Junction Points
« on: June 18, 2014, 08:04:26 am »
Is there a good way to find Junction point information with WinBatch?

I have a script to identify junction point locations however it pops up cmd windows to do it so I am looking for another way to identify junction point locations.

Windows 7 as a user:
DocumentsandSettings      = C:\Users
AllUsersProfile         = C:\ProgramData
AllUsersDesktop         = C:\Users\Public\Desktop
AllUsersStartMenu      = C:\ProgramData\Microsoft\Windows\Start Menu

You could do something like the following
Code: Winbatch

;;; Can be made more efficient if speed is an issue.
#DefineFunction IsReparsePoint(strDir)
   FILE_ATTRIBUTE_REPARSE_POINT  = 1024
   return DllCall("kernel32.dll", long:"GetFileAttributesW", lpwstr:strDir) & FILE_ATTRIBUTE_REPARSE_POINT
#EndFunction
 

You could use the FAF extender to traverse the directory structure and call the above UDF on each directory.

Tony, I think the FAFFind function returns duplicate directories when dealing with reparse points. Not sure how the FileSearch Extender deals with reparse points.

It is not an issue unless a reparse point is part of a circular reference. Circular references are  mistakes and one of the reason why some Windows 7 directories are by default marked as deny access even to admins.  Circular references are an issue for any software that attempts to both traverse a directory structure and not ignore reparse points.  The FAF extender can be set to ignore reparse points but that is not what you want to do when you are intentionally trying to find them.

Here is a quick and dirty modification of one of the examples in the FAF extender's help file the illustrates one way to obtain the directory reparse points under the 'users' directory on a Windows 8 machine. 

Code: Winbatch
#DefineFunction IsReparsePoint(strDir)
   return DllCall("Kernel32.dll", long:"GetFileAttributesW", lpwstr:strDir) & 1024
#EndFunction

#DefineFunction DirFind(filehandle, strDir )
   handle = fafOpen(strDir, '*', 11)
   While 1
      sFound = fafFind( handle )
      If sFound == '' Then Break
      if IsReparsePoint(sFound) then FileWrite( filehandle, sFound )
      else DirFind(filehandle, sFound)
   EndWhile
   fafClose( handle )
#EndFunction


AddExtender('WWFAF44I.DLL', 0, 'WWFAF64I.DLL')
outputfile = DirScript():'Reparselist.txt'
filehandle = FileOpen( outputfile, 'Write')

DirFind(filehandle,'c:\users')

FileClose( filehandle )

Run( outputfile, '' )
 

A list of shell links could be obtained using the extender to search for '.lnk' files.
