Recursive Search / Filename

11 posts in this topic

I have searched the help file and the forums up and down but I just can not seem to find a solid answer.

I am looking for a function that will perform a recursive search for a file and retrieve the full file path including the file name.

I need to search for multiple files of the same extension so it would be best if it outputted the full file path and file name to an array.

Any help would be much appreciated.

Thanks.

Recursive Search

Actually, i wrote this code just now... you may have to edit it a little but in general it does what you want

Hi,

This is a recursive search script that I use. I found it on the forums a while ago, but I have no idea of the original author - so credit to who ever it was!.

Might need a bit of tweaking to fit your requirements, but I have found it very reliable.

; Search ("Base folder", "filename");replace as required

Func Search($current,$toFind)
    
If StringRight($current,1) <> "\" then $current &= "\"
    
Local $search_handle = FileFindFirstFile($current & "*.*")

While 1

    $file_found = FileFindNextFile($search_handle)
    
    If @error Or StringLen($file_found) < 1 Then ExitLoop
    
    If StringInStr(FileGetAttrib($current & $file_found), "D") And ($file_found <> "." Or $file_found <> "..") Then
        
; Search this subfolder
        Search($current & $file_found, $toFind) 
        
    Else
        
; Found file
    
    EndIf
WEnd

FileClose($search_handle)

EndFunc

Another example.

It appears to be working correctly.

#include <File.au3>
#include <Array.au3>

Global $sRet 
Local $sPath = @WindowsDir
Local $sFindFile = "calc.exe"

$aRetArray =  _FindPathName($sPath, $sFindFile)
_ArrayDisplay($aRetArray)


; Searches all subfolders of $sPath for $sFindFile (* and ? wildcards accepted)
; Returns an array containing full path and name of all matches.
; Number of matches is in zero index of array
Func _FindPathName($sPath, $sFindFile)
    Local $sSubFolderPath, $iIndex, $aFolders
    $search = FileFindFirstFile($sPath & "\" & $sFindFile)
    $aFolders = _FileListToArray($sPath, "*", 2)
    While 1
        $file = FileFindNextFile($search)
        If @error Then
            ExitLoop
        Else
            $sRet &= $sPath & "\" & $file & "|"
        EndIf
    WEnd
    FileClose($search)
    For $iIndex = 1 To $aFolders[0]
        $sSubFolderPath = $sPath & "\" & $aFolders[$iIndex]
        $aFoldersSubs = _FileListToArray($sSubFolderPath, "*", 2)
        If IsArray($aFoldersSubs) Then _FindPathName($sSubFolderPath, $sFindFile)
    Next
    Return StringSplit(StringTrimRight($sRet,1), "|")
EndFunc  ;==>_FindPathName

Wow...

Either you guys really like to post about recursive searches or this is the most helpful forum I have ever been to!

Thanks so much...

I don't know which one to use first! :)

Malkey,

I decided to go with your code being that it seemed to be the most strait forward to me... not that the others are bad though.

Anyway, I am very new to AutoIt and my only scripting experience in with Auto Hot Key (I actually thought AutoIt would be similar, but not so much)...

so would you mind explaining exactly what you did here? (especially the string functions which I have a hard time understanding)

I would appreciate it very much!

godsstigma,

FileFindFirstFile(),

FileFindNextFile(), and

FileClose() work together.

And,

_FileListToArray(),

StringSplit(), and

StringTrimRight are all in the help file.

When a matching file is found, the line

$sRet &= $sPath & "\" & $file & "|"

adds to the $sRet string, $sPath & "\" & $file & "|". This line using '&=' is a short-cut way of writing,

$sRet = $sRet & $sPath & "\" & $file & "|".

The "|" is there as a separator of the different matches found. It could be anything. As long as it is will not appear as a character in the found path/file name.

Because, on the Return line in the script, the string is split into an array using this character "|" as a delimiter.

StringSplit(StringTrimRight($sRet,1), "|")

But before the string is split, the last "|" of the $sRet string needs to be deleted. If not deleted, the StringSplit() will also split on the last "|" at the end of the string, $sRet, returning an array with a false blank array element at the end.

The StringTrimRight() function used, removes one character from the right of the string, $sRet, which is, and will be "|".

Hope this helps.

Malkey

Hi, I wrote this function for search files from a top folder specified as input value.

My main objective was to have a simple function that I can include in other codes, when I need to search or locate files in a tree.

I had located other codes, but those are ones that I need to embed my target operation INSIDE the search code.

Let me explain this:

Fucntion SearchFile (File_to find)
   (Begin  search engine)
    ; ----- Target Operation: 
          If file searched found, then do whatever you want
   (End of search Engine)
EndFunction

In other words, I need to modify the search function for every application that need search for a file.

My point is that I don´t want to touch a function that I had already tested and is working properly. I need a simple call to a function to search a file, do whatever I want with that file, and close the search whenever I need.

For example:

Function My_Taget_Function (My_Input Values)
   Some code
   (...)
  ; Then I need to search file(s) !!!
   $NotFound=True
   While $NotFound
      $File=ScanFolder(C:\Documents and Settings)
         If This is my file then
            Do whatever I want with the file
           ; And then stop search when done:
            ScanFolder (-ABORT-)
         EndIf
   Wend
   (...)
EndFunction

This is my code. I hope result useful for anyone. Greetings!

;----------------------------------------------------------------------------------------------------
;   Scan Folder Function
;
;   This Function scans files in the folder specified and sub folders tree (if any)
;   The first time it´s invoked CREATES a Search and returns the FULL PATH of the File found
;   Subsecuents calls, continues the search until no more files are found and closes de search
;   When end of search is reached, RETURNS -1 instead of the file name.
;
;   If the caller wants to cancel/stop/abort the search, calls the function with the Keyword "-ABORT-"
;   as Source Folder.
;
;   Input: 
;     Start Folder to Scan or "-ABORT-" 
;   Returns: 
;     Full path to file found or -1

Hello Saruman,

thanks for this source code, but I have a question. How can I modify this code to search one file (example : system.exe) in a patch c:\?

I want already have the properties of the file(s), size, version, date,... Could you help me?

Thanks in advance, Regards

Hello ricky03. First of all, sorry for the delayed reply, but I´m was off-line for some time.

I think that you do not need to modify the search code. In your main code you can filter the result what you want.

For example:

$File=""
$Version=""
$Size=""
$FileDate=""

While $File > -1
    $File = ScanFolder("C:\")
    If StringInstr($File, "system.exe") Then
        $Version=FileGetVersion($File, "FileVersion")
        $Size=FileGetSize ($File)
        $FileDate=FileGetTime ( $File,1,1)
    ; ETC.....
        FileWriteLine(@ScriptDir & "\ScanFolder.csv" ,$File & "," & $Version & "," & $Size & "," & $FileDate)
    EndIf

    ToolTip($File,0,200)
 
WEnd

I hope this can help you. Regards!
