Files v0.1.15

• macOS: a click on the Dock icon brings Files back when its window was closed (a new window opens) or minimized; folders sent from the system or a second start open a window again too.
• Preview shows everything a file says about itself. Photos: size, megapixels and shape, format, color space, orientation; camera, lens, software, date taken, author; aperture, shutter, ISO, focal length, exposure, flash, white balance; GPS location. Video and audio (through the bundled VLC): duration, overall bitrate, resolution; per stream codec, frame rate, channels, sample rate, bitrate, language; tags (title, artist, album, director, season…).
• Archives: the preview tells the format and how it is compressed: method and level (Deflate, gzip level, RAR Fastest…Best, Store), size before and after with the saving, file and folder counts, encryption, solid RAR, recovery record, comment.
• ISO disc images (.iso) open and extract like other archives (ISO 9660 with Joliet long names); the preview shows the label, disc size, bootable, created, publisher and the program that made it.
• Disk images mount from the context menu (Mount): ISO and IMG everywhere, DMG on macOS (hdiutil), VHD/VHDX on Windows (Mount-DiskImage, a drive letter), Linux through udisksctl without administrator rights. The image opens in a new tab and shows in CONNECTED, where Eject unmounts it (on Linux the loop device is freed too).
• Windows: CONNECTED lists the other drives (USB sticks, DVDs, mounted images, network drives).
• SDK: ArchiveProvider::info lets archive extensions describe an archive for the preview (ArchiveInfo).
