Vicent,

Is not a permission problem.

The rebuild will create the k files on the first folder from datapath. You can get this same problem with a workspace with 2 folders in datapath .\Path1;.Path2\. If you delete the k files form Path2 and to reindex, the k files will be created ont Path1.

With CM, the files was created on the CM installation folder.

To solve the problem, I copied all K files from another site and did a reinidex.

I think that is necessary to change the DataPath on Reindex CM process to avoid this problem.

Ivan Kaupa
