Passing a path ending with a backslash to a native command appends trailing quote #28130
Description
Activity
Please note that this repo is exclusively for Powershell (Core) 7 (
pwsh.exe/pwsh), and not also for Windows PowerShell (powershell.exe, the legacy, ships-with-Windows, Windows-only closed-source edition of PowerShell located inC:\Windows\System32\WindowsPowerShellwhose latest and final version is 5.1)What you're seeing ia a well-known bug in Window PowerShell that has since been fixed in PowerShell (Core) 7.3+
Given that Windows PowerShell will see security-critical fixes only, it is highly unlikely that the problem will be fixed there.
One workaround: double the\at the end of the string:.\test.exe 'C:\Test Draw\3D\3D\50obj\\'For background information, see this Stack Overflow answer.

Description
When a Windows native C++ program is invoked from PowerShell with a single-quoted path ending in a backslash, an unexpected double quote (
") is appended to the argument.For example:
The C++ program prints the following:
The expected value of
argv[1]is:but the actual value contains an unexpected trailing double quote:
This causes filesystem operations using the argument to fail. For example:
returns
falsebecause the resulting path is invalid.Expected behavior
The trailing backslash should be preserved as part of the argument, without adding an extra double quote:
Expected behavior
C:\Test Draw\3D\3D\50obj\Actual behavior
C:\Test Draw\3D\3D\50obj"Error details
