A .rar file is not a media file. It is a compressed archive. The archive itself may well contain one or more media files within it, but you must decompress the file to open them. In order to decompress a .rar file, you need a utility like WinRAR to open it.

Badly, there is no way. You should decompress to ISO and then Extract. You can use PSP ISO COMPRESSOR to decompress it!
PHP isn't generally a compressed file, so it all depends on what format it was compressed into. Hope this has helped, Cpl.Vadera
By decompressing it. There are plenty of online tools that let you do it. You can also download programs to unarchive/decompress it for you.
When using lossless compression (such as putting the file in a Zip or RAR archive), there are no permanent consequences; the file can be restored to its full uncompressed form at any time. The only factor is the additional time and space it takes to compress and decompress the file.
The disadvantage of multiple file compression is that you need to decompress everything, even if you only need one file.
It depends how it was compressed Any files I compress I can decompress by simply right-clicking and selecting 'Extract all'
Typically a gz file extension is an ARCHIVE. That means it might have ONE file in it or MANY files in one file that is COMPRESSED. You have to decompress the file (or de-archive it) and then you can open the file or files and do whatever you need to...then you can RE-archive the file. There are many archive file formats. ZIP...RAR...GZ. GZ is typically used on Unix/Linux systems.
A RAR file is a compressed archive file, similar to a ZIP file. So, you need software that will unpack or decompress the files. Search the Internet for 7Zip. That's a program that will open numerous types of compressed archive including ZIP and RAR. It's free, too.
