R87 File Extension
Have a problem opening a .R87 file? We collect information about file formats and can explain what R87 files are. Additionally we recommend software suitable for opening or converting such files.
What is the .R87 file type?
Indexed filename extensions like .r87 belong to the Multi-Volume RAR/WinRAR Archive Part (.r00–.r99; .partNN.rar) file type. RAR is a proprietary lossless data compression algorithm and a cross-platform CLI tool by E.Roshal, its paid GUI version known as WinRAR (Microsoft Windows). Both RAR and WinRAR are capable of creating multi-volume, or split archives.
Every file within a split archive is designated with an indexed extension (like .r87), pointing out to its position within the ordered sequence. The extensions .r00 through .r99 are the "old" pattern, and the dual extensions .partNN.rar correspond to the "new" pattern adopted by default in recent WinRAR versions.
Thus, the .r87 file is the eighty-ninth part of a multi-volume RAR/WinRAR archive (the first part always has the .rar extension) named after the "old" pattern.
Archive files like .r87 are recognized and can be processed by all archive management tools that support RAR decompression (unrar). Although it may be possible to partially extract data from a standalone .r87 file, all preceding archive parts (.r86, .r85, etc.) are still required for complete data extraction.
