What is an haw file?
.haw is the file extension used for HyperACCESS session files. These files store your connection and terminal emulator settings as well as any automation or file transfer settings you have set up.
The haw file is created automatically when you set up a connection in HyperACCESS. By default it is saved into the HyperACCESS My Files folder, but more often you will open your session files from the HyperACCESS Phonebook (or other notebook) tab.
