Copy and Move Messages

Following are several specific MS-DOS Shell messages you may receive when moving and copying files and advice about how to handle them.

Invalid Path
------------
Make sure that you specified the correct path for the file or directory (including the correct drive letter). The path is the location of the file or directory in the directory tree. The entire path must not be longer than 66 characters. For more information about paths, see "MS-DOS Basics," in the User's Guide.

File or Drive Does Not Exist
----------------------------
Check to be sure the drive, path, and filename are correct. Use the file list to make sure the file is on the disk in the specified drive. Try using the Refresh command on the View menu to update the file list.

You Have More than One File Selected
------------------------------------
When you have more than one file selected that you want to copy or move, you must specify a destination directory -- not a file. Make sure you specified an existing directory and that its path is correct.

Access Denied
-------------
You may have tried using a file that you do not have access rights to. Check with your system administrator.@@

File List Messages

Following are several specific MS-DOS Shell messages you may receive and advice about how to handle them.

The File Doesn't Exist
----------------------
Make sure you specified the correct path and filename.

Access Denied or Invalid Path
-----------------------------
You may have tried one of the following:

   * Specifying an incorrect path. Make sure that you    
     specified the correct path for the file or directory
     (including the correct drive letter). The path is the
     location of the file or directory in the directory
     tree.

   * Renaming a file or directory to one that already exists
     in the same directory.

   * Within a directory, creating a new directory with the
     same name as a directory that already exists.

   * Deleting a directory that contains files. First you
     must delete or move the files.

   * Deleting a write-protected or read-only file. Try
     changing the file's attributes by using the Change
     Attributes command on the File menu.

   * Trying to perform operations on a write-protected disk.
     Remove the write-protection from the disk.

   * Using a file that you do not have access rights to.
     Check with your system administrator.

   * Creating a directory with a path that's too long.
     MS-DOS recognizes paths up to 66 characters (including
     the drive and colon [:]). Try specifying a shorter path
     for the directory.

For more information about paths, see "MS-DOS Basics" in the User's Guide.

That is the Wrong Floppy Disk
-----------------------------
Be sure you inserted the correct disk in the drive. When you insert the correct disk, MS-DOS Shell will continue with the operation.

That Drive Doesn't Exist
------------------------
Make sure you specified the correct drive letter. If you are using a network, make sure you are connected to it. Try using the Refresh command on the View menu to reread the drives.

Drive Not Ready
---------------
Check the drive to be sure of the following:

  * A disk is in the drive.

  * The drive door is closed.

  * The disk is properly inserted in the drive.

  * The disk is formatted.

Unrecognized Disk Error
-----------------------
If you're using a floppy disk, check to be sure that you've inserted the correct disk in the drive, that it is inserted properly, and that the drive door is closed.

Check to see that the disk and the drive are compatible. For example, you may be putting a high-density disk into a drive that only accepts low-density disks.

The disk may contain bad sectors. You can use the CHKDSK command at the command prompt to see if there are bad sectors on the disk.

Error Reading File
------------------
Make sure the file exists on the specified drive.

Error Writing to the Destination File
-------------------------------------
Make sure you inserted the correct disk in the drive. Or, it could be that the disk is damaged.

The File is in Use by Someone Else
----------------------------------
You tried to use a file on a network that someone else is using. To use the file, you must wait until it is available.

Take the Write-Protection off the Disk
---------------------------------------
The disk you are trying to use may have write-protection. This prevents data from being written to the disk. Remove the write-protection, or use a different disk without write-protection.

Error creating a temporary file on a drive
------------------------------------------
MS-DOS Shell cannot find the TEMP or TMP variable and you have tried to start a program from a write-protected disk. Temporary files cannot be created. You can either remove the write-protection from the disk, or set the TEMP or TMP variable in the AUTOEXEC.BAT file.

For more information about setting these variables, see
   "Setting the TEMP or TMP Variable"~I167~

Unrecognized Error
------------------
Retry the operation. If you still get a message, quit MS-DOS Shell and start it again, and then retry the procedure.

!I167!@
Setting the TEMP or TMP Variable

In the process of starting and quitting programs and MS-DOS Shell, temporary batch files are created and stored in a directory specified in the TEMP or TMP variables in your AUTOEXEC.BAT file.

You may have to reset the TEMP or TMP variable if:

  * The disk you want to restore deleted files from is full.
    The temporary files may overwrite deleted files you want
    to restore.

  * You started MS-DOS Shell from a write-protected disk.
    You will not be able to start the program.

When you start a program, MS-DOS Shell first looks for the directory specified in the TEMP variable and then in the TMP variable. If it can't find the directories, MS-DOS Shell will use the directory and drive where the running MS-DOS Shell is stored. If MS-DOS Shell can't create the temporary batch file in any of these directories, it displays the message "Error creating a temporary file to a drive."

The problem may be that you are running MS-DOS Shell from a write-protected disk.

You can try the following:

  * Remove the write-protection from the disks.

  * Set the TEMP or TMP variable to a directory on a
    disk that isn't write-protected.

NOTE: It's best to set the variable to a directory on the RAM drive. If the RAM drive doesn't have enough memory, specify a different directory.


To set the TEMP and TMP variables:

1. Quit MS-DOS Shell.

2. Choose or create a directory for the temporary files -- 
   for example, c:\temp; or if d: is your RAM drive, you
   could specify d:\. 

3. At the MS-DOS command prompt, use the set command to set
   each variable.

   To set this variable    Type
   --------------------    ----
   TEMP                    set TEMP=drive:\directory
   TMP                     set TMP=drive:\directory

   Specify the directory that you chose or created in Step
   2.

   NOTE: The TEMP and TMP variable can specify the same 
   or a different directory.

   NOTE: It's recommended that you set both variables 
   now so that no matter which program you will be using,
   the variable it uses will be set correctly.

4. Press ENTER.

5. Start MS-DOS Shell.@@
