如何获取插入计算机的可移动驱动器列表? [英] How can I get a list of removable drives plugged in the computer?

问题描述

我想获取插入计算机的可移动驱动程序列表.

我认为可以通过使用一些注册表来完成，但我不知道具体如何.

如果有其他方式我想听听.

注意:重要的是我将能够将可移动驱动器与固定驱动器分开.

解决方案

算法很简单:

• 调用 [MS.Docs]:GetGetLogicalDriveStringsW 函数，它将返回一个包含所有现有rootdirs(例如C:\\)的字符串，由NULL(em>\x00) 字符s
  • 迭代 rootdirs 并使用 [MS.Docs]:GetDriveTypeW 函数
  • 过滤可移动驱动器(类型为 DRIVE_REMOVABLE)

这就是它在 Python 中的样子(使用 PyWin32 包装器).将任何 win32con.DRIVE_* 常量添加到 drive_types 元组以获得不同的驱动器类型组合:

code00.py:

#!/usr/bin/env python3导入系统导入 win32con从 win32api 导入 GetLogicalDriveStrings从 win32file 导入 GetDriveTypedef get_drives_list(drive_types=(win32con.DRIVE_REMOVABLE,)):drive_str = GetLogicalDriveStrings()驱动器 = [drives_str.split("\x00") 中的项目的项目如果项目]如果 drive_types 为 None 或 Drive_types 中的 GetDriveType(item)，则为驱动器中的项目返回 [item[:2]]定义主():drive_filters_examples = [(无，全部")，((win32con.DRIVE_REMOVABLE,), "可移动"),((win32con.DRIVE_FIXED, win32con.DRIVE_CDROM), "Fixed and CDROM"),]for (drive_types_tuple, display_text) in drive_filters_examples:驱动器 = get_drives_list(drive_types=drive_types_tuple)打印({0:s} 个驱动器:".format(display_text))对于驱动器驱动器:打印({0:s}".格式(驱动器)，结束=")打印(\n")如果 __name__ == "__main__":print("Python {0:s} {1:d}bit on {2:s}\n".format(" ".join(item.strip() for item in sys.version.split("\n")), 64 如果 sys.maxsize > 0x100000000 否则 32, sys.platform))主要的()打印(\n完成.")

输出:

I would like to get a list of the removable drivers that are plugged in to the computer.

I think it can be done by using some registry, but I don't know how exactly.

If there is another way I would like to hear about it.

Note: It's important that I will be able to separate the removable drives from the fixed drives.

解决方案

The algorithm is straightforward:

• Call [MS.Docs]: GetGetLogicalDriveStringsW function, which will return a string containing all the existing rootdirs (e.g. C:\\) separated by NULL (\x00) chars
  • Iterate over the rootdirs and get each one's type using [MS.Docs]: GetDriveTypeW function
  • Filter the removable drives (having the type DRIVE_REMOVABLE)

This is how it looks in Python (using PyWin32 wrappers). Add any of win32con.DRIVE_* constants to drive_types tuple to get different drive types combinations:

code00.py:

#!/usr/bin/env python3

import sys
import win32con
from win32api import GetLogicalDriveStrings
from win32file import GetDriveType


def get_drives_list(drive_types=(win32con.DRIVE_REMOVABLE,)):
    drives_str = GetLogicalDriveStrings()
    drives = [item for item in drives_str.split("\x00") if item]
    return [item[:2] for item in drives if drive_types is None or GetDriveType(item) in drive_types]


def main():
    drive_filters_examples = [
        (None, "All"),
        ((win32con.DRIVE_REMOVABLE,), "Removable"),
        ((win32con.DRIVE_FIXED, win32con.DRIVE_CDROM), "Fixed and CDROM"),
    ]
    for (drive_types_tuple, display_text) in drive_filters_examples:
        drives = get_drives_list(drive_types=drive_types_tuple)
        print("{0:s} drives:".format(display_text))
        for drive in drives:
            print("{0:s}  ".format(drive), end="")
        print("\n")


if __name__ == "__main__":
    print("Python {0:s} {1:d}bit on {2:s}\n".format(" ".join(item.strip() for item in sys.version.split("\n")), 64 if sys.maxsize > 0x100000000 else 32, sys.platform))
    main()
    print("\nDone.")

Output:
