This is what I know about all the stuff Microsoft Office throws in your System Folder. I could really use any information people can provide on these things. • Microsoft Dialog Library (vSDM3.02): ? • Microsoft File Library (v1.0): ? • Microsoft Mail Library (v1.0): only necessary if you are using Microsoft Mail. • Microsoft Office Manager: if you have it installed, you'll see the MOM menu in your menu bar. Microsoft Office Manager Patch for 7.5.2/7.5.3 has been released by Microsoft, which updates Microsoft Office Manager [MOM] to version 4.2.1. The patch corrects a problem with System 7.5.2/7.5.3. In addition, you could just get the newest version of MOM, 4.2.1c, which also "fixes" these problems. I would still trash the Office Manager, though; IMHO the functionality isn't worth the "crash risk factor.") NOTE: Microsoft has updated the entire "Office" package to v4.2.1b. To update, you need to re-install the entire package off the new 4.2.1b CD-ROM. According to Microsoft, if you are using v4.2.1b, you do not need the Microsoft Office Manager Patch or version 4.2.1c "unless you have crashes." ;-) • Microsoft OLE Automation (v2.06): ? • Microsoft OLE Extension (v2.06) [<.5/0]: used for "Object Linking and Embedding" -- important if you're using MS products and you want to embed an Excel worksheet within a word document or a PowerPoint presentation. It is functionally similar to publish and subscribe, but much more elegant in use (but a memory hog)... Some people say it's actually closer to the idea of OpenDoc. If you insert an Excel spreadsheet into a Word document and then make changes to the spreadsheet at a later date, the Word document will automatically reflect those changes. This extension is also needed when using the new Word and Word Perfect filters for Quark XPress. These filters import Word and WordPerfect for DOS/Windows as well as their Macintosh versions. OLE is also required to run PageMaker versions prior to 6.0.1 (6.0.1 will run without it, but linking and embedding features will not function). • Microsoft OLE Library (v2.0.6): ? • Microsoft Tool Editor (v1.2): allows custom dialog design. • Microsoft Tool Editor Library: ? ODBC: ODBC stands for Open Database Connectivity, a protocol which allows users to access central databases stored on ODBC servers. o ODBC Configuration Manager (v1.0): shared library which provides support for access to ODBC server-client databases. o ODBC Driver Manager (v1.0): shared library which provides support for access to ODBC server-client databases. o ODBC Setup: ? o ODBC SQL Server ADSP Netlib (v1.0.2): shared library which provides support for connecting to an SQL database server using the AppleTalk Data Stream Protocol (ADSP). o ODBC SQL Server Driver (v1.02.07): shared library which provides support for access to an SQL server. o ODBC SQL Server Setup (v1.02.07): shared library which provides support for configuring an SQL server. o ODBC SQL Server TCP/IP Netlib (v1.02.05): shared library which provides support for TCP/IP access to an SQL server. • Office 4.2.x Update for PowerMac [2/0]: fixes certain crashes on PowerMacs using the different Microsoft Office applications. Specifically, this extension contains the following fixes: o A fix to prevent hanging or type 11 errors when printing using QuickDraw GX o A fix to prevent hanging or type 11 errors when launching a PPC-native application after quitting out of Word. This extension is necessary even if you have updated the "Office" package to v4.2.1b. However, according to Microsoft, if you have updated Word to v6.0.1 and aren't using Excel and QuickDraw GX together you do not need this extension, as the fixes it provides were rolled into the application itself. They even go so far as to say that you should delete this extension before installing System 7.5 Update 2.0. The version (v1.0) of Office 4.2.x Update for PowerMac released with Office 4.2.1a conflicts with even the newest version of Apple Menu Options. If you want to use Apple Menu Options, you should update to v1.0.1 (of course, unless you are using Word 6.0.1a, in which case it is unnecessary). Isn't this fun? If you are using QuickDraw GX, Microsoft suggests downloading the "extension to prevent hanging power mac apps" version 1.0.1 from:   • Q+E ODBC FoxPro Driver (v1.2.0): shared library which provides support for access to FoxPro server-client databases using the ODBC protocol. • Shared Code: this is actually a folder which is located in the "Extensions" folder. It contains the OLE code files (OLE Reg Dll, OLE Server Dll, Ole Client Dl) used by the "Shared Code Manager" of the Microsoft OLE system. • Shared Code Manager: lets programs share common code. Provides Microsoft's object linking and embedding (OLE) system. It is similar to the Shared Library Manager for the shared libraries. Installed by Microsoft office along with the shared code modules Ole Client DLL, OLE Reg DLL and OLE Server DLL (in a the above "Shared Code" folder in the Extensions folder). This extension is also supposedly installed by PageMaker 5.0. This file isn't necessary for MS applications to run, but OLE will not function without it. The "Shared Code" folder must be present for the system to run. • Visual Basic for Applications (v1.01) NOTES: I have been told that you can run Microsoft Office fine with only these files installed: • Office 4.2.x Update for Power Mac • Shared Code Manager" installed (along with the "Shared Code" folder in the extensions folder) • Microsoft Dialog Library • Microsoft OLE Library This means that the following files can be "disabled." Note that with this setup, OLE, ODBC Databases, and Visual Basic will be inoperable: • Microsoft Office Manager • Office Manager Patch • Microsoft Dialog Library • Microsoft Find File Library • Microsoft Mail Library • Microsoft OLE Automation • Microsoft OLE Extension • Microsoft OLE Library • Microsoft Tool Editor Library • Visual Basic for Applications • ODBC Setup • ODBC Configuration Manager • ODBC Driver Manager • ODBC SQL Server ADSP NetLib • ODBC SQL Server Driver • ODBC SQL Server TCP/IP Netlib • ODBC SQL Server Setup • Q+E ODBC FoxPro Driver • Apple® Event Manager • MTExt (a font): supposedly there are actually two of these files, a suitcase and a postscript font. The font itself is usually found in the Extensions Folder. Personally, I only enable the following files, and have extensive functionality and no crashes: • Microsoft Dialog Library • Microsoft OLE Automation • Microsoft OLE Extension • Microsoft OLE Library • Visual Basic for Applications To run only Word 6 (no Excel), you only really need these two, although some of the advanced functions may not be fully functional: • Microsoft Dialog Library • Microsoft OLE Library
