Answer 1

Based on comments above i made 2 different solutions. The solution for you right now would be no. 2

1. This one can search for a specific file based on multiple files in your path. It need some tweaking but can be used if you wanna check if a specific file exists with wildcard

2. This one evaluates to true if any wildcard file is found.

C# Code 1

Using System.IO:

string Filepath = Dts.Variables["User::Source"].Value.ToString();
            string WildCard = Dts.Variables["User::file"].Value.ToString(); // In Text form @"*.txt";
            string fullpath = Filepath + WildCard;

            //With for loop
            string txtFile = null;
            // Gets all files with wildcard
            string[] allfiles = Directory.GetFiles(Filepath, WildCard);
            
            //Loop through all files and set the filename in txtFile. Do whatever you want here
            foreach(string fileName in allfiles)
            {
                //Check if a file contains something, it could be a prefixed name you only want
                if(fileName.Contains("txt"))
                {
                    txtFile = fileName;
                    if(File.Exists(txtFile))
                    {
                        Dts.Variables["User::Exists"].Value = 1;
                    }
                }
            }

C# Code 2

 Using System.IO;
 Using System.Linq;

 string Filepath = Dts.Variables["User::Source"].Value.ToString();
            string WildCard = Dts.Variables["User::file"].Value.ToString(); //In text form "*.txt";
            string fullpath = Filepath + WildCard;

            //With bool
            bool exists = Directory.EnumerateFiles(Filepath, WildCard).Any();

            if(exists == true)
            {
                Dts.Variables["User::Exists"].Value = 1;
            }

              
            MessageBox.Show (Filepath);
            MessageBox.Show(Dts.Variables["Exists"].Value.ToString());
