Indication of File Compression Status

MDA supports reading and writing of MDF V4.3 files using advanced compression algorithms, specifically ZSTD and LZ4. In contrast, older formats utilize standard Deflate (MDF V4.1) or have no compression at all (MDF V4.0 or earlier). MDF V4.3 defaults to ZSTD, which offers significantly higher compression ratios while maintaining fast processing speeds.

In the File Explorer of MDA V8, the icon indicates whether the measure file format supports file compression or not.

The status of the file compression is also listed in the measure file tooltip and Information window.
