What is AES file?

AES is a file encrypted using 256-bit AES key. Decoding the file required that user provides a password. AES is capable of encrypting any type of data. Encrypted files are not significantly larger than the input files. Encrypted files can be used to securely exchange information between parties and preventing third party from accessing the file data. Typically an AES-encrypted files have an added AES suffix, for example Document.DOC becomes Document.doc.AES.


Encrypting files is one of the most secure means of sending information. Https protocol also uses encryption. Decrypting an encrypted data is not impossible but requires so much time and resources that is often not feasible, and thus using AES is considered secure.

Programs which support AES file extension

The following list contains programs grouped by 3 operating systems that support AES files. Files with AES suffix can be copied to any mobile device or system platform, but it may not be possible to open them properly on target system.

The solution to this problem is very simple. Download AES Crypt and install it on your device. The full list of programs grouped by operating systems can be found above. The safest method of downloading AES Crypt installed is by going to developer’s website (Packetizer, Inc.) and downloading the software using provided links.

Step 2. Verify the you have the latest version of AES Crypt

Update software that support file extension AESIf you already have AES Crypt installed on your systems and AES files are still not opened properly, check if you have the latest version of the software. It may also happen that software creators by updating their applications add compatibility with other, newer file formats. This can be one of the causes why AES files are not compatible with AES Crypt. The latest version of AES Crypt should support all file formats that where compatible with older versions of the software.

Step 3. Set the default application to open AES files to AES Crypt

After installing AES Crypt (the most recent version) make sure that it is set as the default application to open AES files. The next step should pose no problems. The procedure is straightforward and largely system-independent

Associate software with AES file on Windows

The procedure to change the default program in Windows

  • To finalize the process, select Look for another app on this PC entry and using the file explorer select the AES Crypt installation folder. Confirm by checking Always use this app to open AES files box and clicking OK button.
Associate software with AES file on Mac

The procedure to change the default program in Mac OS

  • From the drop-down menu, accessed by clicking the file with AES extension, select Information
  • Find the Open with option – click the title if its hidden
  • From the list choose the appropriate program and confirm by clicking Change for all....
  • If you followed the previous steps a message should appear: This change will be applied to all files with AES extension. Next, click the Continue button to finalize the process.

4. Verify that your device fulfills the requirements to be able to open AES Crypt

If the systems has insufficient resources to open AES files, try closing all currently running applications and try again.

5. Verify that your operating system and drivers are up to date

Regularly updated system, drivers, and programs keep your computer secure. This may also prevent problems with AES Crypt Encrypted Format files. It is possible that one of the available system or driver updates may solve the problems with AES files affecting older versions of given software.
