[jira] [Commented] (IO-295) FileUtils.isSymlinks misses symlink folders on Windows

["Miłosz S (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IO-295?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17291737#comment-17291737 ] 

Miłosz S commented on IO-295:
-----------------------------

Please also note that on Windows there are symlinks AND "junctions":

[https://docs.microsoft.com/en-us/windows/win32/fileio/hard-links-and-junctions]

And {{java.nio.file.Files.isSymbolicLink()}} is not detecting junctions. To detect them, you should check for file attributes of given {{Path}}:

{code:java}
Path p = Paths.get("C:\\some\\path")
BasicFileAttributes attrs = Files.readAttributes(p, BasicFileAttributes.class, LinkOption.NOFOLLOW_LINKS);
boolean isJunction = attrs.isDirectory() && attrs.isOther();
{code}

^Above solution suggested [here on JDK JIRA|https://bugs.openjdk.java.net/browse/JDK-8031083?focusedCommentId=13444574&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-13444574]

> I created a symlink folder via mklink.
> Then, while debugging, I noticed that FileUtils.isSymlink() returns false on this directory, while Java 7's Files.isSymbolicLink() returns true.
