There is a single FastRawViewer Manual (in pdf format) for both Windows and Mac OS X versions (the manual comes with the installation, too).

How to choose the proper version of FRV

for Mac OS X

FastRawViewer for Mac OS X requires any Intel-based Mac (excluding Mac Mini 2005) with Mac OS X 10.6+ installed. We recommend a video card with OpenGL 2.1 support (that's every native Mac video card that works with OS X 10.6). An OpenGL emulator will be used if such a video card is not present in the system; some of the advanced features of FastRawViewer will take significant time to render without hardware support for OpenGL.

for Windows

FastRawViewer for Windows requires a computer with SSE3-compatible CPU (that is, manufactured after 2004) and not-so-ancient video card. It works on a variety of 32/64 bit Windows platforms: XP, Vista, 7, 8, 8.1 (we suggest Windows 7 or 8.1/64-bit).

FastRawViewer for Windows is available in 2 versions:

  • Graphics based on Microsoft DirectX - this version will work with any video card that supports DirectX 9.0 and higher (DirectX 9.0c support or later is recommended)
  • Graphics based on OpenGL - requires a video card with at least OpenGL 2.1 support. Works fine on modern discrete graphics card with up-to-date drivers, slightly faster than DirectX version. This version may experience compatibility problems with older hardware and/or outdated drivers. OpenGL version is recommended for these graphics cards: Nvidia Geforce GTX4xx and newer; AMD/ATI: Radeon HD5xxx and newer.

We do not *officially* support Windows 10 in FastRawViewer v1.1, although for ~99% of Windows10+FRV users it works OK.

We’ve had several complaints (literally: one or two) about compatibility, all received for Windows 10 in multi-monitor setup. All of these problems were solved by switching from the DirectX version to the 64 bit OpenGL-graphics version.

Also, you can try before you buy: FastRawViewer trial mode is fully functional for 30 days. It is known not to break Windows 10 systems, so no worries.

Next version, FastRawViewer 1.2, will have ‘official’ support for Windows 10.

If you are having graphic issues

If you are experiencing sluggish behavior, or any graphic issues, updating video drivers may be very helpful. In fact, we suggest to keep your video drivers up-to-date in any case.

Camera support added

  • Nikon D810A
  • Panasonic DMC-GX8
  • Sony A7R-II, RX10-II


Fixed the program behavior for the case when the folder change is initiated through Folders panel:

  • 'Copy to Folder' and 'Clear _Rejected' actions are deactivated (they will be active after a file selected through Thumbnails panel is displayed in the main window)
  • the list of rejected files is cleared and 'Restore from Rejected' action is deactivated
  • if the new folder contains RAW or JPEG images, 'First/Last file in folder' actions become active.

FRV 1.1.2 Changes

Camera support added

  • Canon 5DS/5DS R in sRAW/mRAW modes
  • Canon G3 X
  • Fujifilm X-T10
  • Leica Q
  • Olympus AIR-A01
  • Panasonic DMC-G7
  • Pentax K3 II (first subframe for 4-shot images)
  • Sigma dp3 Quattro, dp0 Quattro (JPEG only)
  • Sony RX100-IV

FRV 1.1.1 Changes and bugfixes


  1. Filmstrip/Thumbnails Panels:
    • New preview size, 75x50 pixels
    • The filename can be displayed in the tooltip
  2. Folders Panel:
    • Display of folder and drive icons can be turned off to save space
    • Removable media change monitoring can be turned off
    • Windows: the display of letters for removable drives with no media inserted can be turned off
  3. Windows: experimental support for operations with non-mounted volumes (\\NAS\share\path)
    • Preferences - Removable Media - Show unmounted network volumes in Folders panel, this setting will switch on the display of the contents of the current un-mounted volume in this panel (if this setting is Off, the network devices that do not have a drive letter assigned will not be displayed).
    • Such a volume will be displayed in the panel only after an image file (RAW or JPEG) from this volume will be opened using standard actions: Drag-n-Drop, Menu - File - Open, Menu - File - Open Folder.
    • Again, this is an experimental support, it was subjected only to a limited testing. If you encounter any problems, including FastRawViewer crashing, please turn it off.
  4. Camera support
    • Canon: 750D, 760D
    • Leica: Monochrom (Typ 246)
    • Nikon: 1 J5


