|
||||
These options affect how duplicate deletion takes place. Most of the time, you don't need to enable
|
||||
any of them.
|
||||
|
||||
* **Hardlink deleted files:** The deleted files are replaced by a `hard link`_ to the reference
|
||||
file. (Only for OS X and Linux)
|
||||
* **Link deleted files:** The deleted files are replaced by a link to the reference file. You have
|
||||
a choice of replacing it either with a `symlink`_ or a `hardlink`_. It's better to read the whole
|
||||
wikipedia pages about them to make a informed choice, but in short, a symlink is a shortcut to
|
||||
the file's path. If the original file is deleted or moved, the link is broken. A hardlink is a
|
||||
link to the file *itself*. That link is as good as a "real" file. Only when *all* hardlinks to a
|
||||
file are deleted is the file itself deleted. (Only for OS X and Linux)
|
||||
* **Directly delete files:** Instead of sending files to trash, directly delete them. This is used
|
||||
for troubleshooting and you normally don't need to enable this unless dupeGuru has problems
|
||||
deleting files normally, something that can happens when you try to delete files on network
|
||||
storage (NAS).
