  • Microsoft Windows for Workgroups 3.11

This article was previously published under Q107645


Windows for Workgroups version 3.11 caches disk writes by default when the 32-bit file system is enabled. This includes MS-DOS DoubleSpace 6.2 volumes; however, it does not include third-party disk-compression systems.


To disable write caching with the 32-bit file system, add the following line to the [386Enh] section of the SYSTEM.INI file:


where <drivelist> is the list of drives in which you want to disable write caching. (Do not use any delimiters or spaces.) For example, the line


would disable write caching on drives C, D, and F.

For more information about the 32-bit file system, query on the following words in the Microsoft Knowledge Base:

wfwg and vfat and 32-bit
