File Viewer for Android vs HFSExplorer

File Viewer for Android combines a file viewer and file manager, opening more than 200 file types on Android devices. It covers PDFs, Office documents, eBooks, email files, audio and video, images, camera raw files, and archives. Its tools can convert documents to PDF, extract archives, view and install APKs, display metadata and checksums, and show source code with syntax highlighting. The file explorer browses, searches, and manages files on device storage and SD cards. FileInfo.com integration can show a file’s type, popularity, category, and developer. Files are opened locally rather than sent over the Internet for processing or rendering. The app is free and ad-supported; an optional Pro in-app purchase offers an ad-free experience and additional features, with no price listed. It requires Android 9.0 or later. It does not support every file type, and eBooks must be non-DRM protected. Sharpened Productions, based in Minneapolis, says it was founded in 2003.

HFSExplorer is a free, read-only desktop program for browsing Mac-formatted hard disks and disk images on Linux, macOS, and Windows. It supports HFS, HFS+, and HFSX file systems. Its graphical browser can show volume information and extract files, and the program can create disk images. It reads most Mac.dmg and.sparsebundle images, including zlib- or bzip2-compressed images and AES-128- or AES-256-encrypted images. Supported partition schemes are Master Boot Record, GUID Partition Table, and Apple Partition Map. The listed price is free, and the software is released under GPL version 3 with no warranties. HFSExplorer requires Java SE Runtime Environment version 5.0 or later; its page says OpenJDK works. Accessing physical disks requires administrator or equivalent privileges. The page also describes a separate minimal text-mode program as unmaintained and limited to HFS+. Bug reports and discussion are directed to GitHub. The listed latest version is 2026.4.9, dated April 9, 2026.
