The FileManager triggers two Read requests when double clicking a folder in the ListView/GridView. The behavior can be observed in the Basic Usage Demo.
When navigationg to a folder in the TreeView using a single click, the component triggers a single Read request.
Could you consider optimizing the request handling when navigating to nested folders, particularly in ListView/GridView, to reduce redundant Read calls and improve performance?
Description
File Manager refresh changes the selected item.
Refresh should not change the selected item if it is available after refresh.
If the selected item is not available after refresh, Preview pane should show No File Selected.

Error
Select Documents folder in Tree View then Excel Document in List View. Excel Document is shown in the Preview pane.
Refresh the File Manager using jQuery in Console.
$("#filemanager").getKendoFileManager().refresh()Excel Document is not selected and Preview pane shows Documents.
Refresh changed the selected item.
Expected behavior
Selected file does not change after refresh.
Example Windows File Explorer. Select a file in the folder and press F5 to refresh the folder.
Description
FileManager calls Create and Destroy instead of Update on move.
That is not what happens in the file system. Move is Update operation where the location of the item is updated. No files are copied or deleted.
Copying files and directories unnecessarily wastes the resources on the server and the cloud where computing and storage operations are charged.
If Destroy fails which might happen because Create and Destroy are executed separately then files are copied and not moved.
Expected behavior
Move calls Update.
Currently file manager supports multiple selection by using ctrl and shift keys. However it will be a nice feature if the selection of multiple files available through checkboxs, for e.g. when hovering the item, a checkbox appears in top left corner, and user can select it or unselect it.
Bug report
File Manager's toolbar overflow button does not show when the items are marked with the overflow setting.
Reproduction of the problem
Current behavior
The overflow button is not displayed when one of the items is configured with the overflow setting.
Expected/desired behavior
The overflow button should be displayed when one of the items is configured with the overflow setting similar to the conventional toolbar widget's items.
Environment
- Kendo UI version: 2022.6.621
- Browser: [all]

Implement a mechanism that allows the content of a folder to be refreshed every time it is opened. Currently, on opening a folder a request to the "read" end point is sent and the content of the folder is loaded. But on subsequent opening of the same folder the FileManager does not send further requests. If there have been changes to the folder's structure, they won't be reflected in the FileManager, because it doesn't refresh the data. An auto-refresh functionality could resolve that.
A configuration option could allow enabling/disabling this functionality, e.g.,
.AutoRefresh(true)
The FileManager component makes the assumption that all files and directories can be uniquely adressed by name and path.
Unfortunately, this isn't true in many cases: identifying a specific file could require additional information (like database record ID or namespace) that cannot be provided globally for the page and therefore needs to be stored individually with each file entry inside the client's datamodel.
(In my case, different entities in the database have their own "virtual storage" where files are references as items stored in a cloud block storage service. This means that I can several files with the same name and path (but diffreent content) referenced in the database or even several files with the same name and folder linked to the same entity).
As a workaround, if there is no need to represent folder structure at all, the "path" field can be used to hold the database ID of the file and that field can then be used by the Javascript that generate the download link (and other file action URLs).
After trying to use a richer object in the JSON returned to the FileManager Read action, I have come to the conclusiong (confirmed by support), that doing so will break the compnent (rename will not trigger any action on the server, update will cause a JS error inside the kendo libraries).
My suggestion would be to add some additional field to the data model to hold domain-specific information. That field should be handeled in a transparent manner by the Kendo component and it should be made available to any Javascript method. Ideally, I would have loved to be able to add a full set of properties to the client-side object but a single additional string property would actually be enough for everything I need to do.
I would like to see a thumbnail of the image in the FileManager for images. Currently it shows an icon for images. In place of the image icon I would like to see a small thumbnail of the image.
