Rename File/Folder

shivanshub · August 11th, 2006, 02:00 PM

Hi pls help me. I want to rename folder/file in framework 1.1 but with out making any copy or temp file of original.

And other prob is I need to delete data from file and after that resize my file but with out making any copy (temp) of original file. Or by just using small size temp file but not to copy whole file.

Pls help by either by logical idea or by any built in class.

Thanking u.

hi
To rename a file you have no option then to copy the file and then delete the original file.You dont have a rename file command in .net1.1 or .net 2.0.

The way I rename files is by executing batch files. I do this only if the files are big else i will use the rename which create a copy first. Maybe renaming files with a batch file works for you.

Really?? What about the File.Move method??

System.IO.File.Move(oldFileName, newFileName);

This moves a file to another location. If the folder is the same, but the file name is different, you've effectively renamed the file, no?

Imar,

Sure. Using "System.IO.File.Move(oldFileName, newFileName)" will rename the file effectively. I thought that if the destination file has the same name that it will be removed by this command which the DOS command "move" will do. It is a bit confusing but after trying the "System.IO.File.Move(oldFileName, newFileName)" method I see that it does not remove the destination file.

It doesn't? In what kind of application are you using this? How does your code look like? I can successfully switch file names with the following code:

Code:

if (System.IO.File.Exists(@"C:\Piet.txt"))
{
  System.IO.File.Move(@"C:\Piet.txt", @"C:\Joop.txt");
}
else
{
  System.IO.File.Move(@"C:\Joop.txt", @"C:\Piet.txt");
}

Also, when I change c:\ in d:\ the file is moved to another disk...

Imar,

What I mean is as follows:
Lets say you have two files in the same directory "fileA.txt", "fileB.txt". I thought that if you use the method System.IO.File.Move(@"fileA.txt", @"fileB.txt") that it will replace "fileB.txt" with "fileA.txt". Now with the external DOS command MOVE in mind it is a bit confusing because the DOS MOVE command will replace the file.

I see.

Move in .NET throws an IOException when the destination file already exists.

You'll need to check for its existence and move it manually instead. A simple wrapper method could do that for you, so you can still use the familiar Move method syntax...

Cheers,

Imar
