Back to table of contents The RAR file is a compressed file, just like the original ARC and ZIP files a large file can be compressed down by more than half. The use of RAR files for home movies have become popular because the movie can be compressed and split up into smaller files. Programs Needed
The original WinRar files were named .rar to r04 if the files were split into 5 chunks
This shows the original file has been split into 4 chunks, in order to re-construct the original file, you will need WinRar and right click the "HomeMovie.rar" file to decompress. WinRAR will load Parts 1-4 automatically and re-create the original file. Compressing movies wont achieve much as they are already compressed using a compression codec, however splitting them into smaller chunks to send to your friends will help with slow download speeds. The New versions of WinRar will also let you make self extracting files, when these types are constructed the first file wont be HomeMovie.rar it will now be HomeMovie.exe then you wont need Winrar to extract the files.
In the above example I have a Testmovie.avi its size is 11.256Mb I have used WinRar to split it into 447K chunks, in the newer versions of WinRar the files are labelled Part01 to Part11, in this example Testmovie.part01.rar is the main file I would use to re-construct the original file. When you have re-constructed the file, it may be in another format other than video types. Some people make a copy of a movie disk they made and save the image to their hard drive, that image could be a BIN file, then the BIN file is split into chunks, so when they are re-constructed you may need to use some other program to get the AVI or Mpeg movie. It is not unknown for people to "Zip" up files with WinZip, then use WinRar to split them up, when reconstructing you may need to go though different stages to reach the desired file. HomeMoviePart1.avi HomeMoviePart2.avi Zip > Rar > 3 Rar files
Right Click Testmovie.part01.rar and select extract (WinRar) Right Click Testmovie.part01.zip and select extract (WinZip)
You now have the original files |
