As I wrote, the AppData directory and EE workspace location are absolutely correct and always working. %APPDATA% points to "D:\Documents and Settings\<username>\Application Data\", EmEditor workspace storage is located in "D:\Documents and Settings\<username>\Local Settings\Application Data\Emurasoft\EmEditor\Workspace\", it is saved when I call Save Workspace, and restored when I call Restore Workspace command.

But sometimes, for unknown reason and unknown purpose, at some unknown moment of time in the drive root an empty "D:\Emurasoft\EmEditor\Workspace\" directory suddenly appears. I can remove it, then work for several days or even weeks without appearing of this directory, even though I use various EE functions (including saving/restoring workspaces and files). But some day it appears again.
