Enabling thumbnails and previews

For generating file thumbnails and previews, FileRun uses various third-party software.

Any of the following are an option: Vips, ImageMagick / GraphicsMagick

Vips is recommended for very fast generation of image files.

ImageMagick is recommended for supporting other types of files, such as PDF and PSD.

Please see https://www.libvips.org/install.html

Please see https://imagemagick.org/script/download.php

GraphicsMagick is a fork of ImageMagick and works almost identical, but in some cases it can be faster and more efficient than ImageMagick.

For ImageMagick/GraphicsMagick to be able to generate thumbnails for PDF documents you might also need to install Ghostscript.

Make sure the Ghostscript app also has permissions to write to the server's temporary folder.

The current Ghostscript distriubtion (older than V9.56) has various security problems, so it is recommended that you always install the latest version:

wget https://github.com/ArtifexSoftware/ghostpdl-downloads/releases/download/gs9561/ghostscript-9.56.1.tar.gz
tar xvf ghostscript-9.56.1.tar.gz
cd ghostscript-9.56.1
./configure
make install

ImageMagick might require “dcraw” and “ufraw” utilities in order to support RAW image files. If you can't get ImageMagick to work with your raw files, give GraphicsMagick a try as it has better support for it.

After installation, you will need to manually enable the use of these third-party utility programs in FileRun's control panel, under Files » Thumbnails and preview.

Example of valid paths:

Windows servers: C:/ImageMagick/magick.exe
Windows servers: "C:/Program Files/ImageMagick/magick.exe" (Using double-quotes because of the space character in the path)
Linux servers: /usr/bin/convert
