What is an AST file?

AST files mostly belong to Photoshop by Adobe. AST file extensions can refer to Ability Spreadsheet Template files used in Ability Office software.

Main Use: AST files are used by Ability Office Software in the creation of multiple, Ability Spreadsheets (AWS) files using the same template. Ability Spreadsheet program which is a part of the Ability Office suite is the program used to open AST template files. One can also visualize the various components of the AST file using any ZIP file extractor like 7-Zip. The WordPerfect word processor from Corel's WordPerfect Office Suite, apart from the default WordPerfect Template (WPT) files, can also access AST template format files.
Other Uses: Adobe products such as Photoshop and Acrobat DC also use AST files as Adobe Color Separations Table files to export data into PDF format or a different program. AST files can also refer to Audio Stream files used in Nintendo's GameCube and Wii video game consoles. AstorGrav is a solar system software program that can run simulations depicting the motion of several astronomical objects under the gravitational influence of other objects around them. The data belonging to these simulations is also stored in an AST format. AST files were also used as ClarisWork Assistant files on AppleWorks office suite for building calendars, presentations, and business cards.

AST file format:

Every file has a defined file format, i.e. how the data is arranged in the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. If there are problems opening a file, you must first determine the file format used. Below is our analysis of the AST files:
