Why the System.IO.File.Exists(fullpath) fails ?

[sudhaMurugesan]

Hi all,
I use asp.net with c#. I upload a file and save in a directory. I want to reopen the file so i check for file exists and then open it. But though the file exists, the file.exists(ful lpath) returns false . can anyone help me ? My code is here...
[CODE=C#]
string paths = this.MapPath(". ./TerminateDoc/Excel/" + fileName.Trim() );
/* paths = C:\\Inetpub\\ww wroot\\EIS\\Emp loyee.Web\\Term inateDoc\\Excel \\fi0002264Proo fDoc20080708101 851.txt */
if (File.Exists(pa ths)) // returns false ????
{
FileInfo fi = new FileInfo(paths) ;
Response.Clear( );
Response.ClearH eaders();
Response.Buffer = false;

Response.Append Header("Content-Disposition", "attachment;fil ename=" + System.Web.Http Utility.UrlEnco de(System.Text. Encoding.UTF8.G etBytes(fileNam e)));// + System.Web.Http Utility.UrlEnco de(System.Text. Encoding.UTF8.G etBytes(Path.Ge tFileName(paths ))));
Response.Append Header("Content-Length", fi.Length.ToStr ing());
Response.Conten tType = "applicatio n/octet-stream";
Response.WriteF ile(paths);
Response.Flush( );
Response.End();
}
else
{
this.RegisterSt artupScript("er ror", "<script>alert( 'The file is not uploaded or it has been deleted!');</script>");
}[/CODE]

Thank You

Does it return false even if you use

paths = C:\\Inetpub\\wwwroot\\EIS\\Employee.Web\\TerminateDoc\\Excel\\fi0002264ProofDoc20080708101851.txt;

for the path?

Sorry for late reply..
Thanks for ur reply. If i give the full path it works fine. But i cannot give the full path because while deploying it in the server, the root directory will differ.

Could you use Server.MapPath( filename) to get the full path?

Are you sure you have access to those paths/files?
.Exists() will fail on denied access as well as not existing I think.

I have access to that path.Thats why when i give the full path it can find the file. But still it fails.
Also Server.Mappath fails. I cannot trace out the reason. Please Help me!

I am thinking that it is a simple copy/paste type mistake. Like one of your strings doesn't contain the extension of the filename or something like that.
Have you set breakpoints and stepped through?
Maybe do a GetFiles() on the directory and manually verify that your filename is in there?
