When I run CheckDisk on a Windows 8 Consumer Preview volume, I get:
> chkdsk /v S: The type of the file system is NTFS. Volume label is Windows 8. WARNING! F parameter not specified. Running CHKDSK in read-only mode. CHKDSK is verifying files (stage 1 of 3)... 91392 file records processed. File verification completed. 28 large file records processed. 0 bad file records processed. 20224 EA records processed. <------------------ huh??
Why are there so many extended attributes on the volume? I thought no one used EAs anymore...
As an example, the file
\Windows\CSC\v2.0.6 has an extended attribute that contains the string
Ԡ 1X C8A05BC0-3FA8-49E9-8148-61EE14A67687.CSC.DATABASE P X Չ: Չ: ˌΦ]cᑡPcďŠ 4 C8A05BC0-3FA8-49E9-8148-61EE14A67687.CSC.DATABASEEX1 P X _, N0t 08 C8A05BC0-3FA8-49E9-8148-61EE14A67687.CSC.EPOCHEA 8 ͌Φ]cᑡPcďŠ }
which (thanks to an answer below) seems to be related to client-side caching of offline files.
However, it seems like most other EAs are different -- e.g. the file
\Program Files\WindowsApps \Microsoft.BingFinance_1.0.1022.0_x64__8wekyb3d8bbwe\pages\ETF\js\ETF.js
and most other files contains (mostly) the string
$KERNEL.PURGE.APPXFICACHE, which doesn't seem to be related. What might this be for?
