WinRAR is a data compression and decompression utility that lets you access and search archive files. Although many compressed archives contain only a handful of files, some archives contain many hundreds of thousands of files, requiring a search to locate files within them. WinRAR's search feature lets you quickly locate specific files with a search term across your entire hard drive.
