154.txt  f21375264.txt  f21380544.jpg  f23114932.java

f21331968.jpg  f21358391.txt  f21375808.txt  f21380608.jpg  f23114933.java

f21332096.jpg  f21358399.txt  f21376003.txt  f21380672.jpg  f23114934.java

f21332160.jpg  f21358774.txt  f21376005.txt  f21380736.jpg  f24059928.ini

f21333300.txt  f21358786.txt  f21376007.txt  f21380864.jpg  t21327872.jpg

f21333303.txt  f21358796.txt  f21376015.txt  f21380928.jpg  t21328832.jpg

That's the smallest directory by 200 items, containing 331.

I hope that clarifies my problem a little bit, apologies if it's a little too simple or not complicated enough. I'm not great with computers so it's hard to know what's common knowledge and what's not, I hope I haven't seemed patronising.

* If you are certain your SD cards contained only image files with certain extensions then I would backup the results and rerun Photorec with only those specific image file filters enabled.
* For sorting see http://www.cgsecurity.org/wiki/After_Using_PhotoRec

Note the script below looks only at the string after the last dot and it will create directories like /home/user/Photorec/txt, /home/user/Photorec/jpg, etc, etc:

Code:

cd /home/user/Photorec

find /home/user/Photorec/recup_dir*/ -type f | while read ITEM; do

 TARGET=${ITEM//*./}; if [ ! -d "/home/user/Photorec/${TARGET}" ]; then

  mkdir "/home/user/Photorec/${TARGET}"; fi

 mv "${ITEM}" "/home/user/Photorec/${TARGET}"

done

Fantastic, thank you very much for the link and the script.

Unfortunately, I wasn't 100% sure that my photos would not be saved as .jpg, .JPG, .JPEG etc so that's why I just recovered everything. Now I've reused the card I can't re-photorec it, but they're not sorted into a manageable order.

Thanks again :)

For next time remember to make a bit-by-bit copy of the victim drive. That way you have a backup to work on leaving the original intact.

Yes, because once deleted there is no longer any order. BTW if your images contain EXIF data you may be able to at least order them according to image creation time:

Code:

cd /home/user/Photorec

find /home/user/Photorec/recup_dir*/ -type f | while read ITEM; do

 file "${ITEM}" 2>&1|egrep -q "(JPEG|JFIF)" && \

  { RES=($(exiftime "${ITEM}" 2>/dev/null)); [ ${#RES[@]} -eq 4 ] && echo "${ITEM} ${RES[2]} ${RES[3]}"; }

done

Sorry, that was a typo. Not was mean to read now. I can manage to go through the photos and arrange them properly.

Thanks :)
