Question

How can I find out if a file has finished copying c#

Asked by: ttnetworks

I am putting together an application that needs to watch several folders and once they have hit a certain size / file count, perform an action.

I intend to use the FIleSystemWatcher to do this, however I have one outstanding query. If a file is being copied into that folder, I need to know when the copy process has finished, and also check that no other processes are accessing the files.

Can I somehow extract that information from the Windows API ? This application initially only needs to work with local files and folders.

Thanks

Andrew

For the part of your question about needing to check if no other processes are accessing the files, I use this:

   

   public bool FileIsLocked(string strFullFileName)
       {       
           bool blnReturn = false;
           System.IO.FileStream fs;
           try
           {
               fs = System.IO.File.Open(strFullFileName, System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Read, System.IO.FileShare.None);
               fs.Close();
           }
           catch (System.IO.IOException ex)
           {
               blnReturn = true;
           }
           return blnReturn;
       }
