Creating a Filename zUp to 14 characters long, may include: y1.{a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z, A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z} y2.{0, 1, 2, 3, 4, 5, 6, 7, 8, 9} y3.{period (.), underscore(_), comma(,)}

Watch Out! Part I zDo not name a file period (.) or period period (..) zAvoid naming a file the same as a Unix command zUnix is case sensitive, avoid upper case

Watch Out! Part II zUse widely known file extensions (eg. txt or doc) yFile extensions not obligatory zStart a file with a letter or a number yPeriod (.) makes it a hidden file
