!homedir
The !homedir extension sets the default directory used by the symbol server and the source server.
!homedir Directory
!homedir
Parameters
Directory
Specifies the new directory to use as the home directory.
DLL
Dbghelp.dll
Remarks
If the !homedir extension is used with no argument, the current home directory is displayed.
The cache for a source server is located in the src subdirectory of the home directory. The downstream store for a symbol server defaults to the sym subdirectory of the home directory, unless a different location is specified.
When WinDbg is started, the home directory is the directory where Debugging Tools for Windows was installed. The !homedir extension can be used to change this value.
