Are you saying that you haven't seen a pop-up window confirming the deletion so far

[yu2chuan]

a pop-up window confirms the deletion.
but, my suggestion

1. if there is the other files in this folder, this folder including not markdown files will be deleted.
2. if all files are md file in this folder, this folder including 7 markdown file will be deleted.

Sorry, I still haven't figured out what your expected outcome is? I haven't confirmed the pop-up window or deleted the contents of the folder cleanly?

Under normal circumstances, this is the way it behaves. Click on 'Delete Folder' -> a pop-up prompt prompts for confirmation
-> after confirmation, delete all files in the folder

If users manage the files with Markflowy UI, users can only see md file but other files like docx in the same folder. Users could accidently delete this docx file when deleting the folder.
If markflowy detects not-md file in the same folder, the message should confirm users that there are not md files in this folder will be deleted together.

I understand, I'll think about it again. I don't know if displaying all the files in the folder is a good choice?

If the program detects some xls, pdf files in the folder user will delete, the message can be "xls, pdf, etc in the same folder will also be deleted. Confirm deletion?

This is also good, it should be a good optimization for interaction
