File format object classes provide access to data stored within files of certain types. For example, the IDLffXMLSAX and IDLffXMLDOM classes provide access to attribute information stored in .xml files. The IDLffLangCat class ... provides access to XML data. However, this object allows you to access XML data stored in language catalog files (.cat), which can be used to support internationalization. File format objects may or may not have a graphical element that can be displayed.

When markup advocates attempt to convince an audience of the value of breakthroughs such as XML, they almost invariably give the example of the proprietary, binary file format -- and the most common bogey is the saved word processor file. Discussion of precursors to XML file formats usually include comma-delimited file formats, which are very often used for import and export of spreadsheets and databases. The saved files from front-office, or just office tools -- word processors, spreadsheets, presentation software, contact managers, and the like -- hold an inordinate amount of the data that represents users' knowledge. Your notes, memos, proposals, analyses, plans, and organizational tools are on the front line of knowledge management. When you upgrade or migrate any such software, one major concern is whether the new arrangement will import your old files. When you perform backups you usually start with these office files.

All data structures that the object file format defines follow the ``natural'' size and alignment guidelines for the relevant class. If necessary, data structures contain explicit padding to ensure 4-byte alignment for 4-byte objects, to force structure sizes to a multiple of 4, and so forth. Data ... have suitable alignment from the beginning of the file. Thus, for example, a structure containing an Elf32_Addr member will be aligned on a 4-byte boundary within the file. For portability reasons, ELF uses no bit-fields.

GIF, or Graphics Interchange Format, is a popular file format for web use and other Internet applications. These files are typically small in size and load quickly in Internet browsers. GIF files are limited to a maximum of 256 colors.

It is possible to place H.264 and AAC streams into the traditional FLV file, but Adobe strongly encourages everyone to embrace the new standard file format. There are functional limits with the FLV structure when streaming H.264 which couldn’t be overcome without a redesign of the file format. This is one of the reasons Adobe is moving away from the traditional FLV file structure. Specifically dealing with sequence headers and enders is tricky with FLV streams. Adobe is still working out if it’s possible to place On2 VP6 streams into the new file format.

If you use Photoshop for your digital photo editing then PSD is probably the most important file format that you need to know. A PSD file is a Photoshop file format and is your best option when working on digital photos for two main reasons. First of all, PSD files allow the user to work in layers and channels and save work being done without compressing the layers. This of course usually results in a large file size. Secondly, PSD files do not lose image quality as you work on images because there is no compression when the file is saved resulting in lost data. It is always best to save your work as a PSD file until your image is finished and then you can save into the format most appropriate for your project.
