That depends upon the Tcl/Tk implementation. For a native Windows
Tcl/Tk implementation, you would have to use c:\moritz. The /c/moritz
syntax is part of MinGW/Cygwin; it isn't valid within Windows itself.

Probably the safest solution is to use Tcl's "file" command to manage
filenames, rather than trying to do it manually using string
operations. The following sub-commands appear relevant.
file dirname name
file extension name
file join name ?name ...?
file nativename name
file normalize name
file pathtype name
file rootname name
file separator ?name?
file split name
file tail name
1. While most Windows API calls accept both '\' and '/', most
console-mode commands only accept '\', as '/' is used for switches
(which needn't be preceded by a space; "dir foo/w" is equivalent to
"dir foo /w" or "dir /w foo"). You probably need to use
"file nativename" for any filenames passed to Tcl's "exec" command.
2. Don't forget about UNC paths: \\server\share\path\to\file.txt
3. There is some additional information in the filename(n) manpage.
