ToFileName

ToFileName["directory", "name"] assembles a full file name from a directory name and a file name.

• ToFileName[{dir1, dir2, ...}, name] assembles a full file name from a hierarchy of directory names.
• ToFileName[{dir1, dir2, ...}] assembles a single directory name from a hierarchy of directory names.

Examples

Create a file path:

ToFileName["/home/user", "file.txt"]

Build from directory hierarchy:

ToFileName[{"home", "user", "documents"}, "report.pdf"]
