What you said upstairs is wrong. If I just used ren, would I still post it here to ask? Don't you think about it

If simply changing "*.rmvb" to "*.flv", you can directly use "ren *.rmvb *.flv".

He is going to change the RMVB video file into a flash file. Just renaming it is a bunch of unexecutable junk files

That's not called renaming at all, it's purely format conversion. Then the initial title was off-topic.

The landlord's problem really can't be solved just by changing the name. It is suggested that the landlord should first make up for computer knowledge.

The title of the owner and the content of the post do have some discrepancies, which can be seen as a format conversion.



@Echo off

for /f "delims=" %%a in ('dir /s/b/a-d *.rmvb') do (mencoder.exe  -ffourcc FLV1 -of lavf -lavfopts "%%a" -o "%%~dpna.flv"
