As I try to use DT and DTTG more, not only to store and search content, I noticed that Markdown files with the ending “*.md” are shown as “E-Book” kind in DT.
I have no idea why this could be.
When I double-click on them, the App “Calibre” opens because of this.
Is there any way to fix this in DT?
When I try the same with “*.txt” files, DT opens “TextEdit” instead, which would also be perfectly fine for Markdown files.
No, because it is not a DEVONthink issue and it’s one that has been discussed here often. You need to select an .md file in the Finder, press Command-I and choose your desired application in Open With. Then press the Change All button.
