At:Filename and extension name, filename represent the name of file, and extension name represents the type of file.Word2007 version
The pervious entitled doc of file extent, the later entitled docx of the extension of version, the pervious file extension of 2007 version of Excel
For xls, the entitled xlsx of the extension of version later.In addition to being used to distinguish different file types, file extension main function is
Determine which kind of software run when user wants to open this file by computer own system.Using this characteristic, by mentioning
The extension name of file is taken, we one can readily appreciate that the type of file.
File type is judged by file extension, it is not only convenient and efficient but also easily operated.But since extension name does not have
There is a unified organization management, so each software developer, can arbitrarily formulate the extension name of the file of oneself, because
This, judges that file type has certain probability of miscarriage of justice by extracting extension name.
In summary two methods good characteristic, when the printing cloud service module of cloud server receives a new office
After file, first by extraction document extension name, to primarily determine Doctype, if suffix name is mainstream office document(Journey
The office document of sequence setting), then just judging Doctype according to extension name at this time;If suffix name is not belonging to mainstream
