Long fully qualified path of parent folder I ran some tests in Windows 7 and found the following parameters for file associations: Parameter To get the long file name, use "%L" instead of "%1". In Windows 9x through 2000 (and possibly XP) this would evaluate to the short notation of the fully qualified path of the file of type FileType. ![]() Often we find "%1" in the commands associated with file types ( HKEY_CLASSES_ROOT\ FileType\shell\open\command). "C:\Program Files\Microsoft Office\Office12\WINWORD.EXE" /n /dde for HKEY_CLASSES_ROOT\Word.Document.12\shell\open\command). In HKEY_CLASSES_ROOT\ FileType\shell\open\command the "File Open" command is stored (e.g. The details for the specified file type are also stored in the HKEY_CLASSES_ROOT hive under HKEY_CLASSES_ROOT\ FileType (e.g. Word.Document.12 for HKEY_CLASSES_ROOT\.docx). The HKEY_CLASSES_ROOT\.ext entry (as created by the ASSOC command) points to the file type (e.g. The file associations for non-executable files are stored in the registry in the HKEY_CLASSES_ROOT hive. If done from the command line, it is the equivalent to doing a CD /D to that path. When executing a command, if there is no match on any extension, then looks to see if the name, without any extension, matches a directory name and if it does, the START command launches the Explorer on that path. Notice the syntax is the same as the PATH variable, with semicolons separating the different elements. The default value for the PATHEXT variable is. When executing a command line whose first token does NOT contain an extension, then CMD.EXE uses the value of the PATHEXT environment variable to determine which extensions to look for and in what order. When executing a command line whose first token is CMD without an extension or path qualifier, then replaces CMD with the value of the COMSPEC variable, thus avoiding picking up random versions of CMD.EXE when you least expect them. This new behavior does NOT occur if executing within a command script. When executing an application that is a 32-bit GUI application, CMD.EXE does not wait for the application to terminate before returning to the command prompt. See the ASSOC and FTYPE commands for how to create these associations from within a command script. WORD.DOC would launch the application associated with the. Non-executable files may be invoked through their file association just by typing the name of the file as a command. If Command Extensions are enabled, external command invocation through the command line or the START command changes as follows: These are the parameters passed to the command/program If it is not an internal cmd command or batch file then it is a program and will run as either a windowed application or a console application. This means that the window will remain after the command has been run. If it is an internal cmd command or a batch file then the command processor is run with the /K switch to cmd.exe. Unless the application enables ˆC processing, ˆBreak is the only way to interrupt the application Start application without creating a new window. Start application and wait for it to terminate Start application in the REALTIME priority class Start application in the HIGH priority class ![]() Start application in the NORMAL priority class Start application in the IDLE priority class Start 16-bit Windows program in shared memory space Start 16-bit Windows program in separate memory space The new environment will be the original environment passed to the cmd.exe and not the current environment. Starts a separate window to run a specified program or command. The START command: Windows NT 4/Windows 2000 Syntax Read my SETLOCAL page if you intend to use SETLOCAL extension switches. Likewise, you may disable command extensions using SETLOCAL DISABLEEXTENSIONS or CMD /Y. However, to be absolutely sure that they are, either use SETLOCAL ENABLEEXTENSIONS within your NT shell scripts (batch files) or execute those scripts using CMD /X.
