PathMatchSpec Function
Searches a string using a Microsoft MS-DOS wild card match type.
Syntax
<pre class="clsSyntax">BOOL PathMatchSpec( LPCTSTR <em>pszFileParam</em>, LPCTSTR <em>pszSpec</em> );
Parameters
pszFileParam[in] Pointer to a null-terminated string of maximum length MAX\_PATH that contains the path to be searched.pszSpec[in] Pointer to a null-terminated string of maximum length MAX\_PATH that contains the file type for which to search. For example, to test whether or not pszFileParam is a DOC file, pszSpec should be set to "*.doc".
Return Value
Returns TRUE if the string matches, or FALSE otherwise.

GetCompressedFileSize
The GetCompressedFileSize function retrieves the actual number of bytes of disk storage used to store a specified file. If the file is located on a volume that supports compression and the file is compressed, the value obtained is the compressed size of the specified file. If the file is located on a volume that supports sparse files and the file is a sparse file, the value obtained is the sparse size of the specified file.

);</strong>Parameters
lpFileName[in] Pointer to a null-terminated string that specifies the name of the file.
Do not specify the name of a file on a nonseeking device, such as a pipe or a communications device, as its file size has no meaning.
lpFileSizeHigh[out] Pointer to a variable that receives the high-order DWORD of the compressed file size. The function's return value is the low-order DWORD of the compressed file size.
This parameter can be NULL if the high-order DWORD of the compressed file size is not needed. Files less than 4 gigabytes in size do not need the high-orderDWORD.
Return Values
If the function succeeds, the return value is the low-order DWORD of the actual number of bytes of disk storage used to store the specified file, and iflpFileSizeHigh is non-NULL, the function puts the high-order DWORD of that actual value into theDWORD pointed to by that parameter. This is the compressed file size for compressed files, the actual file size for noncompressed files.
If the function fails, and lpFileSizeHigh is NULL, the return value is INVALID\_FILE\_SIZE. To get extended error information, callGetLastError.
If the return value is INVALID\_FILE\_SIZE and lpFileSizeHigh is non-NULL, an application must callGetLastError to determine whether the function has succeeded (value is NO\_ERROR) or failed (value is other than NO\_ERROR).
