The file to close.


Always close a file after opening it. When you use the FileOpen function to open a file, the file stream is opened and contents are read from or written to it. The FileClose function closes the stream. If you do not close a file, the stream remains open; in that case, the operating system can lock the file, which results in the file not being usable until the server is restarted.


The following example checks to see if a file is still open and closes it.

    myfile = FileOpen("c:\my\custom\location\test1.txt", "read"); 
    while(NOT FileIsEOF(myfile)) 
    x = FileReadLine(myfile); 
    WriteOutput("#x# <br>"); 
<!--- Additional code goes here. ---> 
<cfif #myfile.status# IS "open"> 
    <cfoutput>The file #myfile.filepath# is #myfile.status#</cfoutput>        <br>
