@DRIVE[filename]:  Returns the drive of filename. If the filename parameter doesn't contain a drive specification, @DRIVE will expand filename before the drive is extracted.

 

filename must be in quotes if it contains white space or special characters.

 

If the path is a UNC, @DRIVE will return the computer name + sharename.

 

Examples:

 

echo @drive["c:\program files\xyz.abc"]

c:

 

echo "%@drive[\\system1\d_drive\myfile]"

\\system1\d_drive
