Directory Opus plugins

Directory Opus is a file manager for Windows. It includes thumbnail support and allows viewing various file formats within the program. The number of supported formats can be extended through a plugin system.

Universal Graphics Viewer (UGV) plugin

This plugin utilises the excellent GFL graphics library to provide support for 161 formats (including HDR. NOTE: some formats are already supported by Opus). It supports thumbnails, the Viewer/Viewer Pane, and conversion from any of the supported formats.

This is an early beta release, but it shouldn't have any major issues. We hope to add support for EXR in the near future. Most of the testing has been performed on Windows 7 64-bit with Opus 10 64-bit, so there may be the odd issue with the 32-bit version.

If you have any comments, suggestions, or bug reports, please contact via e-mail (see Contact Us link at top right) or forum (forum will be up in the near future). This plugin is free for everyone, but please consider making a donation if you find it useful.


You can download from here


To install, just extract the contents of the ZIP archive to the Directory Opus program folder (usually C:\Program Files\GPSoftware\Directory Opus\).
