Definition. Data compression ratio is defined as the ratio between the uncompressed size and compressed size: [1][2][3][4][5] Thus, a representation that compresses a file's storage size from 10 MB to 2 MB has a compression ratio of 10/2 = 5, often notated as an explicit ratio, 5:1 (read "five" to "one"), or as an implicit ratio, 5/1.
File size. File size is a measure of how much data a computer file contains or, alternately, how much storage it consumes. Typically, file size is expressed in units of measurement based on the byte. By convention, file size units use either a metric prefix (as in megabyte and gigabyte) or a binary prefix (as in mebibyte and gibibyte).
ARC – Nintendo U8 Archive (mostly Yaz0 compressed) ARJ – ARJ compressed file. ASS, SSA – ASS (also SSA): a subtitles file created by Aegisub, a video typesetting application (also a Halo game engine file) B – (B file) Similar to .a, but less compressed. BA – BA: Scifer Archive (.ba), Scifer External Archive Type.
Kilobyte. The kilobyte is a multiple of the unit byte for digital information. The International System of Units (SI) defines the prefix kilo as a multiplication factor of 1000 (10 3); therefore, one kilobyte is 1000 bytes. [1] The internationally recommended unit symbol for the kilobyte is kB. [1]
In this convention, one thousand and twenty-four megabytes (1024 MB) is equal to one gigabyte (1 GB), where 1 GB is 1024 3 bytes (i.e., 1 GiB). Mixed 1 MB = 1 024 000 bytes (= 1000×1024 B) is the definition used to describe the formatted capacity of the 1.44 MB 3.5-inch HD floppy disk , which actually has a capacity of 1 474 560 bytes .
Because file size references are stored in eight instead of four bytes, the file size limit has increased to 16 exabytes (EB) (2 64 − 1 bytes, or about 10 19 bytes, which is otherwise limited by a maximum volume size of 128 PB, [nb 2] or 2 57 − 1 bytes), raised from 4 GB (2 32 − 1 bytes) in a standard FAT32 file system. [1]
On the other hand, a hard disk whose capacity is specified by the manufacturer as "10 gigabytes" or "10 GB", holds 10 × 10 9 = 10 000 000 000 bytes, or a little more than that, but less than 10 × 2 30 = 10 737 418 240 and a file whose size is listed as "2.3 GB" may have a size closer to 2.3 × 2 30 ≈ 2 470 000 000 or to 2.3 × 10 9 = 2 300 ...
10. fileWrite allows existing files to become "hidden", which may get deleted with lifecycle rule daysFromHidingToDeleting. Yes. Baidu Cloud. 2 TB. (6 GB free) [5] 4 GB free, 20 GB paid [6] Traffic limit is not stable, after going over the traffic limit, there is a bandwidth limited to 500 KB/s then 10 KB/s after another traffic limit.
