1. Uploading.
   
   If the security prefix has been set to the current user, all the image files will be renamed and a prefix will be added the file names when uploading.
   
   If the original file names were named:
   
   Flower.jpg
   Holiday.jpg
   Kids.jpg
   
   and the current user has been set the security prefix: "Jack_"
   
   Then the resulting renamed files would be named in the server:
   
   Jack_Flower.jpg
   Jack_Holiday.jpg
   Jack_Kids.jpg 
   
    
2. Viewing
   
   If the security prefix has been set to the current user, the current user can only view the images whose name begins with his/her security prefix.
   
   In the screenshot1, the images whose name begins with "Jack_" will be displayed, the other images will be hidden.
   
3. Users with NO prefix are not limited by prefix restriction. For Admin/Power Users, allow them to view all files by simply not setting security prefix.
   
   
   
   
   

In some situations, the developers need to reename images based on the time the file was uploaded. With Cute Editor, you can easily rename images with a time date stamp the file was uploaded.

The unique identifier used in the generated file name has the following format:

YYYYMMDDHHMMSS+3 Random numbers

Where YYYY, MM, DD is the year, month and day; HH, MM, SS is hours, minutes and seconds. 

This feature is turned off by default. But you can turn it on and off by using the following methods: 

1: Edit security policy file.

The security policy file (default.config, admin.config and guest.config) can be found in the /CuteEditor/Configuration/Security folder. In security policy file you can find the UseTimeStampRenameUploadedFiles element. By default, it contains the following value:

<security name="UseTimeStampRenameUploadedFiles">true</security>

You can modify the UseTimeStampRenameUploadedFiles element to meet your own requirements.

For example:
<security name="UseTimeStampRenameUploadedFiles">true</security>
