extension in the input field and click a radio button to select the type of check
(No CRC, Fast CRC, Full CRC, Macro Fast CRC, Macro Full CRC) you want to
use for it.
NOTE:
The “?” wildcard may be used in user-defined extensions. For
example, by specifying OV?, AVP Inspector for Web Servers™ will test files
with extensions of OVL, OVR etc.
The type of check specified in the “CRC check for selected extension”
field is as follows:
• No CRC check: no CRC check is performed on files with this
extension. Only the file size, time and date of creation is saved to the
table.
• Fast CRC check: the check is dependent on the internal structure of the
executable file. It combines reliable file validity control with minimal
calculation time. This type of check is strongly recommended for COM,
EXE, VXD, DLL, 386, CPL, SCR and other executable files.
• Full CRC check: a CRC is calculated based on the contents of the
entire file. This type of check provides the most complete control over
file validity, but requires a much greater calculation time. It is
recommended for BAT and SYS files.
• Macro Fast CRC check: this check is dependent on the internal
structure of the document file (such as Microsoft Word
®
, Microsoft
Excel
®
and Microsoft Access
®
documents) and allows reliable file
validity control for OLE2 documents. It is recommended for files with
DOC, DOT (DO?), XLS, XLA, (XL?) and MDB extensions.
• Macro Full CRC check: a CRC is calculated on all of the macros
contained within a document file. This type of check provides the most
complete file validity control for OLE2 documents.
NOTE: Macro CRC checks are recommended only for OLE2 format files
that may contain macros. So far the following applications are supported:
Microsoft Word
®
, Microsoft Excel
®
and Microsoft Access
®
.
