There is a relevant topic from 20 years:
Regression in 3.4.2 (build 197) with '~ ' at begging of directory name
I'm using WinSCP 5.21.8 to connect to a Synology DiskStation with SFTP. Trying to open the
~cosmic horror directory results in
"Error changing directory":
Command 'cd ~cosmic horror'
failed with return code 1 and the following error message.
-sh: line 72: cd: ~cosmic: No such file or directory
Seems like the command should've the directory name enclosed in quotes, but hasn't.
Opening a directory containing a tilde or a space, but not both, works fine.
