Using FileDelete on a mapped network-drive

[XorpiZ 0]

Hi,

I've developed a small script that reads several lines from a textfile and then deletes any files matching those lines from a specific folder. It works splendidly on my local disk, but when I try running it on a mapped network-drive it's unable to delete any files.

If I run the script on ie. c:testfolder FileFindFirstFile will return a "handle" if a match is found. If I run the script on M:testfolder (M: is a mapped drive from our server) it will always return -1.

I have full rights to the folder.

Any ideas? I realize it's not 'comme il faut' to post a question as your first post on a forum.. but I'm really curious as to why it's not working :-) Also, the code below isn't beautiful.. :-)

BR,

Thomas

#include <File.au3>

$file = FileOpenDialog("Choose the file containing the list", "c:\", "Text files (*.txt)");
FileOpen($file, 0); Open the file
$folder = FileSelectFolder("Choose the folder containing the files", "")
Local $search = FileFindFirstFile($folder & "\*.*"); Make a list of files
MsgBox(0, "", $folder)
If $search = -1 Then
    MsgBox(0, "Error", "No files/directories matched the search pattern");If empty folder, show error
    Exit
EndIf

$counter = 0

For $i = 1 to _FileCountLines($file) ;Loop through the file
    $line = FileReadLine($file, $i) ;Get line $i
    $filesearch = FileFindFirstFile($line & "*");Search for $line + wildcard
    If $filesearch <> -1 Then;Check if match found
        FileDelete("*" & $line & "*");Delete any matching files
        $counter += 1
    Else
        ;MsgBox(0, "", "Mappe: " & $folder & " --- Filnavn: " & $line) DEBUG - Can be ignored
    EndIf
Next
If $counter == 0 Then
    MsgBox(0, "", "No files were found!");
    Else
        MsgBox(0, "", "Done! Deleted " & $counter & " unique files.")
EndIf
FileClose($file)

Just a follow up - If I manually write the filename - FileDelete($folder & "filename.txt") it works just fine, so it could perhaps be the FileFindFirstFile that's having issues searching on a mapped drive?

Welcome to AutoIt and the forum!

In the loop you should replace FileFindFirstFile with FileFindNextFile.

FileFindFirstFile creates a list of files and returns a handle, FileFindNextFile returns entry by entry of this list, FileFindClose releases the handle and the list.

Hi, and thanks! :-)

I just replaced it with "FileFindNextFile", and now I do get results that match my expectations. But FileDelete doesn't do anything now

If $filesearch <> -1 Then;Check if match found
    FileDelete("*" & $line & "*");Delete any matching files
    $counter += 1
Endif

use FileDelete with absolute path:

FileDelete($folder & "*" & $line & "*");Delete any matching files

You need to pass the handle not the filename:

#include <File.au3>

$file = FileOpenDialog("Choose the file containing the list", "c:\", "Text files (*.txt)");
FileOpen($file, 0); Open the file
$folder = FileSelectFolder("Choose the folder containing the files", "")
Local $search = FileFindFirstFile($folder & "\*.*"); Make a list of files
If $search = -1 Then
    MsgBox(0, "Error", "No files/directories matched the search pattern");If empty folder, show error
    Exit
EndIf

$counter = 0

For $i = 1 to _FileCountLines($file) ;Loop through the file
    $line = FileReadLine($file, $i) ;Get line $i
    $filesearch = FileFindNextFile($search)
    If $filesearch <> -1 Then;Check if match found
        FileDelete($filesearch);Delete any matching files
        $counter += 1
    Else
        ;MsgBox(0, "", "Mappe: " & $folder & " --- Filnavn: " & $line) DEBUG - Can be ignored
    EndIf
Next
If $counter == 0 Then
    MsgBox(0, "", "No files were found!");
    Else
        MsgBox(0, "", "Done! Deleted " & $counter & " unique files.")
EndIf
FileClose($search)
FileClose($file)

What I don't get is what you want to do.
Delete all files in the folder the user selects or delete the files you take from the text files?

water, does FileDelete (and FileCopy, FileMove & friends) support file handles? the help file does not mention that...

use FileDelete with absolute path:

FileDelete($folder & "*" & $line & "*");Delete any matching files

 

Thanks! That did the trick! :-)

I have a textfile containing anything from 1 to 300 hundred filenames, each on their own line.

I need the script to read each line from the textfile and then delete any file matching that filename in the folder that the user selects.

I couldn't get it to work by passing the handle to FileDelete, but giving it an absolute path worked. I'm a bit curious as to why it didn't need an absolute path when working with local files though, but I guess that's one of the big mysteries of life! :-)

You could then strip down your script a bit:

#include <File.au3>
Global $aFileToDelete, $iCounter = 0
$sFile = FileOpenDialog("Choose the file containing the list", "c:\", "Text files (*.txt)");
If $sFile = "" Or @error Then Exit
_FileReadToArray($sFile, $aFileToDelete)
If @error Then Exit MsgBox(16, "Error", "Error reading " & $sFile)
$sFolder = FileSelectFolder("Choose the folder containing the files", "")
If $sFolder = "" Or @error Then Exit
For $i = 1 To $aFileToDelete[0] ; Loop through the file
    If FileDelete($sFolder & "\" & $aFileToDelete[$i] & "*") <> 0 Then $iCounter += 1 ; Delete any matching files and increment counter if successful
Next
If $iCounter = 0 Then
    MsgBox(64, "Information", "No files were deleted!");
Else
    MsgBox(64, "Information", "Done! Deleted " & $iCounter & " unique files.")
EndIf
