Passing multiple tab files into QuickImport via ArcPy only outputs file geodatabase with one feature class?

Question

I'm trying to convert tab files to shape files. Issue is my code below converts only the last tab file in the os.walk list and not all the others. No python errors are reported and output prints the list of tab file paths below. Can anybody see something wrong as to why Quickimport converts one tab file and not the others?

C:/temp\Boundary.TAB 
C:/temp\circle.TAB 
C:/temp\square.TAB 
etc,

import arcpy 
import os

path = "C:/temp1"
for root, dirs, files in os.walk(path,topdown=False):
    for file in files:
        if file.endswith(".TAB"):
            table = os.path.join(root, file)
            print(table)
            output = "C:/temp1/results.gdb"
            arcpy.QuickImport_interop(table, output)

Answer 1

I think the reason that you are only ever seeing one output feature class in that output file geodatabase is that, each time you run the Quick Import tool (which I do not recall ever having tried), the file geodatabase that you are writing to gets overwritten.

In the Using the Quick Import tool help it says:

A geodatabase is created containing the converted input data.

Each time that Quick Import runs in your loop it does not write the new feature class to the same file geodatabase as I think you are assuming. Instead it deletes that file geodatabase, creates a new one, and then writes the feature class into that new file geodatabase.

I prefer to use FeatureClassToFeatureClass rather than QuickImport for converting MapInfo TAB files to file geodatabase feature classes using the ArcGIS Data Interoperability extension. That tool copies feature classes into an existing file geodatabase; it does not create a new file geodatabase.
