A file name is what a file is called. A file extension defines what type of file it is. (Text file, HTML file, executable, etc.)

Use the file type test:

if [ -d $file ]; then

echo $file is a directory

elif [ -f $file ]; then

echo $file is a file

else

echo $file is not a directory or a file

fi

Active file: An active file is where you use a file quite frequently.

Inactive file: A file that you use but not as frequently.

Dead file: A dead file is where you don't use the file at all and is stored in your archives

A location of a file is specified by its File Path.
