Hi Jim & Rick,
Yeah, i'm running jBase under windows, due to the huge records stored
in the directory, the window explorer hanged somewhere once i open the
&COMO& file. Therefore, i'm trying to delete the files in jBase.
For the info you've provided, i manage to perform the task
successfully.
Thank you so much for your help. Appreciate everyone posted the
comment here.... :)
Good day and Best wishes,
Chloe
