Question

我在powershell中有一个脚本执行所有文件的计数，不久之后创建一个子文件夹就会停止每100个文件，这是肯定的，但是当我有例如：350个文件时，创建了3个文件夹，包含100个文件，其他50个被遗漏，有人可以帮助我，脚本如下：

$path = "c:\FILES";
$filecount = (Get-ChildItem $path).Count
$maxfilecount = 100;
#endregion variables

#region functions

# Define Write-DateTime function to alias
function Write-DateTime {
    return (Get-Date).ToString("yyyyMMdd hh:mm:ss");
}

# Set alias for quick reference
Set-Alias -Name wdt -Value "Write-DateTime";

#endregion functions

#region Script Body

# Output status to host.
Write-Output "$(wdt): Gathering file names.";

# Get file count
$filecount = (Get-ChildItem $path | Where-Object {$_.PSIsContainer -ne $true}).Count;

# Output status to host.
Write-Output "$(wdt): Processing files.";

# Enumerate folders based on filecount and maxfilecount parameter
for($i = 1; $i -le ($filecount/$maxfilecount); $i++) {

    # Clear the $files objects.
    $files = $null;

    # Set the foldername to zero-filled by joining the $path and counter ($i)
    $foldername = Join-Path -Path ($path) -ChildPath ("Disc-{0:0}" -f $i);

    # Output status to host.
    Write-Output "$(wdt): Creating folder $foldername.";

    # Create new folder based on loop counter
    New-Item -Path $foldername -ItemType Directory | Out-Null;

    # Output status to host. 
    Write-Output "$(wdt): Gathering files for $foldername.";

    # Break files into smaller collections to move to subfolders.
    $files = Get-ChildItem $path | Where-Object {$_.PSIsContainer -ne $true} | select -first $maxfilecount;

    # Output status to host.
    Write-Output "$(wdt): Moving files to $foldername.";

    # Enumerate collection.
    foreach($file in $files) {
        # Output status to host.
        Write-Output "$(wdt): Moving $($file.fullname).";

        # Move files in collection to subfolder.
        Move-Item -Path $file.fullname -Destination $foldername;
    }
}

这里for循环条件让你太短了：

for($i = 1; $i -le ($filecount/$maxfilecount); $i++) {

例如4 -le 350/100返回False，因此您只能获得三个文件夹。您可以将$i初始化为0，但这会影响文件夹名称，因此简单地将结束条件增加一个：

for($i = 1; $i -le ($filecount/$maxfilecount + 1); $i++) {

用于根据文件数将文件分割为子文件夹的脚本
