Python os.path.isfile抱怨映射的网络驱动器中的文件不存在

标签： python network-drive

在本地网络中共享的文件夹被映射到Windows 10中的网络驱动器（字母V:）。以下python行检查文件是否在映射的网络驱动器中：

import os
print(os.path.isfile("V:\\FORENSOR DTB Dataset processed\\pow_day_125236_07.5.avi"))

这将返回false。文件夹中的任何文件都会发生相同的情况。 copyfile()中的shutils还会引发错误，指出文件不存在。但是该文件在文件夹中。这是什么问题？

在建议/链接的答案之后，我尝试了以下所有操作（V:是驱动器号，DARAS-NAS是网络位置的名称）：

print(os.path.isfile(r'\\DARAS-NAS\FORENSOR DTB Dataset processed\pow_day_125236_07.5.avi'))
print(os.path.isfile(r'\\DARAS-NAS\\FORENSOR DTB Dataset processed\\pow_day_125236_07.5.avi'))
print(os.path.isfile(r'\\\\DARAS-NAS\FORENSOR DTB Dataset processed\pow_day_125236_07.5.avi'))
print(os.path.isfile(r'\\\\DARAS-NAS\\FORENSOR DTB Dataset processed\\pow_day_125236_07.5.avi'))

也许是这项工作：

public interface IWatch
{
     void Watch();

                                                                  new RemoteCsvFilesRepository(new DbManager(ConnectionDbType.MySql)),

        var coll1 = new CollectionService(fileWatcherServiceCsv);
        }
}

public interface IEntity

}


public interface IFileEntity : IEntity

    int Id { get; set; }

    public string MainNode { get; set; }
}

只需调用它，文件将是文件的路径，文件名为它自己。
