use case to 'Name and Extension', 'Full Qualified' and 'Name Only' options in foreach file enumerator in ssis

Hello There,

I am trying to find the use case scenario for when to use

1. Name and Extension

2. Fully Qualified

3. Name Only

while importing flat-file type files from source in SSIS.

Would anyone help me understand the use case scenario for each of the 'retrieve file name' type.

Thank you for giving your valuable time!
