What is a .AS4 file?
The file extension .AS4 represents a type of file known as an askSam Backup File. This type of file is specifically created by a program called SurfSaver. SurfSaver is designed to help users save web pages as they browse the internet. The .AS4 file itself is a backup of another file type called .ASK, which is a database file used by the askSam software.
When askSam needs to update an older .ASK file to a newer format, it creates a .AS4 file. This backup file ensures that if there are any issues with the new format, or if the user needs to access the data in the original format, the original data is still available. Essentially, the .AS4 file acts as a safety net, allowing older versions of the askSam software to open and use the original database without problems.
To open an .AS4 file, you would typically use the askSam Systems SurfSaver software. This is the program that originally creates these files and is equipped to handle their format.
If you find that you do not need to revert to older versions of the askSam software, or if you no longer need the backup created during the update process, it is safe to delete .AS4 files. This can help free up storage space on your computer.
