A:command
MS-DOS finds and runs the command if it is in the current directory on the diskette in drive A.
You can use drive identifiers in other ways. For example, to copy a file from drive C to drive
A using MS-DOS at the system prompt, type:
COPY C:sourcefile A:targetfile
MS-DOS copies the sourcefile (the file you want to copy) from the hard disk to the diskette
in drive A and names it targetfile (any name you choose to type in ). The file on the hard disk
does not change. For other operations using the COPY command see the MS-DOS
documentation.
If you issue a command without specifying a drive, MS-DOS uses the current drive.

Accessing Executable Files on Disks

Usually executable files, or commands, are located on disks. There are three ways to access
an executable file.
1. Switch to the directory containing the file, type the file name and press Enter. To switch
to a directory, type the disk drive and colon, then cd, backslash and the directory’s
name. For example, to change from A drive to the DOS directory on drive C, type:
c: and press Enter, then
cd\dos and press Enter
Then type the name of the executable file.
2. The above process can be done in one step by including the full path name to the
executable file. For example, type:
c:\dos\TSETUP and press Enter.
3. Include the file’s path name in the PATH command you are currently using. Refer to your
MS-DOS documentation for information on the PATH command.
