Android application package of AIDA64 version 1.31, 7.75 MB, with a Chinese tag meaning it works on TV devices.

Anonymous 1 MB BIOS binary with only a generic file name, so the source device, brand and board number are unknown.

Zip archive, 734 MB, labelled as Microsoft Office 2007; the name does not indicate edition, language or whether a licence key is included.

Archive for the HP Compaq NX9000 notebook, roughly 1008 KB in RAR format. The name provides only the model, without board number, revision or a list of contents, so open…

ZIP archive of 345 KB named BoardViewR4, most likely a release of a boardview viewer program rather than a board layout, given the version-like R4 suffix.

Compact 57.1 KB ZIP archive named BoardView2, likely an early version of a boardview viewer; the name carries no brand, board or version details beyond the number 2.
