Article completeness

I expanded this article a bit and took off the stub since pretty much all the information needed is there.

What about the format that it uses? Or what it scales the picture to? What is the process of encoding this file? In general, it could be helpful to be more technical. — Preceding unsigned comment added by 69.129.55.57 (talk) 18:08, 8 July 2007 (UTC)[reply]

Having just checked on a screengrab, it's 96x96 (or 94x94 for what you see, as the images are given a 1-pixel border on display, however it would be strange to save them to a size not a multiple of 8), or for folder thumbnails, the first four images in the folder at 40x40 (with a 1-pixel divider, so 81x81 overall)... or of course, for non-square images, 96 on the longest edge and the shorter one sized proportionally. I'll put in a simpler version of this on the article. 77.102.101.220 (talk) 00:42, 21 July 2008 (UTC)[reply]

File format

I thought these were CFBF files saved by OLE IStorage, but looking at the header for Vista ones with a hex editor it doesn't seem to match the magic number. -- bitplane 18:26, 8 July 2009 (UTC)[reply]

Vista Thumbacaches are in an entirely new format. It's a simple indexing system in which the index points to the 4 secondary files which contain the actual thumbnail images. They use a mixture of hashes of the thumbnail, image and a ThumbnailID mixing the MFT Record Number, Date and Drive GUID. I know the entire format and can work with it from personal knowledge so this is all unsourcable. - Jimmi Hugh (talk) 01:22, 9 July 2009 (UTC)[reply]

"preventing system wide use of the data"

What does that mean??? —Preceding unsigned comment added by 203.206.162.148 (talk) 04:38, 7 August 2009 (UTC)[reply]

Well, it means (but is incorrect) that thumbnail data cannot be used in other parts of the system, aside from those related to the actual image. What it is should, and is trying, to say is that the thumbnail image data cannot be accessed arbitarily by any program, because the files are fragmented around the file system. - Jimmi Hugh (talk) 08:44, 7 August 2009 (UTC)[reply]
