You could remove the DBF's backlink to the DBC, then recreate the indexes, then restore the backlink. I think Primary/candidate is stored in the DBC, not the CDX, so that setting won't be lost (though I'm not sure).

Restoring the backlink is similar...

*FUNCTION RemCDX( pcFile )
LPARAMETERS pcFile
LOCAL   lnHandle, laJnk[1], lcFlags, oErr, lnRes, lcType, lnHdrLen, lcHdrLen
PRIVATE nErr
nErr  = 0
lnRes = 0
if adir(laJnk,pcFile)=0
  RETURN -1
endif
lnFileSize = laJnk[2]
lnHandle = THIS.LLFF.FOPEN(pcFile,12)   && Open file, R/W, Unbuffered
IF lnHandle <= 0
  RETURN iif(lnHandle=0,-1,lnHandle)
ENDIF

oErr = On("ERROR")
ON ERROR nErr=Error()

lcType = THIS.LLFF.FREAD(1)
if ASC(lcType)<>0x30 && Visual Foxpro
  THIS.LLFF.FCLOSE
  ON ERROR &oErr
  RETURN 0
endif

* Find start of DBC name
THIS.LLFF.FSEEK(8,0) && First Record Pointer
lcHdrLen = THIS.LLFF.FREAD(2)
lnHdrLen = ASC(lcHdrLen) + ASC(SubStr(lcHdrLen,2))*256
  
* Clear out DBC name
THIS.LLFF.FSEEK(lnHdrLen-263,0)
THIS.LLFF.FWRITE( REPL(chr(0),263) )
  
THIS.LLFF.FCLOSE
ON ERROR &oErr

RETURN lnRes
