Why Can iPhone Not Open RAR Files Natively?
iOS includes native ZIP support through the Files app, but Apple does not bundle RAR decompression. RAR is a proprietary format that requires a licensed decompression engine. The Files app displays RAR files as generic documents with no option to preview or extract their contents. Tapping a .rar file in Files shows an "Unable to open" error. UnFox solves this by bundling a RAR decompression engine built on libarchive.
How Do You Extract RAR Files on iPhone Step by Step?
Open UnFox and tap the file picker button on the Extract tab. Navigate to the RAR file in the Files app interface and select it. UnFox reads the archive and shows the extraction progress with file count and percentage. Once complete, tap "Show in Files" to view the extracted folder, or tap any file for a QuickLook preview. For RAR attachments in Mail or Messages, use the share sheet and select UnFox to extract without saving to Files first.
