Some things were identical, for example .com files were loaded at 0x0100 which meant that before the start of the loaded program there was space for the FCB:
This block would contain the command-line arguments, and have space for working with files (via FindFirst and FindNext), using the same globbing patterns as CP/M supported.
Of course things changed when MS-DOS got support for subdirectories, and later int21 functions expanded filesystem support. Later still .exe files became more dominant as they could be larger than 64k (minus PSP).
