Filespecs

A filespec, short for file specification, is a string of characters that uniquely identifies a file within a file system. It provides information about the file's location and name, allowing operating systems and applications to find and access it. The structure of a filespec can vary depending on the operating system and the specific file system being used.

Commonly, a filespec includes the drive or volume where the file is stored, followed by a sequence of directory names that lead to the file. Each directory name is separated by a specific delimiter character, such as a forward slash (/) in Unix-like systems or a backslash (\) in Windows. Finally, the filespec includes the actual name of the file, which often has an extension indicating its type.

For example, a typical Windows filespec might look like C:\Users\Documents\report.docx, where "C:" is the drive, "Users" and "Documents" are directories, and "report.docx" is the filename with its extension. In contrast, a Unix-like filespec might appear as /home/user/documents/report.odt, using forward slashes as separators.

Filespecs are fundamental to file system operations. They are used in commands for opening, saving, copying, moving, and deleting files. Applications rely on correct filespecs to manage data and resources. Understanding filespecs is crucial for anyone working with computer files and operating systems, as it forms the basis for how files are organized and accessed.
