Reproduction steps:
1. Open the attached “IN-140064” project
2. Build the large AssetBundle (Tools > Build Large Bundle)
3. Make sure the build finished successfully by checking the Console window and whether the “Bundles” directory was created with files in it
4. Extract the raw SerializedFile (CAB) from the bundle using WebExtract: “./<UnityInstallDir>/Editor/Data/Tools/WebExtract </path to Bundles>/largebundle”
5. Make sure the CAB file was created under “Bundles/largebundle_data/” directory
6. Run “binary2text” against the extracted CAB: “./<UnityInstallDir>/Editor/Data/Tools/binary2text </path to Bundles>/largebundle_data/<CAB File>”
7. Observe the output

Actual result: “Couldn't open file …/largebundle_data/<CAB File> for reading!
Expected result: “binary2text” reads and prints a text representation of the serialized assets
