Problems do arise if the password of an archive is not known (anymore). One could try and enter possible combinations manually which could take years to complete or use a rar password cracker to speed up the process of discovering the right rar password.

Possible scenarios are that you forgot the password of a previously created rar archive or that a former employee protected files with a rar password. Whatever it is the rar password cracker will aid the user. The tool utilizes password lists, also called dictionary files, to test against the rar password.

Rar Pass Finder is a portable lightweight tool. The interface is only available in German language but since it consists of only two buttons it does not really make a different. The user should start loading a rar password list using the Passwortliste button.

Rar archives can then be loaded using the Rar-Archiv button or drag and drop. The rar password cracker supports multiple volumes and can also be run from the command line to load an archive automatically into the application. The last loaded password list will automatically be used to find the rar password.

They are providing their readers with a free license key to Winrar 3.62 which can be used with the German and English edition of Winrar. Winrar 3.62 is obviously not the latest version of Winrar, that would be 3.71 by the way, but it is sufficient for all your unpacking needs.

Interested users can also use the offer to update to the newest version of Winrar at a discount. If you are interested in the offer visit the promotional Winrar website. The website is written in German, all you need to to is fill out the form and the license key will be send to your email. Here is the translation of the fields: Vorname (First Name), Nachname (Last Name), E-Mail-Adresse (E-Mail), E-Mail bestätigen: (E-Mail again) and Land (Country).

Select Anderes Land in the pulldown menu if you are not living in one of the mentioned countries. A click on Abschicken (send) completes the process and you should receive a link to the key in your email. The link to the key is the second link in the email that contains download.php while the first link would lead to the special offer page that would offer a discount for the latest Winrar version.

A click on “Download des Lizenzschlüssels” downloads the key to your computer. Download Winrar 3.62, for example from Download Junction and install it on your system. Now unpack the contents of the archive that you have downloaded into the Winrar folder. The key will be automatically recognized by Winrar and you got a licensed version.

Each of the 24 files began with x.rar and ended at x.r24 with x being a number between 1 and 24. I did not want to right-click all 24 files one by one and select Extract Here from the menu because this meant a lot of work. I had to stay at the computer all the time as well to initiate the next process.

I knew that it was possible to mark more than one file and extract it at once using the right-click menu function but I did not know how to handle archives with multiple volumes. The obvious way to handle those files would be to mark them all and extract them but this did not work because only the first volume of an archive has to be selected to unpack it.

My first test brought the correct result though. I marked all the 24 rar files (change that to zip or whatever format you are dealing with) and right-clicked one of them. I then selected Extract Here like I would when extracting single archives and all the 24 rar files where extracted at once.

This is in my opinion a great time saver and will hopefully help at least some users who were facing the same problem.

In short, they can be used to repair any rar file that is part of the archive as long as the blocks of the par file are at least of the same size than the corrupt rar parts. A software like Quickpar can be used to split big files into smaller ones and create several par files to be able to recover the whole archive if part of it gets corrupted.

To use Quickpar you simply add one or more files that you want to split into parts, select a file size for those parts and the amount of Recovery blocks that can be used to recover the archive if files do get corrupted.This is excellent if you want to backup important files, videos or pictures on CD or DVD.

We all know that sometimes those CDs and DVDs become partly unreadable and the created pars can be used to recover the complete archive even though part of it could not be read.

It is possible to alter several other settings before splitting the big file and creating the pars but that is normally not necessary. You could raise the block size for instance. The user could also keep the original file and create pars for it to be able to recover it if put on CD or DVD or transferred over the Internet.

Files can be recovered by clicking on any par file that is created in the process. Quickpar will automatically load the archive and check all files within to see if any are corrupted. If they are it tries to repair those corrupt blocks automatically if enough par blocks exist.

The rar files should be in the same directory for this method. Just mark all rar files, right-click the marked area and select to uninstall all files in this location.

The name of the command is different depending on the application that you use to unrar files normally. My packer IZArc has its own entry in the right-click menu and I can select Extract Here from the personal menu to extract all rar files that I have selected.

It took a while until I stumbled upon this method. Before that I really extracted every rar file on its own which takes a while if you have dozens of independent rar files on your computer. I thought I share this method even though I might be the last person on earth that found it.
