Filename has multiple 3-character extensions due to custom extension saved.
Cause:
The file was saved with a user-created extension. Office 95 automatically adds the appropriate file format extension to the end of the file. This may result in files that look like: Filename.abc.txt.
Solution:
Select 'Save As' and select the file type. Then type the filename and extension enclosed in quotation marks.
1) Select the 'File' menu and select 'Save As...'.
2) Select the file type from the 'Save As Type' drop-down list.
3) Type the filename in quotation marks in the 'File Name' box.
EXAMPLE: ''Project.rmg''
4) Click 'Save'.
