What launch arguments do and how to add them
Launch arguments are text commands you add when starting a program to change how it runs. Instead of double-clicking an EXE file normally, you tell it to start with specific settings — like opening a file directly, running in a certain mode, or skipping the splash screen. You add these arguments through a shortcut, the command line, or a batch file, depending on what you need the program to do.
The program itself has to support the arguments you want to use. Not every EXE accepts custom launch arguments, and the ones that do vary widely in what they accept. You will need to check the program's documentation or help menu to see what arguments it recognizes.
Key Takeaways
- Launch arguments are text commands added when starting a program to change its behavior, and you add them through a shortcut, command line, or batch file.
- The program must support the specific arguments you want to use — check its documentation or help menu to see what it accepts.
- Creating a shortcut is the easiest method for regular use, since you can save the arguments in the shortcut properties and click it like normal.
- Command line and batch files work for testing arguments quickly or running programs with different settings each time.
- Arguments are separated by spaces and often use hyphens or forward slashes, but the exact format depends on the program.
Adding arguments through a shortcut
Creating a shortcut is the simplest way to use launch arguments regularly. Right-click on the EXE file, select Send to, then choose Desktop (create shortcut). A shortcut icon will appear on your desktop.
Right-click the shortcut and select Properties. In the Target field, you will see the full path to the EXE in quotation marks. After the closing quotation mark, add a space and then type your arguments. For example, if the program is C:\Program Files\MyApp\program.exe and you want to add the argument -windowed, the Target field should read: "C:\Program Files\MyApp\program.exe" -windowed. Click Apply, then OK. Now when you double-click the shortcut, it will launch with those arguments.
You can create multiple shortcuts with different arguments for different purposes. Name each one clearly so you remember what it does — for example, "MyApp Windowed" or "MyApp Debug Mode".
Using the command line to test arguments
The command line is useful for testing arguments before you save them in a shortcut. Open Command Prompt by pressing Windows key + R, typing cmd, and pressing Enter. Navigate to the folder where the EXE is located using the cd command. For example, type cd C:\Program Files\MyApp and press Enter.
Then type the program name followed by your arguments. If the program is called program.exe and you want to use the argument -debug, type program.exe -debug and press Enter. The program will launch with that argument. If it does not work, you will usually see an error message that tells you the argument is not recognized or the format is wrong.
Command line testing lets you try different arguments quickly without creating a shortcut each time. Once you find the combination that works, you can save it in a shortcut or batch file.
Creating a batch file for multiple arguments or repeated use
A batch file is a text file that runs commands automatically. It is useful if you need to launch a program with arguments regularly, or if you want to run the same program with different arguments at different times. Open Notepad, type the command you want to run, and save it with a .bat extension instead of .txt.
For example, if you want to launch program.exe from the folder C:\Program Files\MyApp with the argument -fullscreen, your batch file should contain: cd C:\Program Files\MyApp on the first line, then program.exe -fullscreen on the second line. Save it as launch.bat. Double-click the batch file to run it, and the program will launch with those arguments.
You can also add multiple commands to a batch file. For instance, you could launch the program, wait a few seconds, then launch it again with different arguments. Each command goes on its own line.
Understanding argument format and syntax
Arguments usually start with a hyphen (-) or forward slash (/), followed by the argument name. Some arguments take a value — for example, -resolution 1920x1080 sets the resolution to 1920 by 1080. Arguments are separated by spaces, and if an argument value contains spaces, wrap it in quotation marks.
The exact format depends on the program. Some use -argument, others use --argument (two hyphens), and some use /argument. Check the program's documentation or run it with -help or --help to see what arguments it supports and how to format them. Many programs will display a list of available arguments and examples if you use the help flag.
Common arguments across many programs include -help (shows available arguments), -version (shows the program version), and -config (points to a configuration file). Beyond that, arguments are specific to each program.
Finding what arguments a program accepts
The program's documentation is the best source. Check the official website, user manual, or help section. Many programs also display available arguments if you run them with -help, --help, /?, or -h from the command line.
If the program has no built-in help, search the program name plus "launch arguments" or "command line arguments" online. Developer forums, GitHub repositories, and community wikis often list arguments that users have discovered. Be aware that arguments can change between versions, so note which version of the program you are using when you search.
Some programs store their arguments in configuration files instead of accepting them at launch. In that case, you would edit the configuration file directly rather than adding arguments to the shortcut or command line.
Troubleshooting when arguments do not work
If the program launches but ignores your arguments, the most common causes are incorrect spelling, wrong format, or the program does not support that argument. Double-check the spelling and format against the documentation. Make sure there is a space between the EXE path and the first argument, and between each argument.
If the program does not launch at all, the path to the EXE may be wrong. In the shortcut properties, make sure the path is in quotation marks and points to the correct file. You can also test the path by opening File Explorer, navigating to the folder, and confirming the EXE is there.
Some programs require administrator privileges to run with certain arguments. If you think this might be the issue, right-click the shortcut, select Properties, go to the Advanced button, and check Run as administrator. Then click OK and try again.
Frequently Asked Questions
Do all EXE files accept launch arguments?
No. The program has to be written to accept them. Older programs and simple utilities often do not support launch arguments at all. The only way to know is to check the documentation or try running it with -help to see if it responds.
Can I use launch arguments with programs installed from the Microsoft Store?
It depends on the program. Store apps run in a sandboxed environment, which can restrict how they accept arguments. Traditional desktop programs installed from the Store usually work fine with launch arguments, but some may not. Test it with the command line first to see if the program responds.
What is the difference between a hyphen and a forward slash in arguments?
Different programs use different conventions. Some accept both, some only one. Check the program's documentation to see which format it expects. If one does not work, try the other.
Can I save multiple sets of arguments in one shortcut?
No, a shortcut runs one set of arguments each time. If you need to run the program with different arguments at different times, create multiple shortcuts or use a batch file that lets you choose which arguments to use.
Will adding arguments slow down the program or cause problems?
No, as long as the arguments are valid and the program supports them. Invalid arguments are usually ignored or cause an error message, but they will not damage the program or your system. If you are unsure, test the arguments on a copy of the program first.
