I know this thread is long dead, but to anyone reading it currently:
To get rid of any delimiters ("s or ';' or others) and just get
tab-delimited, use
DoCmd.TransferText acExportDelim, "",
"table_name","file_path_to_be_stored",False,""
The first pair of empty quotes is the parameter for delimiter and entering
"" seems to default to tabs - at least for me it does!
