        /* ALPHA RELEASE 1.1.2 BUG FIX
         * 
         * BUG DESCRIPTION:
         * 
         * This patch fixes the bug  that is encountered when a file has been 
         * detected to be designated and its file name already exists in the 
         * designation folder, the File Designation Scan overwrites the file 
         * inside the designation folder, creating a bug which deletes the file,
         * losing the said file permanently.
         * 
         * GITHUB Issue Link:  https://github.com/idclxvii/SharpFixAndroid/issues/1
         * 
         * Solution:
         * 
         *       Renames the file name and checks if the renamed file already exists.
         *       If it does, call this method recursively until there's no occurrences 
         *       of the current file name chosen. If the file doesn't exist yet, then 
         *       proceed the cut and paste procedures
         *
