Hello,   On click of a button I need to implement downloading of List of FileDocuments to specific path (example: C:\New folder).  I tried it with File from file document java action from community commons and it works when I run the project locally but it does not work when I deploy it on Acceptance. Error that occurs is: Caused by: com.mendix.modules.microflowengine.MicroflowException: com.mendix.systemwideinterfaces.MendixRuntimeException: java.io.FileNotFoundException: C:\New folder\testdocument.docx (Permission denied)   I also tried with custom Java action and in this case it also works locally but on environment I get the error: java.io.FileNotFoundException C:\New folder/F_5531512519_-.docx (No such file or directory)   Java action: // This file was generated by Mendix Studio Pro. // // WARNING: Only the following code will be retained when actions are regenerated: // - the import list // - the code between BEGIN USER CODE and END USER CODE // - the code between BEGIN EXTRA CODE and END EXTRA CODE // Other code you write will be lost the next time you deploy the project. // Special characters, e.g., é, ö, à, etc. are supported in comments. package extendedworkbench.actions; import com.mendix.systemwideinterfaces.core.IContext; import com.mendix.webui.CustomJavaAction; import com.mendix.systemwideinterfaces.core.IMendixObject; import com.mendix.core.Core; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.ByteArrayOutputStream; import java.util.List; import java.util.Optional; import java.util.Collections; import java.util.stream.Collectors; public class SaveDocumentsToFolder extends CustomJavaAction<java.lang.Void> { private java.util.List<IMendixObject> __DocumentsList; private java.util.List<system.proxies.FileDocument> DocumentsList; private java.lang.String Path; public SaveDocumentsToFolder(IContext context, java.util.List<IMendixObject> DocumentsList, java.lang.String Path) { super(context); this.__DocumentsList = DocumentsList; this.Path = Path; } @java.lang.Override public java.lang.Void executeAction() throws Exception { this.DocumentsList = java.util.Optional.ofNullable(this.__DocumentsList) .orElse(java.util.Collections.emptyList()) .stream() .map(__DocumentsListElement -> system.proxies.FileDocument.initialize(getContext(), __DocumentsListElement)) .collect(java.util.stream.Collectors.toList()); // BEGIN USER CODE for (system.proxies.FileDocument document : DocumentsList) { String fileName = document.getName(); byte[] fileContent = getFileContent(document.getMendixObject()); saveFile(Path, fileName, fileContent); } return null; // END USER CODE } /** * Returns a string representation of this action * @return a string representation of this action */ @java.lang.Override public java.lang.String toString() { return "SaveDocumentsToFolder"; } // BEGIN EXTRA CODE private byte[] getFileContent(IMendixObject fileDocument) throws IOException { try (InputStream inputStream = Core.getFileDocumentContent(getContext(), fileDocument); ByteArrayOutputStream buffer = new ByteArrayOutputStream()) { int nRead; byte[] data = new byte[1024]; while ((nRead = inputStream.read(data, 0, data.length)) != -1) { buffer.write(data, 0, nRead); } buffer.flush(); return buffer.toByteArray(); } } private void saveFile(String folderPath, String fileName, byte[] content) throws IOException { File file = new File(folderPath + File.separator + fileName); try (FileOutputStream fos = new FileOutputStream(file)) { fos.write(content); } } // END EXTRA CODE }   Any idea on how to make it work?   Regards, Stefan
