When you use File Manager to copy or move files less than 512 bytes in sizeto a write-protected floppy disk, the files are not copied to the floppydisk and no warning message is given. Also, when you move files less than512 bytes in size to a write-protected floppy disk, the files are notcopied to the destination drive but are deleted from the source drivewithout warning.
Microsoft has confirmed this to be a problem in File Manager in Windowsversions 3.1 and 3.11. We are researching this problem and will post newinformation here in the Microsoft Knowledge Base as it becomes available.This problem does not occur in Windows for Workgroups 3.1 or 3.11.
To work around this problem, remove write-protection from the floppy diskbefore moving or copying small files, or use an MS-DOS command prompt tocopy or move small files to a floppy disk.
When you copy or move files of 512 bytes or larger to a write-protectedfloppy disk, File Manager displays a warning message indicating that accessto the disk has been denied and suggests that the disk may be full or write-protected.
When you copy files smaller than 512 bytes to a write-protected floppydisk, File Manager displays a dialog box on the screen indicating that itis opening, copying, and closing the files. However, File Manager does notcopy the files to the write-protected disk.
Moving files smaller than 512 bytes to a write-protected floppy disk alsoresults in File Manager displaying a dialog box that indicates it isopening, copying, and closing the files; however, File Manager does notcopy the files to the write-protected disk, and, in fact, the files aredeleted from the source disk without warning.
NOTE: This problem occurs when copying or moving files from either a harddisk drive or a floppy disk drive to a write-protected floppy disk.
