Might I suggest you something amigo...The .bik to .bk2 encoding batch you are using might be a troublesome one...
Your batch file will just delete all the .bik files after the encoding...But its a common error that some .bik files aren't supported then your encoder will simply delete it too...
Use this :
Code:
FOR /F "usebackq delims=" %%i in ( `dir /b /s *.bik` ) do ( IF EXIST "%%~dpni.bk2" ( DEL "%%i" ) )
Instead of:
