I use FTP deployment tool shipped with PhpStorm. When I transfer files, IDE shows process info, see image:
How to view this logs for particular date, for example, for 2 days ago? Does IDE stores file transfer logs via file or via some database?
IDE does not store logs for a File Transfer toolwindow anywhere: they stay in that toolwindow for the duration of a session (or until toolwindow is fully closed).
Sadly, I do not know about possibility of telling IDE to store such log in some file.
