Thread: How to reduce the size of a gmapsupp.img file on a card???

"The gigabyte (/ˈɡɪɡəbaɪt/ GIG-ə-byt or /ˈdʒɪɡəbaɪt/[1]) is a multiple of the unit byte for digital information. The prefix giga means 10^9 in the International System of Units (SI). Therefore, one gigabyte is 1000000000bytes. The unit symbol for the gigabyte is GB.

This definition is used in all contexts of science, engineering, business, and many areas of computing, including hard drive, solid state drive, and tape capacities, as well as data transmission speeds. However, the term is also used in some fields of computer science and information technology to denote 1073741824 (1024^3 or 2^30) bytes, particularly for sizes of RAM. The use of gigabyte may thus be ambiguous. Hard disk capacities as described and marketed by drive manufacturers using the standard metric definition of the gigabyte, but when a 500-GB drive's capacity is displayed by, for example, Microsoft Windows, it is reported as 465 GB, using a binary interpretation.

To address this ambiguity, the International System of Quantities standardizes the binary prefixes which denote a series of integer powers of 1024. With these prefixes, a memory module that is labeled as having the size 1GB has one gibibyte (1GiB) of storage capacity."

Do NOT assume that if you have X amount of bytes available (claim by any memory product), you can use that exact amount. Formatting will reduced it.

Not ALL storage products will give the same "maximum" amount. If the product is defective, formatting will "locked out" the bad area thus giving you less storage.
