Files with the .RAR extension contain data archives compressed with a proprietary algorithm. This format was developed in its initial version in the year 1993, by a Russian programmer – Eugene Roshal, and currently it is being developed along with the WinRAR software.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the TBZ file after converting to RAR may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from TBZ to RAR to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting TBZ to RAR does not meet your expectations, you can simply try to find on the Internet a different version of your file in TBZ format, properly converted to a RAR file by someone else. If this fails, use the information provided in the further part of the website.
Unfortunately, if after performing the two previously described steps (trying to find your TBZ file converted by someone else, and the attempt to convert it to RAR on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the TBZ file in its original format (without conversion to RAR file). Such a solution will be difficult to implement, but it certainly will give the best result.
