I am creating an installer with a NSIS program for which to run on NTFS volumes. How can I find out that installing the path is on the volume of NTFS and work accordingly (show help / warning message)?
Using external equipment is not always a good idea (every command line tool on the home versions of windows Does not exist) It is always better to call the API directly in the system plug-in.
! LogicLib.nsh StrCpy $ 0 "c: \" System :: Call 'Kernel 32 :: GetVolumeInformation (t "$ 0", t, i $ {NSIS_MAX_STRLEN}, * i, * i, * i, t.r1 !, I $ {NSIS_MAX_STRLEN}) i.r0 '$ {if} $ 0 & lt; & Gt; 0 MessageBox mb_ok "fs = $ 1" $ {endIf} In this situation, you should not check the file system type, but you need the actual feature (compression, encryption , Junction, sparse file etc)
