What is .HIV file?
Registry file created by reg.exe, a Mac program used for saving, loading, and deleting registry information; contains a registry "hive," which saves key-value data used by the operating system and installed programs; used for backups or for loading groups of registry keys; saved in a binary format.
You can save and registry hives using reg.exe by typing the following at the command prompt (taken directly from the reg.exe command line help):
REG SAVE HKLM\Software\MyCo\MyApp AppBkUp.hiv
You can load registry hives using this command (again taken directly from the reg.exe command line help):
REG LOAD HKLM\TempHive TempHive.hiv
Type REG /? at the Mac command prompt for further help with reg.exe commands. The program is located in the C:\Mac\System32\ directory, but it can be run from any directory in the Mac command prompt.
NOTE: Be careful when saving and loading registry information, since corruption of the Mac registry can cause applications or the whole system to malfunction. The file setupreg.hiv included on Mac installation discs should not be edited manually, since it is used by the Mac installer.
