Windows 11 25H2 File Explorer Preview does not work with Mountain Duck 5.3.2

On Windows 11 25H2, File Explorer Preview does not work with Mountain Duck 5.3.2 in integrated sync mode.

For any commonly-previewed files (.jpg, .pdf, etc.) which are in the Mountain Duck vaults, Windows shows a blank Preview area.

If the same files are moved to another non-Duck directory, the File Explorer previews are available immediately.

We are working on support for thumbnails for files in Integrated connect mode for selected protocols that support retrieving a thumbnail from the storage location for Google Drive, Dropbox and OneDrive. In general thumbnails are not displayed for placeholder files on disk as that would otherwise require to download the full content length of the file.

@dkocher Does the generation of thumbnails equate to the ability to utilize the File Explorer Preview function?

When a user is viewing files in File Explorer, the interface includes a button for "Preview" which opens a panel that displays a preview of any previewable clicked file. It doesn't seem that this Preview displays thumbnail files, however, but a full-res preview of the file.

When viewing files in a Mountain Duck folder, the Preview function always appears blank.
