Need to get count of files in a folder

[OldMike]

Need to simply count the number of files in a folder. Found postings re: FileListToArray, but it is not listed in the on line documentation of functions.

You should have been able to find it in the online help ... but here it is: quoting from the AutoIT help file.

_FileListToArray

--------------------------------------------------------------------------------

Lists files and\or folders in a specified path (Similar to using Dir with the /B Switch)

#Include <File.au3>

_FileListToArray($sPath [, $sFilter = "*" [, $iFlag = 0]])

Parameters

$sPath Path to generate filelist for.

$sFilter [optional] the filter to use, default is *. Search the Autoit3 helpfile for the word "WildCards" For details.

$iFlag [optional] specifies whether to return files folders or both

$iFlag=0(Default) Return both files and folders

$iFlag=1 Return files only

$iFlag=2 Return Folders only

Return Value

Success: an Array, see remarks

Failure: 0

@Error: 1 = Path not found or invalid

2 = Invalid $sFilter

3 = Invalid $iFlag

4 = No File(s) Found

Remarks

The array returned is one-dimensional and is made up as follows:

$array[0] = Number of Files\Folders returned

$array[1] = 1st File\Folder

$array[2] = 2nd File\Folder

$array[3] = 3rd File\Folder

$array[n] = nth File\Folder

Example

#Include <File.au3>

#Include <Array.au3>

$FileList=_FileListToArray(@DesktopDir)

If @Error=1 Then

MsgBox (0,"","No Folders Found.")

Exit

EndIf

If @Error=4 Then

MsgBox (0,"","No Files Found.")

Exit

EndIf

_ArrayDisplay($FileList,"$FileList")

Try searching the help file for "_FileListToArray" (note leading "_")

HTH,

Thanks; just what I need.

So, there are functions documented in the editor Help that are not listed in the on line documentation list of functions???? Seems simple to copy one into the other.

I have a hunch the OP did not take a look at the "User Defined Functions" part of the help file. Those functions are not native to AutoIt and _FileListToArray() is one of them under "File Management"

EDIT: I'm not sure if it is actually included in the official On-line docs for AutoIt but it is in my on-line docs and that link is in my signature although I should probaly modify my signature to show it is not the normal AutoIt On-line.

I have four files to check, all are in D:, named P1, P2, P3, P4. I need to check the number of PDF files in each. It seems this should work, runs without errors, but returns null.

#include<file.au3>

#Include<array.au3>

Global $fcnt[1]

For $n = 1 to 4

$path = _Pathmake("D:","\P"&$n,"\*.pdf","")

$fcnt[0] = _FileListToArray($path)

MsgBox(0,"","Number of files in P" & $n & " is: "&$fcnt[0])

Next

First, you're not reading the files in the path, you're trying to read the files in a path name that contains the return result of your function _Pathmake, which is probably equivalent to _FileListToArray(0) where the 0 is the path the function is trying to read from. Second, use $fcnt = _FileListToArray($path) without the [0] element of the array. _FileListToArray returns an array of file names and puts them into your array, and the [0] element holds the number of files it finds, you just need to use the array name to have everything put into the array correctly.

[OldMike]

I removed [0] from the $fcnt = _FileListToArray($path), then got an error message on the line with msgbox unless I deleted it there too. The error message is "Subscript used on nonarray variable." When I do remove it on that line too, I am back to a null result.

I don't understand your comment about the path; could you suggest how that line should read? I am trying to read from:

D:\P1

D:\P2

D:\P3

D:\p4

Thanks for your patience.

OK, got it going now. Doesn't square with the documentation, but it works:

#include<file.au3>

#Include<array.au3>

Global $fcnt

For $n = 1 to 4

$path = "D:\P" & $n

$fcnt = _FileListToArray($path,"*.pdf",1)

MsgBox(0,"","Number of files in P" & $n & " is: "&$fcnt[0])

OldMike,

Doesn't square with the documentation

Yes it does - why do you think it does not?
