Sending Sis via BT
==================
IF we r trying to send sis files via ir or bt we get an error saying "Unable to send protected Items" to overcome this pls try the following steps

Step 1:On FExplorer Go to Folder that your Sis or protected files are in it.
Step 2:Highlight the file and go to OPTION>>>FILES>>>RENAME now rename your files. for example if your file name is theme.SIS you rename it into theme.SIS.A
Step 3: on Highlighted file go to OPTION>>>SEND>>>VIA BLUETOOTH(or infrared)

now you send a protected file by your phone
