pathhandling
Path handling refers to the set of techniques and APIs used to manipulate path strings in software, including filesystem paths and URL paths. It encompasses parsing, joining, normalizing, resolving, and validating paths, as well as querying components such as directory, file name, and extension.
Common path types include filesystem paths, which identify locations on a storage volume, and URL paths, which
Core operations include joining multiple path segments, normalizing to remove redundant separators and resolve special segments
Platform differences: POSIX systems use forward slashes and case-sensitive paths; Windows uses backslashes and may treat
APIs: languages offer dedicated path libraries—Python's pathlib and os.path, Java's NIO Paths, Node.js path, Go path/filepath,
Security and correctness: improper path handling can lead to directory traversal vulnerabilities or misinterpretation of relative
