You can choose whether to create the context menus Delete with UVK and File information when installing the software or by checking the corresponding checkbox in the UVK Options section. Use this context menu to delete files and folders you can't delete using windows explorer, or to get extended information on a file.

If you've created it, then the Delete with UVK  context menu  will be available when right clicking any file or folder.
The File information context menu will be available for all files (see picture below).

Context menu Delete with UVK

After clicking this context menu, you'll be prompted to confirm to delete selected items, as shown in the picture below:

If you click No, the selected file or folder won't be deleted.

If you click Yes, it will be moved to the recycle bin as written in the message box. For running executable files, corresponding processes will be terminated before deletion.

If the selected file or folder is locked by another application, it will be scheduled for removal on reboot. A message box will be displayed like the one in the picture below:

Click OK to reboot immediately or Cancel to do it manually later.

After restarting your computer, you'll see a report on your desktop with details of the reboot deletion(s).

Be careful when deleting shortcuts with this feature, because it's the shortcut destination file that will be deleted, instead of the shortcut itself.

This isn't a UVK bug. It's the windows shell that sends the destination path instead of the shortcut to UVK.

Also, if you selected several files or/and folders and used the context menu Delete with UVK on the seletion, then each selected item will open an UVK instance and will be deleted separately.

Again, this is a windows shell feature and has nothing to do with the UVK's configuration.

To delete several files and/or folders simultaneously, including shortcuts, select them and then drag the selection to the UVK's desktop shortcut. Then all the items will be deleted in sequence with the same UVK instance (see picture below).

Context menu File information

When you click this context menu, a dialog box like the one in the picture below will be displayed.

As you can see in the screenshot above, the dialog shows several information fields and some buttons to perform extra actions.

By default, the publisher displayed is not verified. Click Verify to verify it. Click the Check button to check if the file is infected using the VT api.

Click the VirusTotal MD5 report button to generate a html report on your desktop.

Click the File properties button to open the file's properties dialog.

Click the Close button or just press esc to close the dialog box.
