File type specification:
File extension glh seems to have been in the past used for one of the file types in Wise Installer, a creator of Windows application installation packages, which was originally developed by Wise Solutions until the company was acquired by Altiris, Inc. and later Symantec.
It appears that .glh were used for some temporary data storage purposes.
This glh file type entry was marked as obsolete and no longer supported file format.
This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
