Detect Multiple Files in sub directories

Recommended Posts

Hello All,

I have found a FileListToArray function that will search a location and find a certain file extension then put it into an array, What I am trying to figure out is how to only list the ones with multpile files in the directory. In this case I am looking for *.ost files only. I want to see what folders have more than one OST file in them so that I can delete the oldest one.


Here is the array function

#include <Array.au3>

Global $a1, $b1

$b1 = _FileListToArrayEx("O:\", "*.ost", 12)
;_ArrayDisplay($b1,"OST Found")

global $maxa = Ubound($b1)

for $i = 0 to $maxa -1

; #FUNCTION# ========================================================================================================================
; Name...........: _FileListToArray
; Description ...: Lists files and\or folders in a specified path (Similar to using Dir with the /B Switch)
; Syntax.........: _FileListToArray($sPath[, $sFilter = "*"[, $iFlag = 0]])
; Parameters ....: $sPath   - Path to generate filelist for.
;                 $sFilter - Optional the filter to use, default is *. (Multiple filter groups such as "All "*.png|*.jpg|*.bmp") Search the Autoit3 helpfile for the word "WildCards" For details.
;                 $iFlag   - Optional: specifies whether to return files folders or both Or Full Path (add the flags together for multiple operations):
;                 |$iFlag = 0 (Default) Return both files and folders
;                 |$iFlag = 1 Return files only
;                 |$iFlag = 2 Return Folders only
;                 |$iFlag = 4 Search subdirectory
;                 |$iFlag = 8 Return Full Path
; Return values .: @Error - 1 = Path not found or invalid
;                 |2 = Invalid $sFilter
;                 |3 = Invalid $iFlag
;                 |4 = No File(s) Found
; Author ........: SolidSnake <MetalGX91 at GMail dot com>
; Modified.......:
; 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

    Return StringSplit(StringTrimLeft($sFileList, 1), "|")

Any help is appreciated.

      i have a script that selects  a text file and deletes a line (text input required) in the text file selected
      i have to make it remove all lines found on a file i name, toRemoveLines.txt
      it has to remove lines from all text files found in a folder
      this is the script that has to be modified
      where it says "select file" it has to be "select folder"
      where it says "line text input" it has to be all lines from a text file
      #Include <File.au3> Global $success = False $file_name = FileOpenDialog("Select file", @ScriptDir, "All files (*.*)", 1+4) $line_text_input = InputBox("Line's text", "Line must contain following text:", "line contains this text") $file_count_lines = _FileCountLines($file_name) for $i = 0 to $file_count_lines $Lines_text_output = FileReadLine($file_name, $i) if StringInStr($Lines_text_output, $line_text_input) then _FileWriteToLine($file_name, $i, "", 1) $success = True ExitLoop EndIf Next if $success = True Then MsgBox(0, "Success", "Line has been deleted") Else MsgBox(0, "Failure", "Line wasn't found") EndIf

      I have a query please
      It is about windows file explorer
      If i design a tool in autoit language to delete files for example
      and i  added it in the context menu in File Explorer
      If i right-click on any file And you choose the tool, it will be get the path of the selected file or folder
      The problem here is
      If i select a set of files or folders
      it only detect the first one
      The code that i  used is
      if $CMDLine[0] = 0 then
      msgBox(16, "error", "you don't selecte any files")
      for $i = 1 to $CMDLine[0]
      msgBox(0, "files", $CMDLine[$i]

      Files Checklist
      Just a simple little (complex enough) program I whipped up, for a purpose ... but only too happy to share.
      It can of course be modified to do more, but at the moment just compares file names with or without path ... Location versus Checklist.
      There are of course other compare programs out there, most doing a lot more than mine (i.e. WinMerge or FileComparer). But I wanted something quick and simple with drag & drop, that uses up a smallish amount of screen real estate.
      NOTE - The SAVE button is also a LOAD one, and displays 'Load' when the list is empty. So you can save and load specific lists. While in SAVE mode, the button can also be used with CTRL held down, to ADD another list to existing (displayed one) ... combining as they say ... though not saved until you SAVE. CLEAR button removes a selected entry, or if used with CTRL held down, queries about removing all listed entries.
      Files Checklist v1.2.zip
      Files Checklist v1.3.zip
      Files Checklist v1.4.zip  (Includes a BUGFIX.)
        (source included)
      WARNING - While this program does not act on files or folders ADDED or CHECKED, you might act on the results, so I advise caution, and I also recommend using the new 'Relative' option in v1.3 or newer ... but you still need to understand what you are doing and what the results actually mean. Some basic examples in the next post.
      Users might also be interested in another somewhat related program of mine.
