Java синтаксическая ошибка в имени файла

Создаю проект в Eclipse IDE, создал class и file в одном и том же месте.
Описал как:

URL urlFnumZ = HelixAtlaskirov.class.getResource("FnumZ.txt");

Если запустить в Eclipse работает на ура, а после сборки jar когда заворачиваю в exe с помощью программы launch4j выдает ошибку:

Caused by: java.io.FileNotFoundException: file:C:GHelix-Lab.exe!atlaskirovhelixjfxFnumZ.txt (Синтаксическая ошибка в имени файла, имени папки или метке тома)

Так же пробовал описать как:

URL urlFnumZ = HelixAtlaskirov.class.getClassLoader().getResource("FnumZ.txt"); то же самое.

Решил тем что поменял метод чтения файла на:

InputStream urlFnumZ = HelixAtlaskirov.class.getResourceAsStream("FnumZ.txt");
Scanner fsNz = new Scanner(urlFnumZ);

This can occur when filename has timestamp with colons, eg. myfile_HH:mm:ss.csv Removing colons fixed the issue.

Try this, as it takes more care of adjusting directory separator characters in the path between targetPath and filename:

File targetFile = new File(targetPath, filename);

I just encountered the same problem. I think it has to something do with write access permission. I got the error while trying to write to c: but on changing to D: everything worked fine.
Apparently Java did not have permission to write to my System Drive (Running Windows 7 installed on C:)

Try to create the file in a different directory — e.g. «C:» after you made sure you have write access to that directory. If that works, the path name of the file is wrong.

Take a look at the comment in the Exception and try to vary all the elements in the path name of the file. Experiment. Draw conclusions.

Remove any special characters in the file/folder name in the complete path.

Do you check that the targetPath is a directory, or just that something exists with that name? (I know you say the user can copy it from the operating system, but maybe they’re typing something else).

Does targetPath end with a File.separator already?

(It would help if you could log and tell us what the value of targetPath and filename are on a failing case)

Maybe the problem is that it is copying the file over the network, to a shared drive? I think java can have problems when writing files using NFS when the path is something like mypcmyshared folder.

What is the path where this problem happens?

Try adding some logging to see exactly what is the name and path the file is trying to create, to ensure that the parent is well a directory.

In addition, you can also take a look at Channels instead of using a loop.

As I was not able to reproduce the error on my own machine or get hands on the machine of the user where the code failed I waited until now to declare an accepted answer.
I changed the code to the following:

File parentFolder = new File(targetPath);
... do some checks on parentFolder here ...
File targetFile = new File(parentFolder, filename);
targetFile.createNewFile();
fileInputStream = new FileInputStream(fileToCopy);
fileOutputStream = new FileOutputStream(targetFile);
byte[] buffer = new byte[64*1024];
int i = 0;
while((i = fileInputStream.read(buffer)) != -1) {
    fileOutputStream.write(buffer, 0, i);
}

After that it worked for the user reporting the problem.

So it seems Alexanders answer did the trick — although I actually use a slightly different constructor than he gave, but along the same lines.

I yet have to talk that user into helping me verifying that the code change fixed the error (instead of him doing something differently) by running the old version again and checking if it still fails.

btw. logging was in place and the logged path seemed ok — sorry for not mentioning that. I took that for granted and found it unnecessarily complicated the code in the question.

Thanks for the helpful answers.

FileUtils.copyFile(src,new File("C:\Users\daiva\eclipse-workspace\PracticeProgram\Screenshot\adi.png"));

Try to copy file like this.
