I've found a description of hard links and junctions in Windows, however I'd like to know ,from the Windows UI or command prompt, how I can view the hard links of a particular file or folder?
fsutil utility included in Windows XP and higher. Example:
fsutil.exe hardlink list C:\Windows\System32\notepad.exe
Sample results (from Windows 7):
\Windows\System32\notepad.exe \Windows\notepad.exe \Windows\winsxs\amd64_microsoft-windows-notepadwin_31bf3856ad364e35_6.1.7600.16385_none_9ebebe8614be1470\notepad.exe \Windows\winsxs\amd64_microsoft-windows-notepad_31bf3856ad364e35_6.1.7600.16385_none_cb0f7f2289b0c21a\notepad.exe
fsutil requires elevated system privileges. If you just need to read, and not create, links this is very inconvenient.
Microsoft releases also the free findlinks, which is much more syntax friendly, gives extra-details and does not require special privileges.
Judge yourself the same file, as from John K post, analysed with
findlinks c:\windows\notepad.exe FindLinks v1.0 - Locate file hard links Copyright (C) 2011 Mark Russinovich Sysinternals - www.sysinternals.com c:\windows\notepad.exe Index: 0x000037A6 Links: 3 Linking files: c:\Windows\System32\notepad.exe c:\Windows\winsxs\amd64_microsoft-windows-notepadwin_31bf3856ad364e35_6.1.7600.16385_none_9ebebe8614 be1470\notepad.exe c:\Windows\winsxs\amd64_microsoft-windows-notepad_31bf3856ad364e35_6.1.7600.16385_none_cb0f7f2289b0c 21a\notepad.exe
While the convenience of
findlinks might persist,
starting with Windows 10 Insiders build 14972, symlinks can be created without needing to elevate the console as administrator.
One can also observe that now
fsutil.exe does not require elevated privileges any more.
Microsoft's goal is to align the symlinks functionality to Linux standards, where they are very common.
Thanks to pinjaliina for pointing out this.
Not directly what you need but may still be useful for such goal when used cleverly:
FINDDUPE, a standalone command line utility hosted at http://www.sentex.net/~mwandel/finddupe/ address, has side functionality, which allows listing all hardlinks within a directory recursively with the following call:
finddupe -listlink <directory_of_interest>
Here is an example of what one gets as an output:
Hardlink group, 2 of 2 hardlinked instances found in search tree: ".\1" ".\_1" Number of hardlink groups found: 1
NOTE: There is a number of projects with the similar name on SourceForge, but nothing actually hosts the utility above as for now.
The FindLinks tool from Sysinternals should be exactly what you need.
Try the program NTFSLinksView - works fine for me on Windows 10, should work on Vista and later.
