A file with the extension of MOBI are used in the MobiPocket ebook reader. These files follow and Open eBook standard and use XHTML for text encoding. Readers can add blank pages to books along with free-hand drawings. Highlights, bookmarks, corrections, notes, can also be applied.
The MOBI file complies with the Open eBook stanrds in XHTML. This standard includes Java Script and frames, with SQL queries in native mode for embedded databases. The MOBI file format can be read by a host of applications for PDAs, Smartphones, PCs and Macs.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .MOBI file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .MOBI file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .MOBI file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
