wrong. basically 'locate empty clusters and TRIM' requires no interaction
with filesystem at all; at least in single tasking OS.

if you consider FAT complex, stop writing in this forum.

I assume this is all new and undiscovered area for you.

DEFRAGGing and CHKDSK are orders of magnitudes more complicated to implement as this process has many more variables.
