Filetype is the programming of a computer, and it is the instruction of a search engine, which can find out the files currently included in the search engine.

The usage of filetype of search engine is filetype: file type keyword, and the return values are all keyword files of the specified file type.

In Baidu, the file types supported by filetype are: ppt, xls, doc, rtf, pdftxt.

In google, the supported filetype file types are ppt document, excel data document, word document, WordPad document, flash, pdf document and google earth coordinate document.

For example, you want to search for certain files, such as a PPT file about pandas: filetype:ppt Panda.

Precautions for using the filetype command:

File types are used to search for specific file formats. Both Google and Baidu support the filetype instruction. For example, a Google search for "filetype:pdf search skills" will return all pdf files containing keyword search skills.

But it should be noted that when we use the filetype command, the following file type must be the above file type (Baidu and google are different). In addition to entering the file type, we also need to enter keywords.

For example, if we input the instruction filetype:ppt, we can't find what you want by using filetype:ppt, because the search engine doesn't know what you want.
