    Unintentionally duplicated attachments…

    …are easy to prevent with the De-Dupifier

    Accidentally uploading multiple copies of the same file attachment versions into Confluence is very easy to do. This can lead to bloat, requiring manual intervention to clean up.

    Attachment De-dupifier for Confluence automatically filters out these duplicates using their checksums. You will never have to see duplicated attachments again!

    I can't see any documentation on how to use this. The link to the documentation doesn't give any - https://wiki.isostech.com/display/HSC/Attachment%20De-Duplifier%20for%20Confluence%20Documentation Update - Thanks for putting the documentation. It's now clear how it works and it only works on new attachments being added and doesn't look at existing one.

    Hi Gaj, sorry for the broken link. We have updated the page. This app does not require any configuration and just starts working as soon as it's installed. Hope the updated documentation clears things up. Thanks!

    Excellent idea. It should have been built-in in Confluence from v1.0!
