Hi Koen,
Did you try CLOSE INDEXES? From the help:
CLOSE INDEXES
Closes all open index files (both single-entry .idx and independent compound .cdx files) in the current work area. A structural compound index (a .cdx file automatically opened with the table) is not closed.
Also ATAGINFO can help you, but I am not sure if it will distinguish non-structural CDX files (Update: Well, I guess you can check the name as the structural CDX will have the same name/path of the table, right?)
