Can't open Streets 2009 .est files using 2007/2008

[Veronica]

Our company has Streets 2007, 2008 and 2009. We have files on a SharePoint
site that were created using 2009. Some of the users who have older versions
of Streets cannot open these .est files. I can't find any information on
this issue. I am not a Streets user - just trying to help troublehshoot the
issue. If you have any information on this I sure would appreciate the help.
Thanks.

One of the "features" of Streets and Trips is that every new version
updates the file format. Every new version can read, but not write,
the old format. No version can read a format of a newer version. Any
time a new version reads an old file, it converts to the new format,
making the file no longer accessible to the old versions.

If you need to continue to support the older versions, I think your
only choice is to maintain multiple versions of your data files. :-(

Thank you for that clear and helpful infomation Rob. That's exactly what I
was looking for.

No they really don't have to maintain multiple versions, just maintain it
using the oldest version of S&T that's in use. Any changes that need to be
made to the files are also done using the oldest version of S&T in use.
Just don't allow the users to save over the shared copy that everyone
downloads.

Is there any way to convert 2009 maps so that older versions can read them.
