You can retrieve information about devices, directories, and files with the functions listed below. File names can be long file names or UNC file names. A forward slash in a path name is treated as a backslash. All path names can contain drive specifications.

Standard Fortran 90 provides the INQUIRE statement, which returns detailed file information either by file name or unit number. Use INQUIRE as an equivalent to FSTAT, LSTAT or STAT. LSTAT and STAT return the same information; STAT is the preferred function.
