DEVELOPING COLDFUSION 9 APPLICATIONS

Using External Resources

Example code

Rename a file

<cffile action="rename" source="c:\files\memo\KeyMemo.doc"

destination="c:\files\memo\OldMemo.doc">

<cffile action="copy" source="c:\files\upload\KeyMemo.doc"

destination="c:\files\backup\">

Delete a file

This example sets the ReadOnly flag bit for the uploaded file:

<cffile action="Copy"

source="c:\files\upload\keymemo.doc"

destination="c:\files\backup\"

attributes="ReadOnly">

Note: Ensure that you include the trailing slash (\) when you specify the destination directory. Otherwise, ColdFusion

treats the last element in the path as a filename. This rule only applies to copy actions.

Reading, writing, and appending to a text file

In addition to managing files on the server, you can use the cffile tag to read, create, and modify text files. As a result,

you can do the following things:

• Create log files. (You can also use

• Generate static HTML documents.

• Use text files to store information that can be incorporated into web pages.

Reading a text file

You can use the

tag to read an existing text file. The file is read into a local variable that you can use anywhere

in the application page. For example, you could read a text file and then insert its contents into a database, or you could

read a text file and then use one of the string replacement functions to modify the contents.

Read a text file

Create a ColdFusion page with the following content:

Ready to read the file:<br>

<cffile action="read"

file="C:\inetpub\wwwroot\mine\message.txt"

variable="Message">

Replace C:\inetpub\wwwroot\mine\message.txt with the location and name of a text file on the server.

to create and write to log files.)