  1. If the user cancelled (after a warning) the operation of "Move to _Rejected", new files wouldn't open through the Thumbnail/Filmstrip panel (File-Next File and other "File" actions - continued to work).
  2. Fixed bug in EXIF parsing code when parsing broken EXIF data.
  3. Windows: fixed FastRawViewer shut-downs caused by the OS's icon and folder provider being buggy or just crashing (the problem was noticed only for the versions of Dell Backup & Recovery released before September 2014).:
    • The icons built into FRV are used by default in the Folders panel (to use the system icons, go to Preferences - Interface - Use built-in drive/folder icons);
    • The icons built into FRV are used in the FRV (as opposed to system's) file select dialogs (to use system dialogs, go to Preferences - Interface - Use built-in icons in Open File/Open Folder dialogs).
    • During the first start of FRV, it searches for Dell Backup & Recovery - and if it is found, Preferences - Interface - Use system Open File/Open Folder dialogs is turned off.
  4. Windows: a problem caused by "too intensive monitoring" of removable media is fixed, the strain on removable media is now decreased
  5. Windows: the monitoring of removable media on disks A: and B: is turned off by default, these disks are completely ignored.
    • It can be turned back on (may be necessary if you have a card reader on A:/B:, for instance) through switching off Preferences - Removable Media - Disable A: and B: floppy access (this setting in Preferences was created because many users have a floppy controller enabled in BIOS, but no floppy drive physically connected to the controller on the motherboard, and as a result any request to A:/B: can take several seconds; generally, this request occurs during the program start, to check for the presence of a floppy disk in the disc drive).
  6. OS X: FastRawViewer crash occurring for slow media / network media devices when opening an explicitly specified file (by dropping it in, or identifying it in the command line) placed very deep in the folder hierarchy (deep nesting level) is fixed.

What's new in FRV 1.1

New, major improvements

  1. Filmstrip/Thumbnails panel previews the current folder's files. The thumbnails are extracted from the previews built into the RAW files; if the RAW file has no preview (such as with Cinema DNG), then the thumbnail isn't displayed. Aside from the thumbnail, the panel optionally shows the file name, rating, XMP label, title, and description. What exactly is displayed and how it is displayed can be controlled through the 'settings' button (gear) on the panel title.
  2. Folder panel with folder tree display, and fast navigation through it.
  3. Removable media support (flash cards, etc.):
    • automatic detection of an inserted card, and a possibility to automatically start browsing in the most recent folder.
    • unmounting a card without exiting FRV.
  4. If one closes the new panels and restarts FRV, then it will behave as previous versions (doesn't decode previews, does not monitor changed media), correspondingly the performance remains as it used to be.
  5. Support of display and editing of XMP/IPTC Title and Description. Displayed on the XMP data panel, can be edited via Alt-D.
  6. The color scheme of the informational panels can be tuned through Preferences - Interface

New, minor improvements

  1. Menu - File - Reveal in Finder (Mac) / Show in Windows Explorer Displays the currently opened file in the file structure
  2. Mac: Proxy Icon in the window title, acts like with all Mac programs (the icon can be dragged to other programs; Command-Click displays the menu with the folder hierarchy).
  3. New Feature: "File Handling - Open Folder dialog starts at" with the options
    • Current folder
    • One level higher
    • Fixed folder


  • Preferences have been reworked, the new descriptions are available in the documentation.
  • The default manner of starting without specifying a file to be opened is Last Visited Folder.
  • Support of Open Multiple Folders has been removed (obsolete)
  • The default buttons for opening/closing informational panels have been changed; instead of letters, now the F2-F7 keys are used. Old settings will continue to work, until the user resets the settings to defaults.

Bug fixes

  • XMP recording during switching between the files has been prohibited
  • If a file has both an XMP block inside, and an external sidecar file, and both blocks have the tag xmp:MetaDataDate, then the more recent set of XMP data is used.
  • Processing speed of large folders on slow storage devices (network, removable media) has been significantly increased
  • Bug fix: when changing the sort order of files in a folder, the new order was applied only starting with the next folder; the current one wouldn't be re-sorted.
  • Bug fix: the "XMP Rating Plus' action was applied only if a file already had a rating.

New Camera Support
