There are three Id important for each file - class Id, record Id, column Id. Files are stored in the database in another table than actual class data. Therefore, you need these values for accessing the file.

If you set File deletion type to Delete only file content in the column definition, than a record about a "former" file is kept in the database and property IsFile = false. Otherwise, IsFile = true.
