.apf File Extension

Developer: Adobe Systems
File type: Profile File
You're here because you have a file that has a file extension ending in .apf. Files with the file extension .apf can only be launched by certain applications. It's possible that .apf files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .apf file?

The APF file extension is a data format associated to Adobe programs. APF files were developed by Adobe Systems. These files are also known as Adobe Profile File or Adobe Protected Format. These files contain a digital certificate or identification and signature used to authorize and identify a source of information. A digital signature consists of a handwritten name, a logo or other graphic, or text explaining the purpose of the signature. It also allowed adding graphics or pictures to the digital signature. Another option was to create invisible signatures. Adobe's legacy certificate format has not been used after Acrobat 5. They can be upgraded in Acrobat to a newer certificate format. Acrobat 6 used PFX file or the Windows Certificate Store. Then Acrobat 9 dropped neither creating nor importing APF files. Files in APF format can be opened with Adobe Acrobat X in Mac Os, Linux and Microsoft Windows based Systems.

how to open a .apf file?

Launch a .apf file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .apf file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .apf files aren't yet associated with it. In this case, when you try to open a .apf file, you can tell Windows which application is the correct one for that file. From then on, opening a  .apf file will open the correct application.

Adobe Acrobat x

Adobe Acrobat x

Adobe Acrobat X is a PDF management software, which is a set of various applications for the use of Portable Document Format or PDF files. It allows a user to not just view PDF files but also create from scratch or through a template available on the program, manage, print, and share. The 10th version of Acrobat, which is called Adobe Acrobat X, was first introduced in the year 2010 on November 15. It has new cool features like “sandboxing” protection to secure PDF files for the later versions of Windows OS computers, particularly Windows 7, Windows XP, and Windows Vista. This version of Acrobat X is also made compatible with Mac OS, iOS and Android, but not with Linux. The newest version of Acrobat X is Adobe Acrobat XI, which is the 11th version, that was recently announced last October 1, 2012 and expected to be commercially available on October 15, 2012. It is packed with a graphical user interface that is originated from the 10th version for all desktop systems. However, it has new cool features such as the ability to export PDF files to Microsoft PowerPoint presentation file, integration of cloud services, and touch friendly capabilities for compact mobile devices.

a word of warning

Be careful not to rename the extension on .apf files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .apf. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
