Apache Commons IO is a mature Java utility library that simplifies input/output operations with helper classes like IOUtils, FileUtils, and FilenameUtils for streams, files, and filenames. It also provides file monitoring, file filters, comparators, and NIO Path extensions.

Use cases

• copy files and directories in java
• read a file into a string or byte array
• monitor a directory for file changes
• manipulate file names and extensions cross-platform
• filter and sort files in a directory
• delete a directory tree recursively
• compare files by name, size, or extension

When to choose

• you are on the JVM and want battle-tested IO utilities instead of hand-rolling stream and file handling
• you need file system monitoring, file filters, or filename manipulation in Java 8+
• you want a small, permissively licensed (Apache-2.0) dependency with long-term maintenance

When to avoid

• you are not on the JVM
• you need async or reactive IO abstractions rather than blocking stream/file utilities
• you want a full filesystem abstraction or virtual filesystem - look at other libraries
