The FileSystemInfo facet contains properties that are reported by the device's local file system for the local version of an item. This facet can be used to specify the last modified date or created date of the item as it was on the local device.
It is available on the fileSystemInfo property of Item resources.
{
"createdDateTime" : "string (timestamp)",
"lastModifiedDateTime" : "string (timestamp)"
}| Property name | Type | Description |
|---|---|---|
| createdDateTime | timestamp | The UTC date and time the file was created on a client. |
| lastModifiedDateTime | timestamp | The UTC date and time the file was last modified on a client. |
Values for createdDateTime and lastModifiedDateTime vary from the same properties on the Item resource. The values on the Item resource are the created and modified date and time as seen from the service. The values stored in the FileSystemInfo facet are provided by the client.
For example, if a file was created on the device on on Monday, but not uploaded
to the service until Tuesday, the client that uploads the file should write the
fileSystemInfo facet to include the created date on Monday. When the item
metadata is retrieved, the created date for the item will reflect Tuesday, but
the fileSystemInfo facet will show the orignal created date on Monday.
These properties are read/write. If you are uploading a file and know the local client values for these fields, you should include them in the request.
