Setting File and Directory Attributes

In Windows, you specify file attributes using the cffile attributes attribute. In UNIX, you specify file and directory permissions using the cffile and cfdirectory mode attribute.

Windows

In Windows, you can set the following file attributes:

ReadOnly
Temporary
Archive
Hidden
System
Normal

To specify several attributes, use a comma-separated list, such as attributes="ReadOnly,Archive". If you do not use attributes, the file's existing attributes are maintained. If you specify any other attributes with Normal, the additional attribute overrides the Normal setting.

Example: Setting file attributes

This example sets the archive bit for the uploaded file:

<cffile action="Copy"

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

  destination="c:\files\backup\"

  attributes="Archive">

Note

Make sure you include the trailing slash (\) when you specify the destination directory. Otherwise, ColdFusion treats the last element in the pathname as a filename.

UNIX

In UNIX, you can set permissions on files and directories for owner, group, and other. Values for the mode attribute correspond to octal values for the UNIX chmod command:

4 = read
2 = write
1 = execute

You enter permissions values in the mode attribute for each type of user: owner, group, and other in that order. For example, use the following code to assign read permissions for everyone:

mode=444

To give a file or directory owner read/write/execute permissions and read only permissions for everyone else:

mode=744
