如果您為工作設定了大量資料夾，並且在工作日需要在所有資料夾中使用相同的指令碼檔案，那麼除了大量複製和貼上之外，最簡單的方法是什麼？今天的超級使用者問答帖子為沮喪的讀者提供了一些有用的答案和建議。

問題

超級使用者閱讀器Elliot正在尋找讓同一個檔案同時出現在多個資料夾中的最佳方法：

I have 50+ folders, each of which contains a large amount of data that needs to be processed. All of them are processed using the same exact code, utilizing os.path.dirname(os.path.realpath(file)) to get the directory in which the python script is located so there is no manual editing needed by the user, they just need to double click.

I need the script to appear as if it is in each folder while actually being in only one place so that I can edit it once, then when it is run from any of these locati*** have the folder path be correct. The alternative is editing the master and then pasting it one folder at a time through all 50+ folders every time I update the code, which is very tedious and error prone. On Linux, I could set this up with a symbolic link, but I cannot figure out a way to do this with Windows.

Alternatively, a way to paste the file into all the target directories at once, instead of one at a time, would accomplish the same goal.

有沒有辦法做到這一點，而不是複製和貼上指令碼檔案一次一個資料夾？

答案

超級使用者貢獻者gronostaj為我們提供了以下答案：

You need a Symbolic Link or a Hard Link.

Symbolic Links (or Symlinks for short) are quite similar to shortcuts: there is one actual file and multiple references (Symlinks) to it. They even have that little arrow on the ic***. Unlike shortcuts, Symlinks can have any extension.

Hard Links bind a file on a hard drive to a location in the directory tree. Each file has at least one Hard Link, otherwise it would not exist in any directory. If a file has multiple Hard Links, the original one cannot be distinguished from the others and the file physically exists in only one location.

Both Have Their Limitati***:

• Some software does not play nicely with Symlinks.
• Deleting the original file leaves all of its Symlinks broken.
• You cannot Hard Link folders (but you can create a Directory Junction if a Symlink is not enough).
• Creating cross-partition Hard Links is impossible.

Symlinks are usually sufficient.

To Create a Symlink or a Hard Link:

1. Launch a privileged command line: Press the Windows Key, type cmd, then press Ctrl+Shift+Enter.

2. Issue the mklink command:

• mklink link_name link_target for a file Symlink
• mklink /d link_name link_target for a folder Symlink
• mklink /h link_name link_target for a file Hard Link
• mklink /j link_name link_target for a Directory Junction
