    How are you opening this file when you write to it?  If you open it as Append, it will tack any changes on the end of the existing file.  If you open it as Output, it will overwrite the existing file.  This might be your problem.  John

    To delete a line, you'll have to read the whole file into a variable, and output the whole file again... just missing out the line you don't want any more.

    Regarding records, how exactly are you saving them?

    this is how im saving them:
    open app.path & "\StaffInfo.txt" for append as #1
    write #1, staff.name, staff.dateofbirth
    close #1

    i know how to save and how to load, i just cant overwrite

    Well... what you do is Load it, to a Replace on the line you want, ie

    'load the file into sContents, then...
    sContents=Replace(sContents,"my line" & vbCrLf, "")
    'then save the whole lot to the file again (WITHOUT using append)

    why not output them all into a database?

    that way you can delete records very easily and output the results to a textfile if that's what's needed?
