PRJ4: "This Filename Is Not Valid" Even When Name IS Valid

 * }

Q114241

-

The information in this article applies to:


 * Microsoft Project for Windows, version 4.0

-

SYMPTOMS
In Microsoft Project 4.0, if there are no file handles available when you save a new project, or use the Save As command to save any project, the message

This filename is invalid is displayed

even if the filename is valid.

WORKAROUND
To work around this problem, save your new projects immediately after you create them.

STATUS
Microsoft has confirmed this to be a problem in the Microsoft products that are listed at the beginning of this article.

MORE INFORMATION
Windows has a maximum of 255 file handles, provided that the line Files=255 is in the CONFIG.SYS file (CONFIG.NT if you are using Windows NT). Windows has a minimum of about 128 file handles, regardless of the Files setting in the CONFIG.SYS file. This is an issue in Microsoft Project 4.0, because each OLE object created in an unsaved project is allocated one file handle, which is not released until the project is saved.

When you use the Paste Special command (on the Edit menu) to link text, you create an OLE link, not a DDE link. You may want to use DDE links because they do not require file handles.

For more information about creating DDE Links, query on the following words in the Microsoft Knowledge Base:
