File system Template:Verth Template:Verth Template:Verth Template:Verth Template:Verth Template:Verth Template:Verth Template:Verth Template:Verth Template:Verth

All widely used file systems record a last modified time stamp (also known as "mtime"). It is not included in the table.

Individual file systems may record additional special types of date and time stamps. For example, the specification of ISO 9660 includes a "File Expiration Date and Time" and a "File Effective Date and Time".[12]

Limits

While storage devices usually have their size expressed in powers of 10 (for instance a 1 TB Solid State Drive will contain at least 1,000,000,000,000 (1012, 10004) bytes), filesystem limits are invariably powers of 2, so usually expressed with IEC prefixes. For instance, a 1 TiB limit means 240, 10244 bytes. Approximations (rounding down) using power of 10 are also given below to clarify.
