IDEA: try show a "not a previewed format"

[CompSystems]

Hello in Preview [tab] of a file, if the extension is not known it generates "not a previewed format", but XYplorer could try to identify the internal header to show the expected one.

For example many files of n rare programs, are type text or simple images

Show for example, the file XY was detected as an image, trying to open [yes/No]

Feature seen in 2CMD

In the previous capture I would like on xyplorer to clone the idea of
1: showing the free space as an indicator bar
2: a toolbar of at least 2 lines
3: a bar of units found
