Regex Rename Issue - Page 2

I've not tested it, but I also think that you wouldn't be able to properly add any existing image files named like that to Sigil on any platform--including Linux. Sigil wouldn't know how to manifest it properly. I'm guessing it would end up manifested as text/plain and show up in Misc rather than Images.

You'd have to rename *.jpg files to your *.09_jpg preference only after they've been successfully added and manifested as image/jpeg in the opf.

I didn't actually add the files, I wanted to rename them temporarily because some of the filenames had 2 full-stops '.' in them and I was having trouble just replacing the first one, so I changed the second '.' to _ and that was when I noticed the issue.

I liked your suggestion earlier about using a slightly different regex though, so I'll use that for the future.

I figured they were probably part of an existing epub. I was just pointing out that when adding external files to a Sigil epub, the file extension is the only (I think) thing that tells Sigil what the media type should be in the manifest.

Yes sure. Sometimes I'm spoiled as a linux user

Linux can and does support file extensions. The only way extensions can really be dropped is to use a program internally to check the initial bytes for some "magic" byte patterns but this is generally not portable. Hiding file extensions is a good way to be tricked into running something you should not. Combining file extensions that match with "magic byte sequences" is the best for portability and security.

Indeed.
