Thanks for answer Steve.
But, how can it help me ?
I have found in docs:
param1 - imFileAccessRec8 *
param2 - imFileInfoRec8 *
Describe a clip, or a single stream of a clip if the clip has multiple streams. Called when a specific
file is instantiated. Importer checks file validity, optionally allocates file instance data, and de-
scribes the properties of the file being imported by populating the imFileInfoRec8.
Return from imGetInfo8 to indicate that there are more streams
to describe. Premiere will send imGetInfo8 for the next stream.
So, as I understand, imIterateStreams describes just media streams of single file,
but it has no relation how to specify multiple files during import.
Now I'm using imGetPrefs8 selector to specify file path.
Please explain me where I'm wrong.
