A name, specified by either the user, programmer, or software, comprised of alphanumeric characters, to identify a file and its contents. Different programs and operating systems have their own naming rules. A basic MS-DOS filename contains up to eight letters or numbers, followed by the file’s three- or four-letter file extension, in this format: "filename.ext". Windows95 and 98 allow users to specify a filename of up to 255 characters.
A Filename is any legal name you give to a file. In the CLI for example, it can consist of up to thirty characters except slash (/) and colon (:), both of which mean special things to AmigaDOS. To keep life simple, it's a good idea to avoid imbedded spaces in filenames, (though it can be done by enclosing the full pathname/filename in double-quotes), and you should try to make filenames sufficiently informative, so that you can recognise what they mean at a later time. Filename extensions or suffixes, such as ".ltr" (for a letter), or ".hr" (for a DPaint hi-res image), are useful, while in certain programs they are essential such as .doc (for a document in Scribble). You can put as many full stops as you like in a filename. However, be warned that if you want to output a file which you later want to read on an MS-DOS machine, the filename must be less than 8 characters unless you include separators (`.'), e.g. example.doc.
A unique name for a file. MS-DOS filenames can be from one to eight characters in length and can be followed by a filename extension consisting of a period (.) and one to three characters. See also filename extension.
a one-to-eight character alphanumeric field, comprised of A through Z, 0 through 9, and special characters $ # @ + - (hyphen) : (colon) _ (underscore), that is part of the CMS file identifier and serves to identify the file for the user.
This is a key developed by using a combination of the decedent's name and the year in which the inventory was taken, ordered, or recorded, in that order. The eight character field is used to invisibly link the Main Inventory Table with the Detail Inventory Table.
The name of a file. All files have names. Different operating systems impose different restrictions on filenames. Most operating systems, for example, prohibit use of certain characters in a filename and impose a limit on the length of a filename. In addition, many systems, including DOS and UNIX, allow a filename extension that consists of one or more characters following the proper filename. The filename extension should indicate what type of file it is. However, users often change filename extensions to evade firewall restrictions or for other reasons. Therefore, file types must be identified at a binary level rather than relying on file extensions.
This is the name under which the file is stored. You can use any name -- even long ones with blank spaces. Sometimes filenames contain a period followed by a three-character extension. For example, Word files contain the extension .doc while .xls is attached to Excel filenames. If a name contains the extension .exe or .com, then the file is probably a program.
The name that identifies the file within its directory. It comprises everything from the character following the last backslash to the character preceding the final period (if there is one). See also: path
the field of a fileid that identifies a file to the user under CMS. A filename contains from one to eight alphanumeric characters chosen from the following: A through Z, 0 through 9, and the special characters $, #, @, +, -, :, and _.
a handle, not necessarily ever directly represented as an object, that can be used to refer to a file in a file system. Pathnames and namestrings are two kinds of objects that substitute for filenames in Common Lisp.
A filename is a special kind of string used to uniquely identify a file stored on the file system of a computer. Depending on the operating system, such a name may also identify a directory. Different operating systems impose different restrictions regarding length and allowed characters on filenames.
