Description

IsPatched is a Boolean function used to indicate if patches in the Differences property have already been applied using the Patch method. IsPatched performs a rudimentary test for the file specified in Filename; the file must exist and its' size is examine to determine if it matches the size stored in the Differences property. It does not perform any in-depth comparison of the contents with the file specified in StartFile.
IsPatched returns False when Filename cannot be located, Differences contains an invalid format, or when the size of the file in Filename differs from the value for the patched file in Differences.
