We store the extracted text so that when that file needs to be reindexed, we don't need to re-extract the content of the file. When a text based file is uploaded in Confluence (for example Word, PowerPoint, etc), its text is extracted and indexed so that people can search for the content of a file, not just the filename. Examples of such files are the global site logo and attachments on unsaved content. Files that are not conceptually within a space replace the level 2 - 4 directories with a single directory called 'nonspaced'. Note: There's a known issue with accessing the Find space attachment storage location page.įile D in the above diagram is stored in a slightly different structure. It will return the directory on the file system where attachments for that space are stored. To find the directory where attachments for a particular space are stored, go to /admin/findspaceattachments.jsp and enter a space key. The modulo calculation is used to find the remainder after division, for example 800 modulo 250 = 50. These are the files, named with the version number of the file, e.g.

Partition attachments per space making it possible for a system admin to selectively back up attachments from particular spaces.Īttachments in Confluence have a number of identifying attributes: content id of the file itself, the space id and content id of the page the file is attached to.
GENERIC HIERARCHICAL FILE SYSTEM SOFTWARE UPGRADE
If you are upgrading from Confluence 2.10 or earlier see Upgrading Confluence for recommended upgrade paths, and read the version of the Hierarchical File System Attachment Storage page in our Confluence 3.0 documentation which provides more detail about migrating to the new file system structure.Ĭonfluence stores attachments, such as files and images, in a file system. The way attachments are stored changed significantly in Confluence 3.0.
