I am searching all the exe,dll or both files in a particular folder. I wish to copy the data in the same way in txt file as it is displayed in the textboxes like (FileName| Path.....) pair value.File.WriteAllLines(@"C:\BigB.txt",files.ToArray()); will copy only the path in BigB.txt but I can't get them in the way shown below

File1.exe Path1File2.exe Path2......

since I can't use something like File.WriteAllLines(@"C:\BigB.txt,Path.GetFileName(files) + files.ToArray())"

Though I have an idea of copying all the filenames in another list, like this

List<String> filename =newList<String>(); filename.AddRange(files);

and then copying the data into txt file with the help of both the lists. But then again how to go through each entry one by one ? :|
