On boot item there is blank extension

[malikawan]

Today when i open Apps for on boot maintenance here On boot item there is blank extension i thinks its a blank extension so i delete it and that time all my extension which is present in On boot Item will be deleted i m so worried about that then ii close the apps and open onboot.lst and that time i shocked when it is also blanked. But suddenly i think that i have a backup of onboot.lst so i happy again. i always create a back of all that type of files its my habit.
Now question is that what happened and how a blank extension come in On boot item any one have some idea about that.
May be its my mistake but its happen with me.and blank extension present in on boot item.

Sounds like you did a manual edit of onboot.lst and had a blank line in it.

You said that already.
It sounds like you had previously used an editor to edit onboot.lst and left a blank line.

May be but not confirm.
if i edit onboot.lst and left a blank line then it happened so i 90 % sure its my mistake
