Directory cannot be renamed or deleted after editing a contained XML file

[dean-e-peterson]

If I edit an XML file with XML Tools installed, I cannot rename or delete the directory containing that file even after closing the file. I have to close Notepad++ to rename or delete the directory. To reproduce:

1. Create a directory.
2. Copy an XML file into that directory.
3. Open the XML file in that directory in Notepad++.
4. Make an edit to the XML file. (Example, add and remove a space.)
5. Save the XML file.
6. Close the XML file in Notepad++.
7. Try to delete the file. It succeeds.
8. Try to rename the directory from Windows Explorer. It fails, saying "Folder In Use: The action can't be completed because the folder or a file in it is open in another program ... Close the folder or file and try again."
9. Try to delete the directory from Windows Explorer. It fails, saying "Folder In Use: The action can't be completed because the folder or a file in it is open in another program ... Close the folder or file and try again."

Versions:

• Windows 10 Professional
• Notepad++ v8.4.5 (32-bit)
• XML Tools 3.1.1.13

Other notes:

• SysInternals Process Explorer did not see a Directory handle to the directory under process notepad++.exe. However, looking at the notepad++.exe process properties in Process Explorer showed the directory as the Notepad++ current directory.
• The same behavior did not happen without XML Tools installed. I removed the XML Tools plugin from Notepad++ Plugins Admin and repeated the steps above. Without XML Tools installed, I was able to edit the file in Notepad++, close it, and rename and delete the directory successfully.
• I'm a developer but not a C/C++ developer. I debugged a little. I think the cause is setting the current directory in ToolsXmlValidate.cpp line 24, where performXMLCheck() calls _wchdir(currenPath). There is a similar call in XmlValidation() in the same file.
