What is an ASO file?

ASO files mostly belong to Sage 50 Accounting. ASO files can have more than one function. In many cases they are used as bank statement files that follow the Open Financial Exchange format. These files store transaction data and are handled with accounting software like Sage 50 Accounting or Quicken.

Financial Data: They hold bank statements and transactions for use in financial management.

Bioinformatics Data: Some ASO files contain GenBank sequence information that works with tools such as NCBI BLAST to support sequence alignment descriptions.

Spectroscopy Data: Others store Raman spectroscopy measurements used with instruments like the TruScan RM Analyzer from Thermo Fisher (Thermo Fisher).

FilExt.com note: The actual purpose depends on the file’s origin. Confirm your source software to choose the right application for viewing or editing the file.

Flash (Cache File) by Adobe Systems Incorporated
Adobe Flash, initially known as Shockwave Flash and popularly called simply Flash, refers to both the Adobe Flash Player and to the Adobe Flash Professional multimedia authoring program. The Flash Player, developed and distributed by Adobe Systems (which acquired Macromedia in a merger that was finalized in December 2005), is a client application available in most common web browsers. ASO files are cache files used during Flash development, containing compiled ActionScript byte code. An ASO file is recreated when a change in its corresponding class files is detected. They are normally deleted after a compile.

ASO file format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. If there are problems opening a file, you must first determine the file format used. In the following you will find our evaluation of the ASO files:
