Always make file paths, temporary directories, and resource locations configurable with reasonable defaults instead of hard-coding them. Users may have specific environment requirements such as using SSDs instead of system drives or working with constrained environments like Spring Boot. Implement a hierarchical approach to resource configuration: 1. Allow explicit configuration through system properties or configuration files 2. Provide fallback to environment-specific defaults when explicit configuration isn't available 3. Document all configurable paths and their default values For example, instead of: ```java File holder = File.createTempFile("FileChunksTracker", "Message"); ``` Use a configurable approach: ```java // Define in a centralized properties class public static final String FILE_STORAGE_DIR_PROPERTY = "org.nd4j.tempfiles.directory"; // Use in implementation String tempDir = System.getProperty(FILE_STORAGE_DIR_PROPERTY, System.getProperty("java.io.tmpdir")); File storageDir = new File(tempDir); if (!storageDir.exists()) { storageDir.mkdirs(); } File holder = File.createTempFile("FileChunksTracker", "Message", storageDir); ``` This practice improves flexibility across different deployment environments and facilitates troubleshooting when resource loading issues occur.
