AL code for show all file of the sharing directory

 To show all files in a sharing directory using AL code in Microsoft Dynamics 365 Business Central, you can utilize the `FileManagement` codeunit to retrieve a list of files from the directory. Here's an example:

```AL

PROCEDURE ShowFilesInDirectory@1()

VAR

  FileManagement@1: Codeunit 419;

  DirectoryPath@2: Text[250];

  Files@3: List of [Text[250]];

  FilePath@4: Text[250];

BEGIN

  // Shared path of the directory

  DirectoryPath := '\\server\share\directory\';

  

  // Get a list of all files in the directory

  FileManagement.GetFilesFromDirectory(DirectoryPath, '', Files);

  

  FOR EACH FilePath IN Files DO BEGIN

    MESSAGE('File: ' + FilePath);

  END;

END;

```

In this example, we use the `FileManagement` codeunit to perform file-related operations. First, we set the `DirectoryPath` variable to the shared path of the directory containing the files you want to show.

The `GetFilesFromDirectory` function of the `FileManagement` codeunit retrieves a list of all files in the specified directory. The retrieved file paths are stored in the `Files` variable.

We then iterate over each file path in the `Files` list using a `FOR EACH` loop. For each file, we display a message box showing the file path using the `MESSAGE` statement.

Adjust the code according to your needs, and make sure that the shared directory is accessible from the server running Business Central and that the necessary permissions are set for accessing the shared folder and files within it.
