## Introduction

Here describes about how you can restore normal names for the most of a recovered tar.gz archives by photorec. First you need to create a file with a more detailed information about files, see: post recovery tasks. Restored tar.gz files with photorec might look like `./recup_dir.996/f864593944_wmmaiload-1.0.5.tar.gz` or `./recup_dir.996/f864589184.tar.gz`.

The tar.gz archive includes inside a tar archive whose name is used to restore filename of the tar.gz if it is possible or name of a first folder/file from inside of the archive.

The ways that might be used to restore the name of the tar.gz archives:

- From part of a name by cutting everything before '_' in files with created by photorec with pattern: f864593944_wmmaiload-1.0.5.tar.gz
- From name of a tar inside of the tar.gz archive.
- From the name of the folder inside it. In many cases it usually compressed a whole folder that might be similar to the archive name.

Note: This script restores only by separating original name from the photorec generated name or use a name of the first folder or file inside of the archive.
To restore all of the files that contain only the original name as part of the generated you can download the restore-orignames-only.sh script from the SourceForge website, but it will add the Duplicate123 (123 is number of a processed file) to files with the same name in the destination directory.

## Collect info data about tar.gz

Collecting needed data from inside of the archives in order to restore their names.

    collect-info-about-tar-gz.sh

    #!/bin/bash

    FileName="$1"
    IntCheck=$(7z t "$1" | grep ^"Everything is Ok"$ )
    AddIt="False"

    if [ 'XX'"$IntCheck" != 'XXEverything is Ok'   ]; then ErrorFlag="Damaged";else ErrorFlag='OK';fi;

    if [ 'XX'"$(echo "$FileName" | grep -i tar.gz$ )" != 'XX'  ];then
    AddIt='True'

    BaseFileName=$(tar -tvf "$FileName" | head -1 | awk '{ print substr($0, index($0,$6)) }' )
    OutOfOrig="$( echo "$1" | awk '{ print substr($0, index($0,$4)) }' )"
    if [ 'XX'"$(echo "${BaseFileName}" | grep '/')" == 'XX' ]; then

    BaseFileName="$(echo "${BaseFileName}"|  sed 's/\///m')"
    fi
    fi

    if [ $AddIt == 'True'  ]; then

    if [ 'XX'"${OutOfOrig}" != 'XX'   ]; then IfOrig=$(echo "$OutOfOrig" | grep -v '/') ;fi
    if [ 'XX'"${IfOrig}" != 'XX'   ]; then BaseFileName="$IfOrig" ; fi
    BF="$(echo "$BaseFileName" | sed 's/\///g' | sed 's/^\.//m' )"
    echo "$1"'|'"${BF}"'.tar.gz''|'Errors:'|'$ErrorFlag'|' >> /tmp/tmpDB.txt
    fi;

Run `find -type f -name *.tar.gz -exec collect-info-about-tar-gz.sh "{}"\;`

## Restore filenames

This will restore file names based on collected ínfo about files.

    restore-tar-gz-names.sh

    #!/bin/bash
    CountAll=0

    Destination="$HOME/tar-gz"
    mkdir -v "$(echo $Destination)" -p

      ArrayFillCount=0;
    while read line ; do
      ArrayFillCount=$((ArrayFillCount+1))
          ArrayOfFiles[$ArrayFillCount]=$line
    done < /tmp/tmpDB.txt;

    XX=${#ArrayOfFiles[@]}
    echo $XX
    while [  $XX != $CountAll ] ; do
    FolderName="$(echo ${ArrayOfFiles[$CountAll]} | awk -F'|' '{print $2}' | cut -c1-4 | tr '[:lower:]'  '[:upper:]' )"
    PathToFile="$(echo ${ArrayOfFiles[$CountAll]} | awk -F'|' '{print $1}')"
      FileName="$(echo ${ArrayOfFiles[$CountAll]} | awk -F'|' '{print $2}')"
    #SourceFolder="$(echo $PathToFile | sed s/$(basename $PathToFile)//m )"
     SourceFolder='./Sorted/'

    if [  "$(echo $FolderName)" ==  '.TAR'  ];then
       FileName="$(echo ${ArrayOfFiles[$CountAll]} | awk -F'_' '{ print substr($0, index($0,$4))}'|awk -F'|' '{print $1}' )"
       FolderName="$(echo $FileName | cut -c1-4 | tr '[:lower:]'  '[:upper:]' )"
    fi
    if [ -f "$FileName" ]; then
         FIX="$(echo $PathToFile | sed s/$(basename $PathToFile)//m )"
         BadName="$(echo $PathToFile | awk -F"$FIX" '{print $2}' )"
         if [ -d "${Destination}/BadName"  ];then echo A > /dev/null;else mkdir "${Destination}/BadName";fi
         cp -fv "${PathToFile}" "${Destination}"'/'BadName'/'"$BadName"
    else
      IfExist="$(echo $Destination/${SourceFolder}${FolderName})"
      if [ -d "$IfExist"  ]; then echo a > /dev/null;else mkdir -vp "$(echo $Destination/${SourceFolder}${FolderName})"; fi
         if [ -f "$Destination/${SourceFolder}${FolderName}"'/'"$FileName"   ];
         then DupName="${FileName}"_Duplicate"${CountAll}";
    IfExist="$(echo $Destination/Duples)"
    if [ -d "$IfExist"  ]; then echo a > /dev/null;
    cp -fv "${PathToFile}" "$Destination/Duples"'/'"$DupName";
    else
    mkdir -vp "$(echo $Destination/Duples)";
    cp -fv "${PathToFile}" "$Destination/Duples"'/'"$DupName";fi
      else
    cp -fv "${PathToFile}" "$Destination/${SourceFolder}${FolderName}"'/'"$FileName"
      fi

    fi
    CountAll=$((CountAll+1))
    echo $CountAll
    done;
    echo $XX

Files will be restored with pattern like `$HOME/tar-gz/Sorted/MIXE` where MIXE is the first 4 letters of a filename. You can adjust it with the `cut -c1-4` command inside the script. In the `$HOME/tar-gz/BadName` places damaged files or files where it was impossible to get filename. In the `$HOME/tar-gz/Duples` places duplicates of files with pattern filename.tar.gz_Duplicate123 where 123 is a number of a processed file.
