What’s This Error Anyway?
Error 0X00000589 (ERROR_NO_WILDCARD_CHARACTERS) is Windows’ way of saying “I asked for wildcards (like * or ?) and you didn’t give me any.” It shows up in command prompts, batch scripts, or anywhere an API call expects wildcard patterns — think FindFirstFile or CopyFile with a pattern. You’ll see it if you’re running something like dir *.txt and the shell gets confused, or more commonly inside a script where you passed a literal path but the code needs a pattern.
I’ve seen this mostly with older admin scripts, especially ones that use cmd /c or call into Windows APIs directly. The culprit is almost always quoting — either you’re missing quotes around the wildcard, or you have extra quotes that make the wildcard literal. Don’t overthink it. Start with the quick checks.
Quick Fix (30 seconds): Check Your Quotes
Before you touch anything else, look at the command or script line that throws the error. Most of the time, the wildcard is sitting inside quotes and Windows treats it as a literal character. Example that fails:
copy "C:\folder\*" D:\backup\That * inside quotes is not expanded. Fix by moving the quote outside the wildcard:
copy C:\folder\* D:\backup\Or if you need quotes for spaces, use them around the whole path including the wildcard, but that usually breaks. The safe bet is to quote just the directory part without the wildcard. For PowerShell, same story:
Get-ChildItem "C:\folder\*" # BAD
Get-ChildItem C:\folder\* # GOOD (if no spaces)If your path has spaces, you need to escape the wildcard differently. In cmd, you can use " to break out, but that gets messy. Better to use cd into the directory first:
cd "C:\My Folder"
dir *That avoids the quoting mess entirely. This solves about 80% of cases. If that didn’t do it, move on.
Moderate Fix (5 minutes): Check for Hidden Characters
Sometimes the wildcard looks fine but there’s a sneaky non-breaking space or a Unicode character that isn’t an asterisk. I’ve seen this with copy-pasted commands from web pages. The fix is to retype the wildcard manually. Delete the * or ? and type it fresh. Also check your script’s encoding — if the script was saved in UTF-16 or with a BOM, some shells choke.
Open the script in Notepad++ and set Encoding to UTF-8 without BOM. While you’re at it, look at line endings — Unix line endings (LF) can cause weird issues in cmd. Convert to CRLF. This matters more than you think.
If you’re using PowerShell, run this to see what the script actually sees:
Get-Command yourscript.ps1 | Select-Object -ExpandProperty ScriptBlockThat shows the raw text. Look for odd dots or spaces. Don’t use Get-Content because it might hide the issue.
Another thing: check if you’re in a restricted language mode in PowerShell. Get-ExecutionPolicy and $ExecutionContext.SessionState.LanguageMode. If it’s ConstrainedLanguage, some commands might behave differently but this specific error isn’t typical. Still, check if you’re on an old PowerShell version — upgrade to 5.1 or later. PowerShell 7 is based on .NET Core and handles wildcards differently in some edge cases, but the error mostly comes from Windows API calls.
If you’re still stuck, move to the advanced section.
Advanced Fix (15+ minutes): Registry and API-Level Causes
Rarely, the error comes from a system call where the wildcard pattern is expected in the registry or a driver configuration. For example, some backup tools or file system filters pass a pattern that’s empty. If you see this error consistently with a specific application, check the application’s configuration files — look for any path patterns that might be empty strings.
One real-world trigger I recall: a scheduled task that runs a batch file with for /r loop and the path variable is empty. Here’s the pattern:
for /r "" %i in (*.log) do ...If the directory is empty, *.log won’t match and some older Windows versions throw 0x589 instead of just doing nothing. The fix is to add a check:
if exist *.log (for /r "" %i in (*.log) do ...)That prevents the call entirely.
If it’s not a script, look at the Windows API call in question. Use Process Monitor (ProcMon) from Sysinternals to see what file or registry access fails when you get the error. Filter by the process name and look for “NO WILDCARD” in the result column. That will point you to the exact path or pattern. Then you can fix the source — it might be an environment variable that’s not set, or a registry value that’s empty.
For registry, check HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts — sometimes stale entries cause issues with wildcard handling, but that’s a shot in the dark. Only go there if ProcMon shows a registry access failure.
Also, if you’re on a network share, check that the server isn’t returning an error that gets misinterpreted. Try running the same command locally to rule that out. I’ve seen cases where SMB1 vs SMB2 differences cause weird errors.
If nothing else, reboot. Yes, I know, sounds cliché. But if a system service has cached a bad pattern, a reboot clears it. That’s the oldest trick in the book and it still works.
Wrapping Up
Most people hit the quote issue. Fix that first. Then check for hidden characters. If you’re still stuck, get ProcMon and trace it. Don’t waste time messing with the registry until you know exactly what’s failing. This error is almost never a hardware problem — it’s always a logic problem in how the wildcard is passed. Stay calm, check your syntax, and you’ll get it sorted.
