File Directory in C#

To call Directory.GetFiles() with multiple filters, you can use the overload of the method that takes a search pattern as a parameter. The search pattern can contain multiple filters separated by the pipe (|) character. Here is an example that searches for files with a .txt or .docx extension in the specified directory:

string[] files = Directory.GetFiles(@"C:\MyFolder", "*.txt|*.docx");

To get the full path directory from a filename, you can use the Path.GetDirectoryName() method. This method returns the directory information for the specified path without the file name.

string fullPath = @"C:\MyFolder\myfile.txt";
string directory = Path.GetDirectoryName(fullPath); // Returns "C:\MyFolder"

To get the folder name from a full path filename, you can use the Path.GetFileName() method. This method returns the file name and extension of the specified path string.

string fullPath = @"C:\MyFolder\myfile.txt";
string fileName = Path.GetFileName(fullPath); // Returns "myfile.txt"
string folderName = Path.GetFileName(Path.GetDirectoryName(fullPath)); // Returns "MyFolder"

To delete all files and folders in a directory, you can use the Directory.Delete() method with the true option to delete all files and folders recursively. Here is an example:

string directoryPath = @"C:\MyFolder";
Directory.Delete(directoryPath, true);

To delete a directory with read-only files, you must first remove the read-only attribute from the files before you can delete them. You can do this using the File.SetAttributes() method with the FileAttributes.Normal option to remove the read-only attribute. Here is an example:

string directoryPath = @"C:\MyFolder";
foreach (string file in Directory.GetFiles(directoryPath, "*", SearchOption.AllDirectories))
{
    File.SetAttributes(file, FileAttributes.Normal);
}
Directory.Delete(directoryPath, true);

To delete files older than 6 months old in a directory, you can use the Directory.GetFiles() method to get all the files in the directory, and then use the File.GetLastWriteTime() method to check the last write time of each file. You can then use the File.Delete() method to delete the files that are older than 6 months. Here is an example:

string directoryPath = @"C:\MyFolder";
DateTime sixMonthsAgo = DateTime.Now.AddMonths(-6);
foreach (string file in Directory.GetFiles(directoryPath))
{
    if (File.GetLastWriteTime(file) < sixMonthsAgo)
    {
        File.Delete(file);
    }
}
