Using SrchInit for 2 Filetypes

Keywords: 

Question:

What is the most efficient way to search an entire hard disk for two filetypes? I want to avoid two complete scans which is what I think is happening now. Currently I scan for one type, *.LNK, then for the other, *.PIF. Here is the main part of my code:
AddExtender("wsrch34I.dll")

;*** Scan HD for PIF & LNK Files
;*** Change UNC Names to P:
;*** Change "Smart" Icons to "Dumb"

drives = DiskScan(2)
drvnum = ItemCount(drives,@TAB)
chk = StrLower("\\nt000036\programs")
lgth_chk = StrLen(chk)
For d = 1 to drvnum
    drv = ItemExtract(d,drives,@TAB)
    drvroot = StrCat(drv,"\")
    For x = 1 to 2
        If x == 1 then search = "*.LNK"
        Else search = "*.PIF"
        handle1 = srchInit(drvroot,search,"%chk%","",16)
        While 1
            lnk = srchNext(handle1)
            if lnk == "" then Break
            Display(1,"Found",lnk)
        endwhile
    Next
Next

Answer:

Something like searching for *.* and then checking what you got. See below.
handle1 = srchInit(drvroot,"*.*",chk,"",16)

While 1
    lnk = srchNext(handle1)
    if lnk == "" then Break 
    ext=strlower(FileExtension(lnk))
    if ext!="pif" && ext!="lnk" then continue
    etc...

The problem here is that *each* and *every* file on the system is "touched" and is likely to take MUCH MUCH MUCH longer that two separate scans.
