Windows Err Msg: File Manager Cannot Label the Disk

ID: Q93383

The information in this article applies to:

Microsoft Windows versions 3.1, 3.11
Microsoft Windows for Workgroups versions 3.1, 3.11

SUMMARY

Using File Manager to create a disk label containing a space character generates the following error message:


   File Manager cannot label the disk.

   Make sure the disk is not write-protected, is not a network
   drive, and that the label is valid.

   Labels cannot contain the following characters:
   [space] * ? / \ | . , ; : + = [ ] ( ) & ^ < > "

The error message is correct, but confusing because all versions of MS-DOS allow space characters in a disk label.

MORE INFORMATION

Page 517 of the "Microsoft MS-DOS User's Guide and Reference" manual for MS-DOS version 5.0 includes the following misleading statement:

A volume label can contain as many as 11 characters and can include spaces but no tabs. Consecutive spaces may be interpreted as a single space.

Using the MS-DOS label command to create a label of "A B C D E F" will return a label of "A B C D.E F". Because the first eight characters of an MS-DOS filename cannot end in a space, one or more spaces will be removed and a period inserted. For reasons such as this, it was decided to simplify the label parsing validation in File Manager to disallow space characters.
