    Is there a way to know if a file REALLY exists?

      If a large file is being copied into a diretory. FileUtilService.Exists will return TRUE. That only indicates a 'directory entry' exists, not that the file is there and available.

       

      Is there a way to get that information? If you get Windows' file proeprties it will tell you that the file is 'locked', but I do not see any FileUtilService to get that info.

       

      Is there a solution to that?

       

      TIA

          Possibly you could do it in an Execute Script step using methods available on the Java File object.

            Hi Steve,

             

            That is exactly what I ended up doing.

            For future reference here is the script code I used, seems to do the job:

             

            File filename =pathToFile( patExecContext.getProcessDataStringValue("/process_data/@filepath"));
            boolean doesFileReallyExists = filename.canWrite();
            if (doesFileReallyExists ) {
                        try {
                            ran = new RandomAccessFile(filename , "rw");
                             try { 
                                if (ran != null) ran.close();
                             }  catch (IOException ioe) {
                             }
                        } catch (Exception ex) {
                            doesFileReallyExists = false;
                       }
             }
            patExecContext.setProcessDataBooleanValue("/process_data/@fileExists", doesFileReallyExists );

             

            One caveat of that script is that LCES needs R/W access to the file/document.
