  2. Renaming files: either single files or groups, with optional use of templates.

  4. Improved user interface: Advanced Selection Mode improvements; Move from _Rejected; and more

Before installing the new version, please read the following section (Forewarning).


Extended trial period

If you have FastRawViewer v. 1.x installed, then you have a 60-day trial period to see if you need an upgrade to FastRawViewer v2.


This is a major version upgrade:

  • Upgrade policy:
  • If you bought FastRawViewer v. 1.x after January 20, 2021, then a free upgrade is available for you.
  • If you bought FastRawViewer v. 1.x before January 20, 2021, then you can upgrade with 40% off the regular price (can't be combined with other discounts).

Use the upgrade tool to get your new license key or upgrade discount coupon.

Use Menu – Help – Purchase/Activate, then [Upgrade] button to get your new license key or upgrade discount coupon (this button will open our upgrade tool in browser with license data pre-filled).

Inherited Settings

The application Preference settings, hotkey settings, and lists of ‘last used folders’ are shared between the two versions. Downgrading from version 2 to version 1 can be done by deinstalling the new version and installing the old version.

The settings in version 2 whose names have not been changed but whose meanings or effects have (those are graphic mode and several performance settings), have been internally separated, and changing them in version 2 will not affect version 1 (and vice versa).

Hardware and OS Support

  • We have chosen to not support antiquated/outdated OSs (and in the case of Windows, old graphic modes), so the system requirements are as follows:
  • Mac: macOS 10.12 and newer, Intel or Apple M1 processors.
  • There are no other requirements – if your graphics card works with macOS 10.12, then it’s compatible with FastRawViewer 2.0
  • Windows: Windows 7 – Windows 10/64 bit, “a relatively new graphics card” with support for DirectX11:
  • Intel (integrated/CPU): Core 3rd generation (i3/i5/i7-3xxx) processors and newer
  • ATI/AMD: we recommend Radeon HD 5000 and newer.
  • Nvidia: GeForce 400 series and newer
