I'm getting a "No Instance(s) Available" error with the wmic command. The command I'm running (from an elevated/administrator cmd.exe window) is:

G:\>wmic datafile where name="file.txt" get creationdate
No Instance(s) Available

The file "file.txt" does exist.

I have found some mention of this problem in other SU questions/answers like the answer here:

Windows Command to get all information/properties of a file

but I have not found any mention of how to fix (or even troubleshoot) this problem.

I'm running Windows 7 Home Premium x64.

When I run "wmic datafile /?" I get usage syntax help: 
G:\>wmic datafile /?

I'm getting a "No Instance(s) Available" error with the following wmic command.

G:\>wmic datafile where name="file.txt" get creationdate

You need to provide the full name (including the drive and path) of the file.

Example:

F:\test>wmic datafile where name="C:\\Windows\\system32\\notepad.exe" get CreationDate
CreationDate
20090714005636.838522+060

Note the use of \\ to escape a single \ in the above example name string.

If you wish to include the following special characters in your string, you must first escape the character by prefixing the character with a backslash (\):

  • backslash (\\)
  • double quotes (\")
  • single quotes (\')

Source WHERE Clause

What are the valid keywords (name, path, ...) for the where clause with datafile?

You can get the property list from the command line using:

wmic datafile get /?

Any of the property names can be used in a where clause.

F:\test>wmic datafile get /?

Property get operations.
USAGE:

GET [<property list>] [<get switches>]
NOTE: <property list> ::= <property name> | <property name>,  <property list>
