How to set default metadata for a file.

Hi,

Is it possible to modify value of default metadata for a file (let say value of kMDItemFSSize OR kMDItemPhysicalSize) ?

Actually I want to display a virtual file icon in finder with some customized values of default metadata.

Below is the list of default metadata for a file:

kMDItemContentCreationDate = 2015-06-18 08:06:50 +0000

kMDItemContentModificationDate = 2015-06-18 08:08:11 +0000

kMDItemContentType = "public.plain-text"

kMDItemContentTypeTree = (

"public.plain-text",

"public.text",

"public.data",

"public.item",

"public.content"

)

kMDItemDateAdded = 2015-06-18 08:08:11 +0000

kMDItemDisplayName = "test.txt"

kMDItemFSContentChangeDate = 2015-06-18 08:08:11 +0000

kMDItemFSCreationDate = 2015-06-18 08:06:50 +0000

kMDItemFSCreatorCode = ""

kMDItemFSFinderFlags = 0

kMDItemFSHasCustomIcon = (null)

kMDItemFSInvisible = 0

kMDItemFSIsExtensionHidden = 0

kMDItemFSIsStationery = (null)

kMDItemFSLabel = 0

kMDItemFSName = "test.txt"

kMDItemFSNodeCount = (null)

kMDItemFSOwnerGroupID = 20

kMDItemFSOwnerUserID = 501

kMDItemFSSize = 3621

kMDItemFSTypeCode = ""

kMDItemKind = "Plain Text Document"

kMDItemLastUsedDate = 2015-06-18 08:08:11 +0000

kMDItemLogicalSize = 3621

kMDItemPhysicalSize = 4096

kMDItemUseCount = 2

kMDItemUsedDates = (

"2015-06-17 16:00:00 +0000"

)

Thanks in advance.
