File Management

managing files and folders
correctly prevents wasted time,
frustration and errors.

proper file management begins
with using file naming conventions
and good organization.
guidelines for naming files and
folders:

Use short, simple file and folder names

Use file and folder names that describe the content accurately.

Use underscores instead of spaces in file names. For example:
descriptive_essay

Use all lowercase letters in file names.

Avoid using characters such as: ! # $ % @ ^ ` ~ + ; = in file and folder
names. Some systems do not allow you to use characters in file and
folder names, and will not accept them.

A file extension is the suffix at the end of a filename that indicates
