Confluence Server Error

If clicking Download All Attachments ends up in Confluence server error, the reason is as follows.


Clicking this button makes Confluence save all attachments to disk to create a zip file. But as you can see, it has some png files with time separated by : , these are images copy pasted to the page. The problem is, unlike *nix, Windows doesn’t allow to have special characters in the filenames. So, trying to save such files to disk just results in crash. Obviously, Atlassian developers failed to port their software from *nix to Windows the proper way.
So, in this particular case you’ll have to download attachments manually. In the future, either avoid copy-pasting images or migrate your Confluence installation from Windows to *nix.
