Notes about the PH file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The PH file type is primarily associated with 'AOL' by America Online, Inc.. The file IPH.PH is used by the AOL client software versions 6 through 9 to contain the data necessary for AOL to contact its servers for updates, etc.
