ext is the extended filesystem (English: Extended file system, abbreviated EXT or EXT1), also translated as an extended filesystem, a filesystem, published in April 1992, is the first file system for the Linux core. Uses the Unix file system (UFS) metadata structure to overcome the poor performance of the Minix file system. It is on Linux, the first file system implemented with virtual file system, supported for the first time in Linux core 0.96c, with a maximum of 2GB file system
It consists of three large files: Ext-all.css,ext-base.js,ext-all.js (including all class libraries, which you can delete as needed.) The official website provides this interface), when referring to the Ext class library, these three files are necessary.
It offers a rich, very beautiful look experience that has become a hot pursuit for many of the interface layer developers! Its core components basically cover the components we use to build the client.
Starting with EXT 2, the commercial version (for those for profit-oriented developers) is charged. This may affect some of his application prospects.
