Can't seem to write to a file

I am having difficulities writing to a file in an EA I am working on. I am using this code
Inserted Code
int handle = FileOpen("Filename.log",FILE_CSV|FILE_WRITE,";");  
      FileSeek(handle,0,SEEK_END);
      FileWrite(handle,content);  
      FileFlush(handle);
      FileClose(handle);

I know the program runs through these lines of code, but nowhere can I find a file called "Filename.log"

Any ideas as to what I am missing?

Just a few things.

1. the fileseek and fileflush commands are not needed in this case.
2. Make sure the content variable has a value. If there is nothing there nothing is written.
3. Make sure you look in the experts/files folder for the file.
4. If it is not there, check the journal for errors.

1. OK
2. It has a text string, a simple comment for the log file
3. found it
4.

Now the only thing is it is not appending to end of file like I thought it would, and I checked your comments in the other thread on appending to a file. it runs through my EA, and at several points I have it write a comment to the logfile, for debugging. I know it is writing cause I have it write to the file in the init function, and while it is waiting for a tick I checked, and the comment for init function was there, as soon as a tick comes the file is overwritten with the last comment I have in the start function of the EA.

Any Ideas?

if it is an existing file, make sure you open it with FILE_READ|FILE_WRITE|FILE_CSV

and in that case doing a file seek for the end of the file would be good.
