SQL Anywhere is a relational database management system originally developed by Sybase and later associated with SAP. It creates aaa files during normal operation to hold temporary data used while processing database tasks.
The files are temporary working data rather than a standalone database format. SQL Anywhere manages them internally, and their contents are not intended for direct use or long-term storage. This file type is associated with SQL Anywhere on Microsoft Windows, Linux and Unix, and Apple macOS or Mac OS X.
aaa files are created and used internally by SQL Anywhere, so they cannot normally be opened manually with a text editor or another general-purpose application.
Use the SQL Anywhere database software that created the file. If the file remains after the related database operation has ended, the software should be allowed to manage it rather than treating it as a normal document.
There is no normal conversion method for an aaa file. It contains temporary working data for SQL Anywhere, not data intended for export to another file format.
To obtain reusable data, use SQL Anywhere's database export or data-transfer features on the relevant database instead of converting the temporary file.

Ransomware encrypted file

The aaa file extension is also known to be used for one of the 2015 variants o TeslaCrypt ransomware.
This malicious software encrypts and locks users data and renames the extension to one of the many options, including aaa.
TeslaCrypt also leaves instructions and ransom demands in a special text file "HELP_RESTORE_FILES.txt" file found in affected folders.
Tools like TeslaDecore may perhaps help you with unlocking your data even without paying the ransom.
There is no way how to convert affected the files, you first have to purge the virus from your system and then hope for some decoding tool to appear on internet.
