PUSHD [path | ..]

path

Specifies the directory to make the current directory.

If Command Extensions are enabled the PUSHD command accepts network paths in addition to the normal drive letter and path.
If a network path is specified, PUSHD will create a temporary drive letter that points to that specified network resource and
then change the current drive and directory, using the newly defined drive letter. Temporary drive letters are allocated from Z: on down, using the first unused drive letter found.
