Any idea why ExcludedExtensionsForPreview is not working? I've also tried it with "*" and ".*" which also does not work. We want to disable all previewing since we are not able to pre-cache the files and some of our documents are taking over a minute to load in preview.
We are currently using FileUltimate version 5.16.0 and GleamTech.Core version 2.0.1
FileManager fileManager = new FileManager()
Width = Unit.Percentage(80),
Height = 500,
Resizable = true,
DownloadOnDoubleClick = false,
ViewLayout = ViewLayout.MediumIcons,
ExcludedExtensionsForPreview = ".pdf, .xls, .doc, .docx"
