The filenames are not returned in any particular order. =so it is not possible to retrieve the filenames in alpha sequence. =Instead of taking the filenames directly from the readdir() and dropping them into the <option>, it may be necessary to put them first into an array/list. At the end of the while loop, the array could be sorted, and then another (for) loop implemented to copy the sorted list from the sorted array/list into the <option>s. =Regards, =dn
