Hey Stefan, let's sort out this problem with launching your .bat files—your command syntax is the main culprit here, and we'll get it working in no time.

First: Correct the start Command Syntax #

Your original command Start C:>FileName.bat has a critical error: the > is a redirection operator in CMD, not part of the file path. That's why the command fails.

The proper syntax for launching a .bat file with start is:

start "" "Full\Path\To\Your\File.bat"

• The empty quotes "" are required because the first quoted argument in start is treated as the new command window's title. If you skip this and your file path has spaces, CMD will misinterpret the path as the title and fail to launch the file.
• Example: If your .bat file is directly in the C drive root, the command becomes:

  start "" "C:\FileName.bat"
  

Launching All 3 .bat Files at Once #

You have two easy ways to launch all three files simultaneously:

Option 1: Run Commands Directly in CMD #

Just execute three corrected start commands one after another in the command prompt:

start "" "C:\FirstFile.bat"
start "" "C:\SecondFile.bat"
start "" "C:\ThirdFile.bat"

Each command will open a new CMD window running the respective .bat file.

Option 2: Create a "Launcher" .bat File #

If you need to do this regularly, create a new .bat file (name it something like LaunchAllBats.bat) and paste the three start commands inside. Double-clicking this launcher file will automatically start all three target .bat files.

Troubleshooting Other Potential Issues #

If you still run into problems after fixing the syntax, check these common pitfalls:

• Incorrect File Path: Double-check that the full path to each .bat file is spelled correctly (no typos, missing folders, or wrong drive letters).
• Permissions: If your .bat files require admin access, right-click CMD and select "Run as administrator" before executing the commands. Alternatively, use the runas parameter for elevated access:

  start "" runas /user:Administrator "C:\FileName.bat"
  

  (You'll need to enter the administrator password when prompted.)
• Antivirus Interference: Some antivirus tools block .bat files by default. Try temporarily disabling your antivirus to test, or add your .bat files to the antivirus's trusted list.
