The Preview feature, when enabled allows displaying the user file list in Thumbnail View mode, for most popular image, document and video file formats.For documents, a thumbnail image of the first (usually title) page is rendered, for videos, 10 slides evenly sampled along the duration time.


Prerequisits:#


Thumbnails generation relies on widely used free 3rd party conversion utilities, either part of the host operating system ( qlmanage in case of Mac OS ), can be downloaded from either the OS apps repository ( Linux yum and apt), or as a standalone package from the maintainer's site ( Windows, all OS).
The Preview settings page has a dropdown selector list displayed dynamically based on the host OS platform, we'll display the available presets for image and video preview. In case of Windows, Linux the conversion utilities need to be deployed manually.

Image and document files:#

On Windows and Linux platforms need to deploy GraphicsMagick for image formats and also Ghostscript for documents. On Debian based platforms the packages are readily available from the apt repository
some code block



Heading 2 title#

Holding down the Alt key while click the Add Folder button allows adding remote items (FTP://, SMB3://, etc.)

So the top half of the window in general you don't touch or change anything. Just use the preset menu. The bottom half of the window, you specify directories that CrushFTP should monitor for new files. When it sees a new file, it generates a thumbnail for that file.

You can also have thumbnails generated for movie files. OS X has a built in method for doing this, other OS's can use other utilities such as FFmpeg. Still frames will be grabbed out of movies and made available as the mouse hovers over the icon.
