File size is a measure of the amount of memory being used to store data of storage, either logical or physical, required for a file(s) or dataset. It

The logical amount corresponds to the space required to represent all the information in the file. The physical amount is the space actually occupied on a storage device. The physical size may differ from the logical size due to the type of compression techniques employed and the file system used.

Size is most commonly measured in various formsterms of bytes (eg. KiloByte, MegaByte etc8-bit) bytes. The The SI prefix denotes the factor of which the amount should be multipledfactor of which the amount should be multiplied (eg. Kilo = 1000 or 1024, Mega = 1,000,000 or 2^20, etc).

The actual physical amount of the disc space varies due to the type of compression techniques employed and the file system used. Some Some of the most typically used units of file sizessize are as follows:

  • 1One Byte = 8 bitbits
  • One Kilobyte = 1 KB = 1,024 = 2^10 bytes
  • One Megabyte = 1 MB = 1,048,576 = 2^20 bytes
  • One Gigabyte = 1 GB = 1,073,741,824 = 2^30 bytes
  • One Terabyte = 1 TB = 1,099,511,627,776 = 2^40 bytes

The logical amount corresponds to the space required to represent all the information in the file. The physical amount is the space actually occupied on a storage device. The physical size may differ from the logical size due to the type of compression techniques employed and the file system used.

Size is most commonly measured in terms of (8-bit) bytes. The SI prefix denotes the factor of which the amount should be multiplied (eg. Kilo = 1000 or 1024, Mega = 1,000,000 or 2^20, etc). Some of the most typically used units of file size are:
