Two small streams, specified in [MS-OLEPS], hold the properties shown in Windows’ file details. Their names begin with the character U+0005. They live in the mini stream when small.

A property set
At each offset is a 32-bit size and a 32-bit count, followed by one pair for each property: a 32-bit identifier and a 32-bit offset, measured from the start of the set. Each value is a type word (the low 16 bits of a 32-bit value), followed by the data.
| Type | Value |
|---|---|
| 2 (VT_I2) | A 16-bit integer |
| 3 (VT_I4) | A 32-bit integer |
| 11 (VT_BOOL) | A boolean |
| 30 (VT_LPSTR) | A 32-bit length, then bytes in the code page given by property 1 |
| 31 (VT_LPWSTR) | A 32-bit count of characters, then UTF-16 |
| 64 (VT_FILETIME) | A FILETIME |
