What is a .FTS file?
An FTS file is a type of data file used by the Windows Help system, which is a feature included in older versions of the Microsoft Windows operating system. The "FTS" stands for Full Text Search Index. This file is automatically created by the Windows Help software when a user searches for specific text within the help documents, provided that the keyword indexing feature is enabled.
The purpose of an FTS file is to store a detailed index of every location within the help files where the searched text appears. By doing this, it helps the system to perform any future searches for the same text much more quickly and efficiently, because it can refer back to this index instead of scanning all the text again.
To open an FTS file, you would typically use the Microsoft Windows Help program. However, it's important to note that Microsoft has discontinued this program in more recent versions of Windows. In older versions of Windows where it is still available, Windows Help is integrated into the operating system, so no additional software is needed to open FTS files. If you are using a newer version of Windows that does not support Windows Help, you might encounter difficulties in opening FTS files.
