I'm getting an IOException of "File system error" using FileConnection.delete() SOMETIMES when I try to delete a file even though FileConnection.exists() says it exists. I've looked at the docs and tried several things, but I'm still getting the error. Here are my exists() and delete() functions:

// I call these functions like this:

if (exists(filename))
       delete(filename);  // BAM!....IOException!!

        public static boolean exists(String qualifiedName) {
            boolean ret = false;
            String parsedQualifiedName = translateFilenameToRIM( qualifiedName );
            try {
                defaultDrive = pickADrive();
                FileConnection fconn = (FileConnection) Connector.open("file:///" + defaultDrive + parsedQualifiedName ); 
                ret = fconn.exists();  
                fconn.close();
            }
            catch (IOException ioe)
            {
            }
            return ret;
        }

  
        public static boolean delete(String name) {
            boolean ret = false;
            String parsedName = translateFilenameToRIM( name );
            try {
                defaultDrive = pickADrive();
                FileConnection fconn = (FileConnection) Connector.open("file:///" + defaultDrive + parsedName ); 
                if (fconn.exists())
                {
                    fconn.delete(); 
                } 
                fconn.close();
                ret = true;
            }
            catch (IOException ioe)
            {
                RimLogger.logErr("F Failed delete file: " + parsedName + " " + ioe.getMessage());  
            }
            return ret;
        }

Has anyone else seen this or can offer suggestions?

Thanks,

Hi Ferrol,
try this code

FileConnection fconn = (FileConnection) Connector.open("file:///" + defaultDrive + parsedQualifiedName ); 
if (fconn.exists())
    fconn.delete();

er, he's already doing it like that in his delete method.

does it fail with different files? or is the bug happening on the same filename? my first thought would be to check for differences in the filenames, or does your translateFilenameToRIM() method fail and return null?

[FerrolB]

I've checked the filenames and they are the same. The translateFilenameToRIM() function returns a valid string.

One thing that may be noteworthy is that the filename is "H^_testfile1.txt".

Does that seem ok?

Thanks,

strange it's intermittent if the filenames are the same but try it with a filename without any strange characters in (ie: ^)

Hi,
I dont think so it is due to the filename .. Bcoz if anything wrong with the filename it will throw an exception during a file connection itself and comes out.
It wont return fileexists == true. Check whether the fileConnection is a file or directory.
If it is directory means you can delete it if it is empty only.
