When I test that I do not read the disk directly

Windows cache reads other disks to 4G But the M-disk of dokany is only 1.3G There is a big gap. Can you tell me why? thank you

I am not sure to understand. Can you add more information like what is the tests and what are the 4G and 1.3G ? Speed / space ...

I'll test the read speed of Windows file cache again and compare it with that of dokany

It seems that dokany does not use Windows cache

When R3 reads files, there will be a cache. But R0 (dokany) ->R3 (Mirror. exe) ->WindowsCache (NTFS)

Then go back the same way. thus. Reading cached file data is much slower.

recommended ：R0 (dokany) read WINDOWS cache
