yeah i got it i had to disable some command extensions

cmd eff

thx for the link someone posted here www.microsoft.com i found it there

cmd eff

When you disable command extensions, chdir does not treat white spaces as delimiters. As a result, you can change to a subdirectory name that contains a white space without having to surround [Path] in quotation marks. For example, the following path changes to the \Start menu subdirectory:

cd \winnt\profiles\username\programs\start menu

thx for help
