Where Windows Searches for REG.DAT (82810)
The information in this article applies to:
- Microsoft Windows 3.1
- Microsoft Windows 3.11
This article was previously published under Q82810 SUMMARY
Microsoft Windows searches for the REG.DAT file ONLY in the Windows
program directory (by default, this is WINDOWS). If the file is not
found, it will be created whenever an application, the shell (for
example, Program Manager), or the Registration Editor (REGEDIT.EXE)
creates a new OLE registration entry.
Any other occurrences of the REG.DAT file on the hard disk will be
ignored (for example, in the root directory, on the path, in the
SYSTEM directory, and so on).
MORE INFORMATION
Since the shell mirrors the OLE server information registered in
REG.DAT in the WIN.INI file's [embedding] section, the system may be
able to correct itself should the REG.DAT file be accidentally
deleted, which should allow you to continue editing your OLE objects.
Note: Recreating the REG.DAT file from the WIN.INI file entry is done
to maintain compatibility with pre-version 1.0 OLE clients (Microsoft
Excel for Windows version 3.0, Microsoft PowerPoint for Windows
version 2.0, Lotus Notes version 2.0).
If the REG.DAT file is deleted, any data registered for opening and
printing files in the File Manager or Program Manager could be lost.
