Fail to copy for filename containing square brackets '[ ]'

[cho-uc]

Copying files with filename containing squarebracket "[ ]" will fail

Example:

• Myfilename[123].txt -> fail, file is corrupted, but no error message
• Myfailname].txt -> success
• Myfailname[.txt -> fail with attached error message

Windows version : Windows 10 Version 22H2
PSVersion : 5.1.19041.5007

Command:
Copy-FileHash -Path .\Source\ -Destination .\Destination\ -Recurse -PassThru -Verbose

This is because the -Path parameter interprets square brackets as special characters. Other PowerShell cmdlets that handle paths do the same.

To have the square brackets treated literally, use the -LiteralPath parameter instead of -Path.

Hello,

Thank you for the quick reply.
I replaced the command with -LiteralPath but the issue persisted.
Copy-FileHash -LiteralPath .\Source\ -Destination .\Destination\ -Recurse -PassThru -Verbose

The file Myfilename[123].txt is inside Source folder.
Is the command above correct?

I see the problem. The -LiteralPath parameter only applies to the source path, it doesn't use LiteralPath when retrieving the files in the source folder (or on the destination at all as it happens).

I can fix this, but it will need a code change.
