Hi @דני שטרית , Welcome to Microsoft Q&A,

Please don't use screenshots, give minimal reproduction code. What error message did you encounter? I don't quite understand what you want to do at the moment.

OK. I tried to write code but I blocked.

i have app, i check files, and keep their path in concat List<string>

then i copy then to ArgumentList of processinfo.

when i select long file i provide before or alot of files the process not fire.

Hi @דני שטרית ,

So you currently have no code to reproduce? And it doesn't give any error message? The information I got so far is that the path you are trying to add argument to is too long and cannot run. Can you use environment variables or relative paths to replace this too long path, or split the too long argument?

When i check the app of the process this long file upload but when i pass it throgh process is not work. The long path is in the root of D drive.

What do you mean relative paths? can you supply code?

Regarding error how i get the error message from process, exit code?

Do you mean the process works when using files with short names? This can determine your problem and whether the current user has permission to operate.

Yes works with short names and my user has permission.

what with long file name or long list ?

Why is not working with long file name or long list of

ArgumentList of processinfo

What about this code?

// List of file names (potentially long)
        string[] fileNames = { "File1WithALongName.txt", "File2WithAVeryLongName.txt", "File3WithAnotherLongName.txt" };

        // Construct a single string containing all file names separated by spaces
        string fileNamesString = string.Join(" ", fileNames.Select(fileName => $"\"{fileName}\""));

        // Set the current directory of the process to a shorter path
        Environment.CurrentDirectory = @"C:\";

Two problems:

File name can be long as I gave you in other post.

string has a limit on its long.

I was using ? as join seprator since is not valid charcter of file name. since I need to split it in target app.

I can use argumentList with files name + current directory to limit the problem is it ?

I did and it works better now.

foreach (var item in concatFiles)

{

psi.ArgumentList.Add(new FileInfo(item).Name);

}

psi.WorkingDirectory = tempFolderFullPath;

In debug I got:

System.ComponentModel.Win32Exception: 'An error occurred trying to start process 'C:\GssdDesktopClient\ExternalApps\BurnMedia\BurnMedia.exe' with working directory 'C:\GssdDesktopClient\ExternalApps\CopyTempFolder'. The parameter is incorrect.'

Argument list is limited instead of passing all the file path or name in relative way I pass the path where all files reside and do Directory.getfiles to get all pathes.

If large quantities don't work, then you can choose to split it up and do it in groups. Whether the path length can be read also depends on the computer, you need to try to shorten it.

How is can be done in group?

The problem solved.

Instead of passing in ArgumentList all files names in relative way.

I passed the path where are located this file in ArgumentList.

And in the process inside, i used Directory.Getfiles to get all files.

Thanks you very much.
