copied!<p>I'm not familiar with NSIS, but you may find this little "DOS" trick helpful. </p> <p>I did notice that it is possible to open a file with NSIS, so this may help --</p> <pre><code>chkntfs c: | find "file system" > yourfile.abc </code></pre> <p>CHKNTFS is a utility for managing the CHKDSK operations, but if you run the command with no command line switches, it simply reports the results. </p> <p>the "C:" is the drive you're interested in --</p> <p>You can run this from a command prompt to see the result, without the <strong>"> yourfile.abc"</strong> part, of course, which is what directs the output into that file.</p> <p>Before anyone down votes this, I just offer it as a thought provoking SUGGESTION, perhaps sparking the real solution and remember SO motto -- be KIND ... lol ...</p> <p>EDIT: this snippet may help -- I have no way to really TEST this -- THIS IS COMPILE TIME USAGE -- and you will most likely want RUN-TIME ... BUT, it may give you an idea ...</p> <p>I "assume" there isn't a define already named NTFS -- if so, change this accordingly. The first call CREATES the include file, the second APPENDS to it (the double > )... The /C option for FIND simply COUNTS the number lines containing the search item. Hence, the 0 or 1 result.</p> <pre><code>!system 'echo "!define NTFS=" > newinclude.nsh' !system 'chkntfs c: | find /c "NTFS" >> newinclude.nsh' !include newinclude.nsh !ifdef NTFS !echo "NTFS is defined and value should reflect accordingly; 0=NO, 1=Yes it is NTFS" !endif </code></pre> <p><strong>EDIT: (again, lol)</strong></p> <p>here's a snippet that will set an ENVIRONMENT variable, which from what I can tell, should be rather easy to read during run-time -- you could construct a variable to execute, replacing the drive letter accordingly.</p> <pre><code>ExecWait 'chkntfs c: | find /c "NTFS" > tempfile.abc' ExecWait 'set /p NTFS= < tempfile.abc' Exec 'del tempfile.abc' </code></pre> <p>Now, an environment variable called NTFS should hold a 0 if not NTFS and 1 if the volume being inspected IS NTFS.</p> <p>Or directly </p> <pre><code>ExecWait 'chkntfs c: | find /c "NTFS"' $0 </code></pre> <p>$0 holds the return code; The results are kind of backwards as this is the ERROR return code. If 0 you HAVE NTFS and > 0 means NO NTFS.</p>
