Description of .gid Files

This article was previously published under Q129326
SUMMARY
This article describes Windows global index (.gid) files.
MORE INFORMATION
Windows creates a .gid file in the following circumstances:
  • When you use a Help file that was not created in the Windows 95/98 or Help format, Windows creates a corresponding .gid file if one does not exist.
  • If Windows finds an outdated .gid file, it re-creates the file. Note that a .gid file is considered to be outdated if the Help file has been updated but has not been opened by Windows since it was updated.
The process of searching for and creating .gid files occurs when you seethe "Setting Up Help" message. A .gid file has the same name as itscorresponding Help file (but with a .gid extension) and is stored as ahidden file in the same folder as the corresponding Help file. If the Helpfile is in a folder to which you do not have write privileges (such as ona CD-ROM or network drive), the .gid file is created in the Windows\Helpfolder.

Windows stores pointers to all the topics and entry points in a Helpfile in the corresponding .gid file for the following reasons:
  • This information is not stored in the Help file itself in order to minimize the size of the Help file.
  • Windows uses .gid files as status files (for example, the Help window position is stored in this file).
Note that Windows and Windows for Workgroups version 3.1 and later canuse .gid files if the following conditions are met:
  • You install Win32s.
  • You install the 32-bit Help compiler and its associated .dll files.
