我被要求解决以下问题：在新创建的文件夹中分批复制 3 个文件。示例：在文件夹中假设“D:/TEST_CF/”有 20 个 txt 文件。将它们除以 3（批次给我们 6 余数 2），创建 7 个文件夹（以便将 3 的批次放在 6 个文件夹中，其余 2 个文件放在第 7 个文件夹中）。到目前为止，我所做的是创建所需的文件夹。但是，我无法将文件复制到新创建的文件夹中的 3 批中。我应该如何解决上述问题？

正如史蒂夫所说，您需要一个循环两个或更好的函数来执行 fileMove 操作。

笔记

  • 逻辑只是一个 POC。您可以将其改进为更好的。

  • 我在CF10上试过这个代码。它也必须在 Open DB 上正常工作。

    <cfprocessingdirective pageencoding="UTF-8">

<cfscript>
    oDirectoryPath      = "D:/test_cf/"; //original Directory path
    files               = DirectoryList(oDirectoryPath, false, 'name', '*.*');
    filecount           = Arraylen(files);
    filePerFolder       = 3;
    numfoldersToCreate  = Ceiling(filecount/filePerFolder);

    function moveFilesToThisDirectory(dir,index){
        var beginAt = 1;
        var endAt   = begin + 2;
        var newDir  = ARGUMENTS.dir;

        beginAt = ARGUMENTS.index;

        if(beginAt neq 1){
            endAt = index * VARIABLES.filePerFolder;
            beginAt = endAt - (VARIABLES.filePerFolder - 1);
            if(endAt GT VARIABLES.fileCount){
                endAt = VARIABLES.fileCount;
            }
        }

        while(beginAt LTE endAt){
            FileMove(oDirectoryPath & '\' & files[beginAt], newDir & '\' & files[beginAt]);
            beginAt = beginAt + 1;
        }

    }
</cfscript>

<cfif directoryExists(oDirectoryPath)>        
        <cfdirectory action="list" directory="#oDirectoryPath#" name="directories" recurse="true" type="dir" />
        <cfloop query="directories">
                <cfdirectory action="delete" directory="#oDirectoryPath#/#directories.name#" recurse="yes">
        </cfloop>
</cfif>

<cfscript>

    i = 1;
    while(i LTE numfoldersToCreate){
        newDirectoryName = "#oDirectoryPath#newfolder#i#";
        DirectoryCreate(newDirectoryName);
        moveFilesToThisDirectory(dir:newDirectoryName,index:i );
        i = i + 1;
    }

    switch(numfoldersToCreate){
        case 0:
            WriteOutput(' No folder created');
            break;
        case 1:
            WriteOutput(' 1 folder created');
            break;
        default:
            WriteOutput(numfoldersToCreate & ' folders created');
    }
</cfscript>
