在Windows 10的Ubuntu应用中获取父系统文件读写权限的方法

Hey there! Let's tackle this permission issue you're facing when accessing Windows files from your Microsoft Store-installed Ubuntu (WSL). The root cause lies in how WSL maps Windows file system permissions to Linux-style permissions, but we've got two reliable fixes to sort this out:

方法1：修改WSL的全局挂载权限配置（推荐） #

This is the cleanest way to set consistent permissions for all Windows files accessed via WSL, instead of adjusting each file individually.

• First, open your Ubuntu terminal and create/edit the WSL config file:

  sudo nano /etc/wsl.conf
  

• Paste the following content into the file. The umask value controls default permissions—0022 gives you read/write/execute access, while others get read/execute (a safe, standard setup):

  [automount]
  enabled = true
  options = "metadata,umask=0022,fmask=0133"
  mountFsTab = false
  

  If you need full read/write/execute access for everyone (not recommended for security, but useful in some cases), replace umask=0022,fmask=0133 with umask=0000.
• Save the file (press Ctrl+O, then Enter, then Ctrl+X to exit nano).
• Restart WSL to apply the changes: Open a Windows Command Prompt or PowerShell and run:

  wsl --shutdown
  

  Now reopen your Ubuntu terminal—your Windows files under /mnt/c (or other drives) should have the correct permissions.

方法2：在Windows中调整特定文件/文件夹的权限 #

If you only need to fix permissions for a single file or folder, you can adjust Windows' native security settings:

• Locate the target file/folder in Windows File Explorer, right-click it, and select Properties.
• Go to the Security tab, then click Edit to modify permissions.
• Click Add, type Authenticated Users into the text box, then click Check Names (it should auto-complete the full name). Click OK.
• In the permissions list for Authenticated Users, check the boxes for:
  • Read & Execute
  • List Folder Contents
  • Read
    If you need to modify the file/folder from Ubuntu, also check Write.
• For folders, check the box at the bottom that says Replace all child object permission entries with inheritable permission entries from this object to apply the settings to all subfiles/folders.
• Click Apply then OK to save changes. Go back to Ubuntu and try accessing the file again—it should work now.

A quick note: Avoid setting permissions for the Everyone group unless absolutely necessary, as it's a security risk. The sudo chmod command you tried only modifies the WSL permission layer, not the actual Windows security settings, so it won't stick long-term or fix the root issue.
