Best way to check if there is a certain type of file in a folder? Maybe if fileexists with a wild card?

5 posts in this topic

Right now I am using the following code, but I feel like filefindfirstfile is a sloppy way to do this, in case the first file is not a zip file or an xml file, and neither is the second or third.

I could use if _filelisttoarray with a wild card I think but again that seems a little sloppy, but maybe there is a way to use if fileexists with a wild card?

if FileFindFirstFile(guictrlread($downloadbaklocation_box) & "\*.zip") = 1 Then
            RunWait(@WindowsDir & '\temp\7zip\7za.exe x ' & guictrlread($downloadbaklocation_box) & '\*.zip *.xml -oc:\temp\testxmls')
        Else
        $didnotfindzipfiles = 1
        MsgBox(0, "Error", "There are no .zip files in that folder")
        EndIf

if FileFindFirstFile(guictrlread($downloadbaklocation_box) & "\*.xml") = 1 Then
            _countdocsinnotif
        Else
        $didnotfindxmlfiles = 1
        MsgBox(0, "Error", "There are no .xml files in that folder")
        EndIf

Thanks for reading.

FileFindFirstFile() does not just check the first file in the directory. It returns a search handle when it finds the first MATCHING file. If it doesn't find one, it returns -1. So this is a test for *zip files:

$hSearch = FileFindFirstFile("C:\Temp\*.zip")
If $hSearch = -1 Then
     ConsoleWrite("No zip files." & @LF)
Else
     $sName = FileFindNextFile($hSearch)
     ConsoleWrite("First zip file: " & $sName & @LF)
EndIf
FileClose($hSearch)

Did you even try doing it yourself first? It didn't take me many hours minutes seconds to write this two-liner to test if FileExist supports wild cards:

$iTest = FileExists("F:\*.mp3")
ConsoleWrite(@error & "/" & VarGetType($iTest) & "/" & $iTest & @CRLF)

(and it works!)

Yes, I tried this, I'll have to look at my code and figure out why it failed
