Gr 10 4.2 – FILE MANAGEMENT Flashcards
Audio Files
Files that contain sound or music. Common audio file
formats include MP3, MP4, WAV, CDA, WMA.
Compressed files
A file format used for files that contain files or folders in
compressed format to save space. Typical file extensions
include rar and zip.
Data hierarchy
Refers to the two levels of data storage – the lower bits and
bytes level and the higher levels of files, databases and data
warehouses.
Data warehouse
A data warehouse is a vast collection of data fathered from a
variety of databases and other data sources. It is specifically
designed to determine trends and patters within the data
and it is designed for reporting and querying.
DLL Files
DLL or Dynamic Link Libraries are files that contain code or
routines that can be called and used by programs.
File
A file is a collection of data or information that is stored on a
computer under a single name. They are represented as
icons on the computer.
File extension
This set of characters (usually 3-5) is added to the end of a
file name and it identifies the type of file e.g. docx is the file
extension of a Microsoft Word file.
File format
How data is structured or organised within a file. Each
program has its own file structure for its files. Some
programs can interpret or read files that have a different file
structure to the one they use.
File manager
A utility program like Windows Explorer that comes as part
of the operating system. It allows the user to manage their
files and folders.
File name
Name given to a file followed by a full stop and the file
extension e.g. MyFile. docx
File naming conventions
Rules and restrictions that the operating system places on
how a file can be named. Organisations or individuals might
also choose to name their files according to a fixed format
that they choose.
Folder
A folder is a storage place or container in which you can
store files or more folders on disk.
Font files
Files containing fonts that can be used by programs on the
computer where the fonts are installed. They typically have
a file extension of TTF or OTF.
Graphics files
Files that contain images or graphics. Common graphics
formats include JPEG, BMP, GIF, WMF, TIF, PNG.
Path
The ‘sequence’ of folders that lead to the location of a
specific file. The backslash character is used to separate the
‘list’ of folders in the path e.g. D:\Documents\Invoices\
PDF Files
Portable Document Format files are used to distribute
document files, as they do not require the program in which
the document was created to be installed to read. You just
need a free utility program called Adobe Reader to read it.
Plain text files
A text file that contains lines of plain text. The file extension
.txt is associated with text files. Text files can be opened by
any word processing application or simple text editing
utilities such as WordPad and Notepad.
Program files
These are actual programs, not data files, that run (execute)
when opened. They normally have a .COM or .EXE file
extension.
Programming languages
Programs such as Delphi, Java and C# that allow one to
construct and specify a set of programming instructions or
source code.
Rich text files
Rich Text format files support ‘rich text’, which includes text
formatting, such as bold and italics, fonts and font sizes,
page setup and tab settings and even images.
Wildcards
Characters that represent one or more characters. For
example Windows allows us to use an asterisk (*) to
represent any number of characters or a question mark (?)
to represent one single character when searching for files or
folders.
