Reading text posts and downloading binary files


You will find both text and binary posts in binary groups. In binary groups, text posts are often comments on binary files that have been posted or requests for certain files. To read text posts is very simple. Select a text post in Newsbin Pro and either hit CTRL + R, or right click on the post and click Read Post Body.

Notepad will now launch allowing you to read the text posted.


Downloading binary files from groups

Downloading binary files could not be easier -> simply double click any you want to download and they will appear in the Download list. Alternatively, you can select many of them at once, right click and select a Download option. Depending on your personal settings, when you download from Newsgroups directly (not with NZB files or anything) they may appear in a folder named after the Newsgroup. For example, downloading a file using an NZB file (we learn about NZB later) will put it in my default download directory which is...

C:\Downloads\

However, if I download a file directly from alt.binaries.multimedia inside Newsbin Pro, depending on my settings it may download to...

C:\ Downloads\alt.binaries.multimedia

Later I will show you how to turn off this feature if you find it annoying. Your download speed depends on your overall Internet connection speed, the quality of your Usenet provider and the number of concurrent connections you are allowed to have (download speed will be affected by other processes using the Internet. Using BitTorrent or something at the same time as downloading from Usenet is not recommended).

OK, so now you know how to get a Group List, Add a group to your personal list, download headers from it and view them, read text posts and download binary files. Next we ask the question, What kind of files do you find most frequently in Newsgroups?


Common file types in binary groups

Generally, the files you find in a binary group depend on the group itself. Look at the simple picture that accompanies this text; in alt.binaries.multimedia, you commonly find RAR files. In alt.binaries.sounds.mp3, you commonly find MP3 or other music files. In alt.binaries.e-book.technical, you commonly find PDF or DOC files.

This part of the guide will cover some of the basic types of files you will find on Usenet.


Pictures -> JPG, GIF, BMP etc.

Everybody is familiar with the common image files. The most common type of files on Usenet are pictures of all sorts. Picture viewers are generally provided with your operating system so there is not a lot to be said about these.

E-books -> PDF, DOC, DJVU etc.

There are a lot of E-book groups to trade all sorts of material such as technical books, magazines, newspapers etc. There is no shortage. The most common format is PDF. In order to view PDF files you need to get Adobe Acrobat Reader which is free. DOC files can be opened with Microsoft Word or OpenOffice.org. For DJVU documents, look here.

Compressed / Split RAR files -> PART1.RAR, PART2.RAR or .R01, .R02, .R03 etc.

Compressed RAR archives are one of the most popular types of files you will find on Usenet. Because of file corruption and completion rates, it makes sense to post very large files in split parts and extract later on. You will either get files that are named like those in the picture with this text or you will get one .rar file with many .r01, .r02, .r03 etc. files.

You need to download and install WinRAR. If you have a set of files like those in the picture above, then the one you need to open will have part1.rar at the end of it. If you have one .rar files and many .r01, .r02, .r03 etc. files, then you need to open the .rar file. If you get errors opening, you have experienced file corruption problems that are associated with Usenet, close them and go forward to the next page of this guide, "Corruption, introducing PAR, PAR2" and then come back. Either way, open the relevant file when you can.

You will now see the file(s) that are compressed inside this set of RAR archives. In this example, I have one file, video.avi, which is 243MB split into 17 different files of 14.3MB each (except for the last). In order to get that file out and play it, I can either drag it and drop it onto a windows folder or windows explorer, or select it and click Extract To.


When you click Extract To, a new window will open. This allows you to set a destination to extract your file(s) to. A notable feature here is "Keep Broken Files". If you try to drag a file from a corrupt set of archives out of WinRAR, you will just get an error and no file. However, if you select "Keep Broken Files" here and extract this way, WinRAR will extract as much of the file as possible for you.

When you have selected a destination to extract to, click OK.


WinRAR will now begin building the file from all the RAR archives. The time this process will take depends on the speed of your computer and just how large the file(s) to be extracted are. For future reference, if you right click RAR files in explorer, it will give you extraction options, which is a faster way to extract files from RAR files.

However, WinRAR cannot handle all sets of files you will find.


Split files -> .000, .001, .002, .003, .004, .005 etc.

You will often find files posted with file names like those seen in the picture beside this text. Files like these are simply split into several parts. In the example, a 243MB file (video.avi) is split into 16 different parts. WinRAR will not open these files for you. Instead, you need to download and open HJSplit.


HJSplit is a very useful freeware tool that can split files into smaller parts which is better for Usenet posting, can join them, compare two files and run a Checksum check on a file. If you have found files on Usenet will extensions like .001, .002, .003, .004, .005 etc., then HJSplit is definitely what you need to use.

Click Join.


When the join window opens, click Input. Browse for the file you want to join. By default, HJSplit will only show you files with .001. When you locate the file, select it and click Open. You now have an option to also select an output director if you wish. When you are ready, click Start.


HJSplit will now start working on the joining process. The amount of time this takes depends on the speed of your computer, how much resources are available and of course, the size of the files to be joined.


Parity Files -> PAR, PAR2

These files are used for the recovery of corrupt files or corrupt blocks of files (PAR2). In the next page, we will see their significance.
