Attributes and elements

Attributes

Attribute	Description	Data type	Required
Name	The name of the file type association. You can use this name to organize and group file types. The name must be all lower case characters with no spaces.	A string with a value between 1 and 100 characters in length.	Yes
DesiredView	The desired amount of screen space to use when the app launches. This view mode preference is a requested value only. The preferred size that you specify is not guaranteed to be honored by Windows, so you should not write code that relies on never getting into a size that is smaller than the preferred minimum size or larger than the preferred maximum size.	An optional string that can have one of the following values: default, useLess, useHalf, useMore, or useMinimum.	No
desktop2:UseUrl	If set to true, specifies that the application can accept a URL, instead of a file name, on the command line. Applications that can open documents directly from the internet, like web browsers and media players, should use this value. When `ShellExecuteEx` starts an application and this value is set to false, the default behavior, `ShellExecuteEx` downloads the document to a local file and invokes the handler on the local copy.	An optional boolean value.	No
desktop2:AllowSilentDefaultTakeOver	If set to true, the app will appear in an "Open With" list, but it won't be the default app for the file type.	An optional boolean value.	No
desktop5:ThumbnailTypeOverlay	An image resource for a thumbnail overlay.	A string with a value between 1 and 256 characters in length that ends with `.jpg`, `.png`, or `.jpeg` that cannot contain these characters: `<`, `>`, `:`, `"`, `\|`, `?`, or `*`. In this string, the `/` and `\` characters cannot be the first or last characters. Also, the string can contain `/` or `\` but not both.	No
