DOS学习入门 & 精彩文章（教学室） » [Help] A question for the batch file experts

How can I identify a file's extension in a batch file? For example, I have 2 files, one is .htm, the other is .jpg. I want to delete the *.htm file — how do I identify the extension?

It seems just using dEL *.htm is OK

This seems like looking for the horse while sitting on it! You've already written the extension in your question, so why are you still asking how to identify it? Can't you just type it in! Too strange! It's like asking, "Comrade Wang Weibing, what's your name?" Heh! The poster above didn't find it strange at all! He answered, "use del *.htm" — that's kind of like helping by saying, "Oh! You mean Wang Weibing! His name is Wang Weibing!"
