Whenever a bad or corrupt file is recovered with a recovery software, why is each file of 1440 KB?
Many times, floppy disks turn bad and it becomes necessary to recover files by using a software like PC Inspector File Recovery or similar software.
Whereas the software recovers many of the files, it is noticed that each file is numbered as a cluster and each one has a uniform size of 1440 KB.
I would like to know as to why each file is shown as of the above size and whether the recovered and saved file actually occupies this much space on the Hard Disk?

This is just a best guess on my part. A typical high density floppy disk has a standardized storage capacity of 1.44MB. That equals 1440KB. It sounds like the recovery software is indicating it scanned all 1.44MB available on the floppy.

As far as how much space is set aside on your hard disk, that depends on a couple of things. If you're just reading the info it may never get to your HD. Instead, a temporary file is created containing the floppy's data. Most computers built within the past few years have enough random access memory (RAM) to store (cache) the data in the memory module rather than the HD. Only if you run out of RAM will the data make it to your HD.
Since a floppy holds 1.44MB, and if your computer has only 512MB RAM (which is very low these days), you can figure out how many floppies can be cached before worrying about the HD. (RAM is also used for other computer functions so floppy storage will be something less than 512MB divided by 1.44MB)
If you permanently transfer the data on a floppy to your computer then you get into the more confusing concepts of file systems, partitions, clusters and sectors. Depending on how much data one cluster can store and how much data is on the floppy will determine how many clusters are needed. This article gives a lot more info.
