When deleting a folder named '~', it starts to delete the whole home folder

[David]

I was deleting an empty folder called ~ through FileZilla.

However, I started to notice that it was taking way too long to delete 8KB. When I looked at the logs, I saw that it was deleting all files in /home/<user>/... instead o /home/<user>/<path>/~.

Sadly, the damage had been done. I'm filling this bug report so this may not happen to anyone else.

I almost did this myself in the console, before I realized I had to use ./~ instead of ~. I'm not sure how FTP works overall, but a possible fix may be to always include ./ or the full path... no idea though.

I am on macOS 10.14.3 on an iMac (Retina 4K, 21.5-inch, 2017).

Here are some logs when it's deleting the files one by one:

Status:      	Directory listing of "/home/<user>" successful
Status:      	Deleting "/home/<user>/<folder>"
Status:      	Deleting 3 files from "/home/mc/<folder_2>"

This is a bug in your server, it wrongly interprets relative paths.

~ has no special meaning in terms of the protocol and hence must not be interpreted specially by the server, yet it does, leading to your loss of data.
