Data Handling
Once you have your computer running, you will start to generate data of your own. This data will be
stored in files (distinct collections of related data stored in a single format). You provide names for
those files when you save them from within the application that has been used to create them.
Windows 95 is capable of supporting long files names so that you can name a file running in a
Windows 95 application with a good, descriptive file name (for example, "John Smith financial records
for May 1996"). Programs which are not fully compatible with Windows 95 (DOS programs or
Windows 3.x programs) may be restricted to the older DOS convention of 8 characters and a three
character extension after a period (for example, jsmith96.fin).
Windows 95 makes use of the extensions to track what programs are associated with what extensions.
Your software will usually assign an extension to the long file name when you save, but you can
choose the extension yourself if you would prefer. The extensions allows Windows 95 to know what
application to launch when a document is selected for opening. Windows 95 does not typically display
those extensions i n
Explorer
or
My Computer
(since it uses icons for those files that indicate the
program with which they are associated), but it can be made to do so. Check the Windows 95
documentation for instructions on how to turn on that function.
OLE (object linking and embedding) is a built-in function of Windows 95 and of many applications
that will run under Windows 95. OLE allows you to create documents which are, in fact, compositions
of multiple files in multiple applications. Thus, you could write a report in a word processor that
would include a set of data from a spreadsheet and a graph from a presentation graphics program and
a picture from an image editing program. This single document would be edited by using the programs
to edit the individual components without you having to move from program to [XP5 Pro 2.7]
program (OLE keeps track of what program needs to be used for editing a certain part of a
document).
Thus your data is stored in files and/or as documents. Your applications and Windows 95 should do
all the keeping track of the documents, allowing you to concentrate on creating them.
[Sidebar: Eyeball icon: You should save your files often when you are working (about every 15
minutes or so). This will prevent you losing hours of work that has not been saved. You can also use
autosave functions in your software for this purpose.]
Once you have created files or documents, you can make copies of them, rename them, move them
around, or do many other things with them. You can also delete them when they are no longer
necessary.
Fortunately, a file that has been deleted can usually be restored. If you have used the Recycle program
in Windows 95, the deleted files will be stored there (until the bin is emptied). You can see the
Windows 95 documentation for information on how to use the Recycle program. Even a file that has
been "deleted" is usually recoverable, if you act quickly. When the computer deletes a program, it does
not immediately delete it. It marks that area of the disk as available for use. As you store more data,
that area might be overwritten (where a file is stored is random). If not much data has been stored
