What application file format does iPhone 3 support? How to view the file system of an iOS device in Windows

There are several popular formats for e-books on the Internet. The most popular: fb2, epub and PDF. DjVu is much less common, not everyone knows about it, but nevertheless it is a significant format, so I cannot ignore this topic on our website.

What is DjVU?

DjVu– a lossy image compression technology designed specifically for storing manuscripts, books, and magazines. It is especially appreciated in those areas where an exact correspondence between an e-book and a paper book is required.

Here are a couple of examples:

b) the student needs an electronic textbook in which the formulas will not be distorted. That is why there is a lot of educational literature in the DjVu format.

Plus, due to its algorithms, the DjVu format is more compact and convenient for fast transmission over the network.

How to open DjVu in iOS?

By default, DjVu cannot be opened on an iPhone or iPad. Therefore, it is necessary to have some third-party program from App Store. I will list the most interesting options.

Kybook Reader

A popular reader from Russian authors. She understands not only DjVu, but also a bunch of other formats. The only BUT: to add support for formats such as DjVu or CHM, you need to make an in-app purchase “Upgrade to Pro version”. The program is very worthy and if you need a combine for reading, then this is the best choice.

Unfortunately, the program has a problem with DjVu. Although it opens all files, it is not very comfortable to read them in the program. There is no scaling, DjVu processing looks like a hastily made feature.

For the sake of DjVu Pro version you shouldn’t activate it... But if you already have it, then why not use the function?

iBouqiniste

Another multifunctional e-reader with an old-school design: shelves like in the first versions of iBooks. iBouqiniste processed all test files correctly. The program makes page division and even in the “two sheets per screen” format, reading DjVu books is extremely convenient.

Happy reading everyone! :)

Apple has announced the app Files", which is designed to become a full-time file manager on the iPhone, iPod touch and iPad. Well, better late than never. In this material we will tell you about the main features of this application and answer the most interesting questions.

“Files” allows you to view and manage files (images, videos, documents, music and other data) that are stored in user folders both on the disk directly in the device and in cloud storage Oh. Program " Files"is an advanced version of the application.

On which iPhones and iPads is Files Explorer available?

Program " Files» available on iPhone, iPod touch and iPad under iOS control 11 and newer version.

Files application: appearance and management

The application interface is simple and minimalistic. We have a main window with folders and a left side menu with sources. The sources are Places And Tags.

Tab Places contains a menu with storage sources (iCloud Drive, Dropbox, etc.), files located directly on the iOS device itself. There is also a folder with recently deleted files (see screenshot below).

For convenience, it is possible to sort the list of files by name, date, size or tag. Also allow you to switch between views " Badges" And " Review».

There is a search and the ability to create subfolders.

At the bottom there are two main tabs " Review" And " Recent».

How to drag multiple files at once in the Files app

The nice thing is that Apple has implemented the ability to manage files using multi-touch gestures in Explorer. By selecting one file, you can easily add other documents by tapping on their icons or holding files with one finger to navigate through folders in Explorer.

When moving files, be careful, because once you start the operation, you will not be able to stop it or cancel all actions with one click. As an option, do not physically move the files, but assign tags to them.

What actions can be performed with files?

The application is not compatible with many file types. Despite this, some of them are available for preview, and some for editing. Despite the fact that the program almost always shows a preview of the data contained in the files, this does not mean that “ Files» will open this type. Often the application opens unsupported formats in third party programs. For example, launching Ulysses files opens the application associated with this format.

Images can be viewed and edited using standard markup tools. Text files You can also view only those that are opened by regular ones iOS programs. Files of unsupported formats are opened in third-party applications, of course, if they are installed. You can watch videos in AVI and MOV formats. As for music, a nice bonus will be support for high-quality tracks in . The archives are viewed, but they will not allow you to archive or unarchive the files.

In June 2017, at a developer conference, Apple showed a new application for its devices called Files.

Today I came across it in one of the folders on my iPhone and tried to remember how many times I have used this pseudo-cloud storage aggregator throughout its existence.

And I remembered: never. Do you remember that you have such an important program, according to Apple, on your iPhone or iPad?

The Files were doomed from the start

Let's remember what it all is, since this program takes up valuable space on our iOS devices.

By creating Files, Apple tried to make it easier to work with various cloud storage services, such as its iCloud, so that the user could manage all files from one program.

In fact, the “Files” application was supposed to perform the functions of a Finder, a kind of file manager, only not for local files on the device, but for pictures, photos, documents, archives and other things stored in the “clouds”.

At first, the application only worked with iCloud, and the guys from Cupertino promised that support for other storages would be added in the very near future. We didn’t lie: at some point it became possible to link your Dropbox account to “Files”.

