The correct order of data logging file formats from smallest to largest disk footprint is Binary, TDMS, ASCII, XML.

Binary formats are the most compact representation of data, as they store information in a format that is easily interpreted by computers. Since they do not require additional characters for formatting or encoding, they have the smallest disk footprint.

TDMS (Technical Data Management Streaming) files are a bit larger than pure binary files because they include additional metadata and structural information, which makes them more versatile for data logging while still being relatively efficient in space usage compared to text-based formats.

ASCII files, which store text in a human-readable format, are larger than binary and TDMS files because each character takes up more space (typically 1 byte per character). They lack the structured data capabilities of TDMS and are less efficient for large datasets.

XML (eXtensible Markup Language) files usually take up the most space among the listed formats due to their verbose markup structure. While XML is excellent for data sharing and integration across different systems, its descriptive nature means it is less space-efficient, leading to a larger overall disk footprint compared to the other formats.

This order reflects the relative sizes of the file formats based on how they store data, influencing their
