MRW at a glance
MRW
Convert to MRW when preserving Minolta-origin camera raws or working with historical photo collections from that ecosystem.
It is useful for archive retention and legacy raw recovery.
WMF at a glance
WMF
Convert to WMF when preserving compatibility with older Windows document workflows, embedded legacy graphics, or archive recovery tasks where that classic metafile format is still expected.
It is useful as a bridge for historical Office-era vector assets.
For contemporary vector exchange, EMF, SVG, or PDF are usually more practical.