And that was the end of it.

Neither Yandex Disk, nor Megashare - there is no way to attach any other storage to the application. I remember that I imagined the principle of “Files” to work like the standard “Mail” application, when there is a choice of many services.

Now is the time to admit that the idea of ​​collecting all network files in one place is good, but Apple implemented it very crookedly.

Judge for yourself:

• many files ( archives, for example) the application sees them, but cannot open them
• there are more advanced and convenient analogues from third-party developers, such as Documents from Readdle
• for most cloud storages there are separate applications in the App Store, which are an order of magnitude better than “Files”

A short survey of colleagues confirmed: “Files” is used in daily work completely useless application.

And in general, most programs and applications themselves perfectly save their data in iCloud directly, so that you can easily access them from another Apple device.

Well, don’t forget about Handoff.

What to do with this application?

Alas, the most realistic scenario for using the “Files” application is to upload audio tracks there in uncompressed flack format and listen to them, launching them one at a time: “Files” can play this format.

True, I'm not sure that anyone would want to bother like that.

Looks more realistic such a scenario: long tap on the icon, application deletion mode, tap on the cross, the “Files” application is deleted like a bad dream.

Do you think Apple will ever remember this unsuccessful experiment with a cloud storage aggregator? Or maybe you actively use this application every day?

Tell us in the comments how you do it. Maybe Yabloko did everything right?

Have a great day!

For anyone mobile device necessary file manager. On iPhones, this problem is especially acute, since Apple company is famous for its habits of creating devices that interact perfectly with all products of the American brand, but have very problematic contacts with third-party manufacturers.

There are two types of file managers for iPhone: programs that run on the computer, and applications that are installed on the iPhone itself. Naturally, their purpose is different, because computer utilities must ensure file transfer between the iPhone memory and the PC itself, but mobile applications needed to work with documents directly on the gadget.

Computer file managers

To transfer data from iPhone to PC and vice versa (in other words, to synchronize devices), a proprietary utility is usually used. Apple's iPhone file manager is called iTunes. Actually, this is the only official manager for iPhone. All other applications are developed by third parties.

iTunes main window

iTunes allows you to transfer files between your computer and iPhone, as well as all other Apple gadgets. You can transfer any data: it can be pdf documents, multimedia content, or contacts. You can transfer information between any devices, so iTunes is a universal solution for iPhone, MacBook, and many other devices.

In addition, it is a huge multimedia storage. There is always data here that will definitely be of interest to users: tens of thousands of films and audio tracks, applications, games and much more. All this can be transferred to your iPhone in just a few clicks.

In general, a lot of useful things can be said about this manager, which is what we tried to do in, and within the framework of this article we will continue to reveal the capabilities of other programs.

iTools File Manager

This is a third-party application for your computer, which is the best analogue of the official iTunes. This manager works much more stable than the original program and eliminates all sorts of glitches that are so characteristic of it. In addition, its functionality is somewhat broader: you can freely transfer PDF documents to iBooks, make program backups, and much more.

iTools main window

Uploading a photo via iTools is not difficult, because... An intuitive interface makes transferring files as simple and understandable as possible, even for a baby. Through this manager you can also synchronize your computer, iPhone and other Apple devices, which is very convenient from the point of view of organizing work.

One of the useful features of the application for working with data is the “Desktop” section. On the “Icons” tab, here you can work with the iPhone desktop and synchronize in real time. Folders can be created, moved, deleted, renamed, and various objects can be placed in them. There is an opportunity to reset backup copy worker files iPhone backgrounds to your computer to avoid data loss.

File manager for iPhone

Here the situation with the transfer and viewing of documents and objects, including pdfs, is somewhat different. The iPhone does not have a built-in manager, so you have to resort to third-party solutions to conveniently transfer any data between devices and transfer it within the gadget itself.

You can edit only a few types of data through the standard iFile viewer: txt, doc, docx, rtf, htm, html, sql. Through third-party solutions, you can edit pdf documents, repack archives, and do much more.

iFile - Screenshots

The application also has its own twist: you can transfer any files to your iPhone via the web interface. This is especially true for small documents in pdf format and archives that will reach the device “over the air” in a couple of seconds. Data can also be transferred in the opposite direction, you just need to activate the web server function in the phone itself. And then you can view any directory on your phone from your computer and transfer any document to it.

iStorage File Manager

To load information into the application, just copy the data to the Documents folder through any computer file manager. Then you should go to the same folder on your smartphone and select required file. The program will open it in a suitable editor and allow you to view and edit it. It is worth noting the convenient display of information on a mobile device.
