To open a compressed file, you will need a tool to properly extract or decompress the file. Depending on the type of file, there are several different tools available to do this.
Zip Files: Zip files are the most common type of compressed file. To open a zip file, you can use a software program such as WinZip, WinRAR, 7-Zip, or PeaZip. All of these programs are free and allow you to extract the contents of a zip file. To use any of these programs, simply download and install the software, and then locate the zip file you want to open. When you locate the zip file, highlight it and click the Extract button. This will open up a window that will show you the contents of the file. From there, you can decide where to save the extracted files.
RAR Files: RAR files are similar to zip files but they are more efficient, meaning they can be up to 30% smaller than a zip file of the same contents. To open a RAR file, the best option is to use WinRAR, an advanced file compression utility. To use WinRAR, simply download and install the program and then locate the RAR file. When you locate the file, double-click it and it should open up in the WinRAR program. The program will then show you the contents of the file and you can decide where to save the extracted files.
7z Files: 7z files are very similar to zip and RAR files, and like these two types of files, 7z files can also be compressed to reduce their size. To open a 7z file, the best option is to use 7-Zip, a popular archiving program. To use 7-Zip, you first need to download and install the program, and then locate the 7z file. When you have located the 7z file, right-click on it and select Extract Here. This should open a window that will show you the contents of the file and you can decide where to save the extracted files.
Jar Files: Jar files are often used to package Java applications and applets. To open a jar file, you can use a program called Java Archive (JAR) Opener, which is a free program. To use JAR Opener, download and install the program, and then locate the jar file you want to open. When you locate the file, double-click it and this will open up a window that will show you the contents of the file. From there, you can decide where to save the extracted files.
ISO Files: ISO files are usually used to store large files such as games, movies, and software programs. To open an ISO file, you can use a program such as WinRAR, 7-Zip, or MagicISO. All of these programs allow you to extract the contents of an ISO file. To use any of these programs, simply download and install the software, and then locate the ISO file you want to open. When you locate the file, highlight it and click the Extract button. This will open up a window that will show you the contents of the file and you can decide where to save the extracted files.
