Rename file with root explorer and it disappears. WHY?

[ahfu25]

I used root explorer to rename a file and it disappeared. Any reason as to why? I renamed it with .bak on the end

It disappeared from its original file location? I just renamed a pic and its still on the proper file location however I can't view it via any apps which is expected. The ".bak" extension just means "backup" so it's hidden from view/use.

It just disappeared. It was in the system/bin folder. It was a file that had to be renamed when using ktoonz kernal along with jelly bean and touchwiz
