NOW for the stolen PAR2 tutorial

INSTALLING

PAR version 2.0 (PAR2) is the more efficient successor of PAR (PAR1). You can use PAR2 to check whether your downloaded files were received completely and correctly and you can repair any missing or corrupt files if necessary! PAR2 divides a RAR-set into ‘blocks’ so that the downloader can see how many blocks are missing. After that he can download that number of PAR2-blocks for reparation.

This tutorial is written for QuickPar, version 0.91.

Configuring QuickPar

After installing, open QuickPar and click ‘Options’.

A. Integration.

Here you can choose to use QuickPar for PAR2, PAR(1) and SFV files. In the past you had to use several other programs for these file types but today QuickPar can read them all. The option ‘Integrate QuickPar into Shell’ adds QuickPar to the context menu of the Explorer, which can be very easy.

B. Preferred Block size.

This is an important setting if you want to create PAR2 files. Here you need to enter the number of ‘lines’ you use when posting. This number can be found in the configuration of PowerPost, where 5000 lines is the default setting. If you only use QuickPar to verify and repair files, you can leave this setting unchanged.

C. Default Verification and Repair Options.

By activating ‘Monitor Automatically’ QuickPar will keep watching the download directory while your newsreader is still downloading, so downloaded files will directly be verified by QuickPar. If you also select ‘Repair Automatically’ QuickPar will start repairing the set (if necessary) as soon as enough PAR2 repair blocks are available.

D. File Deletion.

You can let QuickPar automatically remove damaged files and PAR2 files after a successful reparation. I only use the first option because the PAR2 files still might be handy afterwards (for example to create extra PAR2 files to help other downloaders).

E. Default Priority.

Here you can assign the priority that QuickPar gets compared to other programs. The fastest recovery can be achieved by choosing ‘High’, but obviously that causes other programs to be very slow while QuickPar is busy repairing.

F. Other settings

When ‘Quiet operation’ is activated, QuickPar will not let you hear a sound when it is done verifying of repairing.

Press ‘OK’ to save the settings and to close the Options window.

USING

To use QuickPar to verify or repair data files, you should either double click (or right click and choose "Open with QuickPar") a PAR2 file in Windows Explorer, or start QuickPar and click "Open".

QuickPar will immediatly start analysing the PAR2 files and verifying the files that they protect. You will see the following window:

You will see in the above screenshot that all of the data files are complete and that the PAR2 files contain the correct number of recovery blocks.

At this point you can Click "Clear" and then "Open" to open another PAR2 file, "New" to create new PAR2 files, or "Exit" to exit from QuickPar.

Repairing damaged files

If the data files are damaged, then QuickPar will display the following:

The information displayed shows that 33 of the 35 files are damaged and that the repair will require 96 blocks of recovery data.

At this point you can have QuickPar load additional PAR2 files (to provide more recovery blocks) or scan additional data files (to see if they contain some of the data from the original files). To do this click the "Add" button and select the additional files.

You can also select the "Monitor" checkbox and QuickPar will automatically scan new files as soon as they appear (e.g. if you need to obtain more files from UseNet).

The screenshot below shows the results after some PAR2 files have been obtained and loaded:

You will see that two PAR2 files have been obtained with a combined total of 113 recovery blocks and the QuickPar now indicates that repair is possible (using 96 of the available recovery blocks). You should click the "Repair" button to start the repair.

When you start the repair, all of the damaged files will be renamed (with a ".1" file extension). Once the repair has been completed, QuickPar will automaticaly verify the repaired files:
