Are you facing xcopy invalid number of parameters error while trying to copy a system file from one directory to another?
Here, I will discuss the issue based on a real-life problem taken from the community.
It works when one ran the below command-
xcopy X:\ “Y:\…\bin\9876543210\” /c /g /d /i /e /r /h /y
But it couldn’t work and released the message- ‘Invalid number of parameters’ when he ran the below command-
xcopy X:\ “Y:\…\bin\9876543210\” /c /g /d /i /e /r /h /y /exclude:”Y:\…\exclude.txt”
So, the question is, how can you solve the error?
Reason Behind the Error
Before jumping into the solution, I include the reason behind the error occurring. Here the ‘\exclude’ parameters are responsible for the error. However, the error is solvable.
What to Do With Xcopy Invalid Number of Parameters Error
You may try many fixes to resolve the error. Here I will include three fixes. You can try them for the related error discussed in this article. The fixes are-
- Fix 1: Use 8.3 Filename
- Fix 2: Use the SUBST Command
- Fix 3: Use the PUSHD Command
Fix 1: Use 8.3 Filename
You can use the 8.3 filenames for the system file you want to copy from one directory to another through the ‘xcopy’ command. The short 8.3 folder name might help you to recover from the discussed problem.
However, if it doesn’t, you can follow the next one.
Fix 2: Use the SUBST Command
The below command may relieve you from the error you face while running the ‘xcopy’ command. The process will create a drive alias for the troublesome path.
To do so, copy the below command and paste it into the Command Prompt window.
subst Q: “Y:\path with spaces”
xcopy X:\ “Y:\…\bin\9876543210\” /c /g /d /i /e /r /h /y /exclude:Q:exclude.txt
subst Q: /d
After that, hit the ‘enter’ key. If you still get the invalid message, you will have the last option to solve the error.
Fix 3: Use the PUSHD Command
As a last try, you can apply the below type command to resolve the error you have faced.
pushd “Y:\path with spaces”
xcopy X:\ “Y:\…\bin\9876543210\” /c /g /d /i /e /r /h /y /exclude:exclude.txt
In the end, hit the ‘enter’.
Hopefully, the xcopy command will work. Now, you can copy the system file from one directory to another without facing the xcopy invalid number of parameters error.
