SuperFetch, is a memory management scheme that enhances the least-recently accessed approach with historical information and proactive memory management. [http://technet.microsoft.com/en-us/magazine/2007.03.vistakernel.aspx]
Providers of scheduled training courses should be listed in alphabetical order, and should be listed in only one section. Non-Commercial training is typically offered by governmental agencies or organizations that directly support law enforcement. Tool Vendor training is training offered directly by a specific tool vendor, which may apply broadly, but generally is oriented to the vendor's specific tool (or tool suite). Commercial Training is training offered by commercial companies which may or may not be oriented to a specific tool/tool suite, but is offered by a company other than a tool vendor.

SuperFetch, is a memory management scheme that enhances the least-recently accessed approach with historical information and proactive memory management. [1]

Note that the following format specification are incomplete.

SuperFetch DB files

The Ag*.db files are of the SuperFetch file format. E.g.

AgAppLaunch.db
AgCx_SC*.db
AgGlFaultHistory.db
AgGlFgAppHistory.db
AgGlGlobalHistory.db
AgGlUAD_%SID%.db
AgGlUAD_P_%SID%.db
AgRobust.db

The SuperFetch DB files can be stored in uncompressed or compressed form, where different version of Windows use different compressed forms:

  • Compressed SuperFetch DB - MEMO file format; Windows Vista
  • Compressed SuperFetch DB - MEM0 file format; Windows 7
  • Compressed SuperFetch DB - MAM file format; Windows 8

Compressed SuperFetch DB - MEMO file format

The MEM file consists of:

  • file header
  • compressed blocks

This format uses the LZNT1 compression method

File header

The file header is 84 bytes of size and consists of:

Offset Size Value Description
0 4 "MEMO" (0x4d, 0x45, 0x4d, 0x4f) Signature
4 4 Uncompressed (total) data size

Compressed blocks

The compressed block size is the chunk data size, which is part of the LZNT1 compressed data, + 2 bytes for the size of the chunk header itself.

The uncompressed block size is 4096 (0x1000) or the remaining uncompressed data size for the last block.

Compressed SuperFetch DB - MEM0 file format

The MEM file consists of:

  • file header
  • compressed blocks

This format uses the LZXPRESS Huffman compression method

File header

The file header is 84 bytes of size and consists of:

Offset Size Value Description
0 4 "MEM0" (0x4d, 0x45, 0x4d, 0x30) Signature
4 4 Uncompressed (total) data size

Compressed blocks

The file header is followed by compressed blocks:

Offset Size Value Description
0 4 Compressed data size
4 ... Compressed data

The uncompressed block size is 65536 (0x10000) or the remaining uncompressed data size for the last block.

Compressed SuperFetch DB - MAM file format

The MAM file consists of:

  • file header
  • compressed blocks

This format uses the TODO compression method

File header

TODO

Offset Size Value Description
0 4 "MAM\x84" (0x4d, 0x41, 0x4d, 0x84) Signature

Compressed blocks

TODO

Uncompressed SuperFetch DB format

TODO

File header

TODO

Offset Size Value Description
0 4 0x0000000e Unknown (Database type or signature?)
4 4 Uncompressed (total) data size

TRX files

The Ag*.db.trx files are of the TRX file format. E.g.

AgCx_SC*.db.trx

Note that the following format specification is incomplete.

File header

The file header is variable of size and consists of:

Offset Size Value Description
0 4 1 Unknown (Version?)
4 4 Unknown
8 4 File size
12 4 Maximum number of records (of the record offsets array)
16 4 Number of records
20 ... Record offsets array, where the record offset is a 32-bit integer. Unused record offset are set to 0.
