This is similar to Jim's post, but you may find it a bit more robust when there are no files present. Also, I've added your actual path as well as a memo field to contain the path and filename regardless of how long the path might get.

CREATE TABLE textfiles (filename c(10),withpath m)
lnFileCnt = ADIR(laFileArray,'f:\convert\*.txt')
IF lnFileCnt > 0
FOR lnFile = 1 TO lnFileCnt
APPEND BLANK
REPLACE filename WITH laFileArray(lnFile,1)
REPLACE withpath WITH FULLPATH(laFileArray(lnFile,1))
ENDFOR
ELSE
WAIT WINDOW "No Files Found" NOWAIT
