Change target for symbolic link in windows

Question

How can I change target of already existing symbolic link. Any solution would work: console, powershell,etc.

Important think is to make this change atomically so solution to delete link and then create a new one do not work for me.

Answer 1

This seems to be possible with the ZwFsControlFile function using the FSCTL_SET_REPARSE_POINT control code. At least that's what I gleaned from how Far Manager does it via Process Monitor.

Answer 2

You could use transactional NTFS. See the following functions:

• CreateTransaction
• DeleteFileTransacted
• CreateSymbolicLinkTransacted
• CommitTransaction

The downside is that MS are deprecating support for transactions. In particular transactions are not available in the new file system being introduced in Windows Server 2012.
