When to use "file import and export" and where can use "Import and load data" option?

Summary:

Could you please clarify when we should use the “File Import and Export” (used for lookup value load) function versus the “Import and Load Data” (used for job load) option in Oracle HCM Cloud?

I understand one is for file transfers and the other is for actual data loading.

File import and export: Tools > File Import and Export

Import and Load Data: Navigator > Data Exchange > Import and Load Data

If i want to add more grades in bulk do I need to use job.dat template via "import and Load Data".
