File cleanup
You can safely remove old Connect files from your system.
Log files
Log files are found in the following location. Log files can be removed at any time.
~/Library/Logs/Aspera_Connect
Database file
If you previously installed Connect for all users (that is, system-wide), then when uninstalling, you are able only to remove the Connect database for the current user. To remove the database file for all users, you must locate and remove the database file for each user account:
/Users/username/.aspera/connect/connectdb.data
Alternatively, you can delete the entire .aspera directory after uninstalling Connect, if wanted.
