I've never done this, but as long as you don't touch the file from Evo (i.e. visit the folder) and of course assuming it's not your Inbox, then I don't see why not. > 2) In .evolution/cache/ I currently have 100MB, mainly contained in the > html subdirectory.

However you can create a temp directory somewhere else and place a symbolic link to it where Evo expects to find it.

Again, use --force-shutdown to stop Evo before doing this. However if you don't have enough space for an expunge, I don't see how you're going to be able to edit large mbox files, since an expunge is essentially just that. > 5) Where can I find a description of the set of files for each folder, > e.g. Inbox, Inbox.cmeta, Inbox.ev-summary, Inbox.ev-summary-meta, > Inbox.ibex.index, Inbox.ibex.index.data > Why so many sub-files in addition to the main one Inbox? Several reasons. Some are indices into the mbox file (which is a potentially very large linear file with messages separated by an inline syntactic convention, making it inefficient to jump randomly between messages). Some are caches of message state, which eventually has to be pushed to a mail server (e.g. for IMAP). Others are there because Evo supports folder nesting and the mbox format doesn't, so it needs extra information. Offhand I can't point you to a unified description of all this, but http://www.go-evolution.org/Main_Page might be a place to start. poc _______________________________________________ Evolution-list mailing list Evolution-list@gnome.org http://mail.gnome.org/mailman/listinfo/evolution-list
