How can there be so many file formats on the web?

What do you say about this question? Because different software or companies want to show that they are different from everyone, some files are generated by estimates, and some are generated for the purpose of selling a software, and they can't be read without their software. There are many reasons for this, in fact, there are not many common file formats for DOS, but now there are more and more, which is simply complicated, so there are more and more functions of many ** tools.

Not only are there many ** or movie formats, but there are also many ordinary document formats.

The RM format is not the most popular! Just shuttle between the Heng Sedan Royal network! Because the RM format is compressed to the extreme by the sail bucket, it can ensure its picture quality format, which is easy to spread on the Internet, because today's Internet speed is not very fast, so the RM format was born!!

In fact, unification will cause a lot more trouble.

The attributes and uses of each format are also different, each with its own characteristics, and it is the purpose to use it in a targeted manner.

RMVB, which has a high compression ratio, works very well.

There is no best, only better.

Common file formats are:

1. doc: word document.

The doc format should be familiar to many friends, a document format generated by word office software, which is almost a must-have software for office workers.

In addition to word software, you can also use a word viewer to view, and many word viewers have a defect in that they can't do doc files, so if you want to better do doc files, you still recommend practical word software.

2. RAR: Compressed package.

The main advantage of RAR is that it is possible to split the file compression target into multiple files, and it is easy to extract the source file from such a split compressed file. RAR also supports compressing all files into the same data area to increase the compression ratio, and can also add redundant repair information to RAR, which can repair the compressed package when the file is corrupted but the repair information is good enough.

3. HTML: web page.

The html-formatted file is actually a hypertext markup language file, which is the suffix name. html or. The htm is an HTML file.

4. zip: compressed package.

The ZIP file format is a file format for data compression and document storage, originally known as deflate, and was invented by Phil Katz, who published the format in January 1989.

5. exe: installation package.

exe is a file extension for the executable file format, an executable is a file that contains a program, that is, a specific type of file that can be executed or run as a program in a computer, an executable can be run by a program in Microsoft DOS or Windows by a command or a double-click.

6. PDF: PDF document.

PDF stands for Portable Document Format, Chinese translation is a portable document format, based on the Postscript language image model, no matter what kind of printer can ensure accurate color and printing effect.

9. TMP: temporary file.

TMP, TEMP, and TMP files are temporary files generated by various software or systems, which are often referred to as junk files. The temporary files generated by Windows are essentially the same as virtual memory, except that temporary files are more targeted than virtual memory and serve a program alone.

10. XLS: Excel worksheet.

XLS file, which refers to Microsoft Excel worksheets, is a more common spreadsheet format. It was developed and popularized by Microsoft Corporation.

11. txt: notepad.

The Han nationality is a big hybrid nation, miscellaneous, there is no Han nationality at all, those who do not believe it will draw blood from the Han people from all over the country to test it, the genes of the Han nationality are tens of thousands of genes, only the blood of each ethnic minority is the same

The file formats are generally *** format, RMVB format, and ABI format.

There are many types of video files, such as vob, rmb, mpg, mpg, etc.

Because the needs are different and the uses are different, some formats are suitable for dissemination, so it is necessary to use a format with a smaller preservation size, and some formats are suitable for preservation, so it is necessary to use some formats with clearer preservation effects, and different formats may also be some historical reasons, some have been eliminated and some have not, and have been inherited.

Because there are many manufacturers, it is difficult to unify.

I've also encountered it, it may be a network problem, it may also be a bug, and a similar situation will occur when the network is good, and the other QQ number does not appear in this situation; There is also a problem with this QQ number private folder.,That's it.。

It may be a network problem, or it may be because the file size is too large, and the system automatically breaks it down into smaller files to send.

Maybe it's a network issue. But don't worry about that. Just receive the documents and you're good to go.

I've run into it too, but only one friend will ask me to take it 4 times at a time.

Some files are too large to be transferred at one time, and the system will split them up.

Maybe it's his problem.,More points and then the network card.,It's sent a few over.,That's it.,That's it.。

Hahahahahahaha

Just now someone said they liked me, and I just deleted him. Oh my God! I'm about to plant rice, and now that he has a crush on me, he will definitely want to trick me into going to his house, breaking buds, threshing grain, digging potatoes, harvesting peanuts, and drying black.

I'm not stupid when I think it's weird and beautiful, it's all from the village, I still understand this routine.

Haha Happy Lantern Festival!
