Files on a new disk are typically stored in blocks known as allocation units or clusters. These blocks are fixed-size segments of disk space, which the file system uses to manage data efficiently. The size of these blocks can vary depending on the file system and the disk's formatting, but common sizes range from 512 bytes to several kilobytes. When a file is saved, it occupies one or more of these blocks, depending on its size.

Traditional file environment is not well suited to save data in them. They make it difficult to read the data as they are more unstructed.

They are 'file compression' utilities. Basically, when windows saves a file, it's saved in fixed 'blocks' of data. ZIP programs 'strip out' the unused spaces in these blocks - reducing the amount of space the file occupies on the hard-drive. The files are 'unzipped' when they're in use, then compressed again back for storage.
A file, the contents of which defines who can perform actions on a file or folder
The advantage is that while accessing a block that is stored at the middle of a file, its location can be determined by chasing the pointers stored in the FAT as opposed to accessing all of the individual blocks of the file in a sequential manner to find the pointer to the target block. Typically, most of the FAT can be cached in memory and therefore the pointers can be determined with just memory accesses instead of having to access the disk blocks.
