We currently have many users with .nfsXXXX files inside their cur directory. What does that files mean?

They represent files that have been deleted, but are still being held open by some process. When the process closes the file, they _should_ disappear.

Unix semantics are that you can open a file, then unlink it, and still keep using the open file descriptor. When the file descriptor is closed, the storage is finally freed. This is convenient for temporary files (as well as being a sensible semantic for a multi-user system).

NFS, for reasons that escape me for the moment, doesn't work this way, so the .nfsNNNNN files are a work-around (rename instead of delete).
