I'm using SVN for several projects that contain large binary files which are needed by the project but will never be modified (or they'll be modified on very rare occasions and I don't need to track their changes anyway).
As they're part of the project, I'd like to keep them "linked" to the project so that they would be retrieved when performing a checkout (or update if they're missing), along with all versioned files. But I don't need (and don't want) to have them versioned by SVN to save some space in the repo and avoid unwanted data duplication if someone modify/commit them by mistake.
Right now I'm using svn:externals on another repository (read-only), but something like svn:externals allowing links to non-SVN sources like an FTP folder would be even better.
Do you know any SVN trick or convenient tool that could help? Thanks!
