我遇到了一个奇怪的问题，我想知道是什么原因造成的。我有一个文件，它肯定存在：
Get-ChildItem -Path '\\192.168.10.201\Media\TV\Life With an Ordinary Guy Who Reincarnated Into a Total Fantasy Knockout\Life.With.an.Ordinary.Guy.Who.Reincarnated.Into.a.Total.Fantasy.Knockout.S01E03.An.Ordinary.Guy.Who.Reincarnated.Into.A.Total.Fantasy.Knockout.And.An.Angry.Elf.mkv'

但是当我尝试将它传递给ffprobe它时出现错误：

我也尝试将它传递给，notepad并且正如预期的那样，它花了一段时间才能打开，然后出现为垃圾。
我可以毫无意外地打开同一目录中的其他文件，因此这并不是ffprobe访问 SMB 共享时遇到的任何问题：

我可以轻松重命名此文件以避免该问题，但我想知道这可能会影响哪些其他文件。
我将其标记为 PowerShell （因为我在那里测试它）但如果我使用 NodeJS 启动 ffprobe ，我也会看到同样的问题child_process。
答案1
经过仔细检查，它似乎ffprobe支持最大路径长度为 259 个字符。
我认为，由于 Windows 长期以来一直支持较长的路径，因此不再需要担心这个问题。但我猜软件必须更新才能支持长路径。
