Reset File Attributes - Set or Reset Read Only file attribute.

Introduction

I recently downloaded a project of 23 files which all had the readonly attribute set. Not wanting to change all 23 files manually I came up with this simple utility.

Background

CFileFind has a few members to test for IsDirectory(), IsDots() etc. I needed to Set or Reset the file attribute which can only be done using System::IO

Using the Code

The project has to be compiled with Common Language Runtime Support (/clr option). /clr can't be used with /MD or /MT, they have to be cleared from the project properties page.

The default starting directory is C:\Temp copy your files there. Or enter a new starting directory.

The following code shows the System usage:

#using &ltmscorlib.dll&gt
using namespace System;
using namespace System::IO;
using namespace System::Text;

The following code shows the routine that recursively counts the files:

// Recursively count the total number of files and those with ReadOnly Set.
void CurrentAttribute(String^ Path)
{
	CFileFind finder;
	String^ filename;
	String^ fullpath;
	CString szSearch(Path);	// convert String^ to CString
    if (szSearch.Right(1) != _T ("\\"))
        szSearch += _T ("\\");
    szSearch += _T ("*.*");
	// The search engine
	BOOL bWorking = finder.FindFile(szSearch);
	while (bWorking)
	{
		bWorking = finder.FindNextFile();
		Sleep(1);	// give it some time
		if(finder.IsDirectory())
		{
			filename = gcnew String(finder.GetFilePath());	// convert CString to String^
			if(!finder.IsDots())
				CurrentAttribute(filename);
		}
		fullpath = gcnew String(finder.GetFilePath());	// convert CString to String^
		if((!finder.IsDots()) && (!finder.IsDirectory()))
		{
			// Test Read Only
			if((File::GetAttributes(fullpath) & FileAttributes::ReadOnly) == FileAttributes::ReadOnly)
			{
				num++;
			}
		total++;
		}
	}
}

The following code shows how the ReadOnly Attribute is Set or Reset:

// Recursively scans the path
void Recursive(String^ path, bool bSetAttr)
{
	CFileFind finder;
	String^ fullpath;
	String^ filename;
	CString szSearch(path);	// convert String^ to CString
    if (szSearch.Right(1) != _T ("\\"))
        szSearch += _T ("\\");
    szSearch += _T ("*.*");
	// The search engine
	BOOL bWorking = finder.FindFile(szSearch);
	while (bWorking)
	{
		bWorking = finder.FindNextFile();
		Sleep(2);	// give it some time
		if(finder.IsDirectory())
		{
			filename = gcnew String(finder.GetFilePath());	// convert CString to String^
			if(!finder.IsDots())
				Recursive(filename, bSetAttr);
		}
		fullpath = gcnew String(finder.GetFilePath());	// convert CString to String^
		// Include only files
		if((!finder.IsDots()) && (!finder.IsDirectory()))
		{
			if(bSetAttr)
			{
				// Sets Read Only
				if((File::GetAttributes(fullpath) & FileAttributes::ReadOnly) != FileAttributes::ReadOnly)
				{
					File::SetAttributes(fullpath, static_cast<FileAttributes>(File::GetAttributes(fullpath) |
						FileAttributes::ReadOnly));
					Console::WriteLine("The file {0} is now Read Only", fullpath);
				}
			}
			else
			{
				// Resets Read Only
				if((File::GetAttributes(fullpath) & FileAttributes::ReadOnly) == FileAttributes::ReadOnly)
				{
					File::SetAttributes(fullpath, static_cast<FileAttributes>(File::GetAttributes(fullpath) ^
						FileAttributes::ReadOnly));
					Console::WriteLine("The file {0} is no longer Read Only", fullpath);
				}
			}
		}
	}
}
