Error 201: Shapefile length

[Stolfus]

I have been trying to convert a few shapefiles to CAD and I get an error that says,
"The actual file length of this shapefile does not match the file length given in its header. This would indicate that the file is corrupt. Continue anyway?"
Does anyone know how to change the shapefile length, or how to get around this problem so that it will create my CAD file? I've clicked "yes" to continue and it doesn't work.
Thanks!

Hi Stolfus,

The message indicates that the shapefile is corrupt. The only reliable way to get around the problem is to contact the shapefile supplier and ask for uncorrupted data.

The file-length stored in the shapefile header is not stored arbitrarily, it is part of the shapefile specification. If the value does not match the actual length of the file then it simply means that the shapefile is invalid or corrupted.

Although the software gives the option to continue anyway and may actually be able read some data, it should not be relied upon to be complete or valid data.

Best of luck,
