{
string name = Path.GetFileNameWithoutExtension(System.IO.Directory.GetCurrentDirectory() + "\\" + textBox1.Text.Trim());
string ext = Path.GetExtension(System.IO.Directory.GetCurrentDirectory() + "\\" + textBox1.Text.Trim());
string fname = name + " - Copy" + ext;
if(File.Exists(System.IO.Directory.GetCurrentDirectory()+"\\"+fname))
{
for(int i=2;i
{
fname = name + " - Copy("+i+")" + ext;
if (File.Exists(System.IO.Directory.GetCurrentDirectory() + "\\" + fname))

research on topic, if you want exact windows way..windows api reference c#
If looking for c# code
conststringfileName="C:\\1.txt";
stringfolderpath=Path.GetDirectoryName(fileName);
stringfilewithoutext=Path.GetFileNameWithoutExtension(fileName);
stringfileext=Path.GetExtension(fileName);
if(filewithoutext.EndsWith("-Copy"))filewithoutext=filewithoutext.Remove(0,filewithoutext.Length-7);
if(folderpath==null)return;
stringdestFile=Path.Combine(folderpath,string.Format("{0}-Copy{1}",filewithoutext,fileext));
intnum=2;
while(File.Exists(destFile))
{
destFile=Path.Combine(folderpath,string.Format("{0}-Copy({1}){2}",filewithoutext,num,fileext));
num++;
}
File.Copy(fileName,destFile);
