File does not open due to button/file deleted and put into the Recycle Bin.
Cause:
The toolbar button was deleted and this also will delete the file associated with the button. By default, files deleted from within Windows 95 are saved in the Recycle Bin until they are purged by the user.
Solution:
Select 'Restore' from the 'File' menu to restore the file. The file will be restored to the directory from which it was deleted.
