18. File Type Restriction Directives
File type restriction directives may be specified in CVDL files.
- When specified outside of a VDL, these directives have VDL file scope and apply only for VDL rules which appear following the directive in the same VDL file.
- When specified as part of a VDL, the directives apply only for that particular VDL.
- The file type restrictions apply only if VFind is reading SmartScan input from UAD, which reports the file types.
The directives and their meanings are:
<"...",...> specifies a list of file types to scan, i.e. scan only the file types specified. <!"...",...> specifies a list of file types to not scan, i.e. scan everything except for the file types specified. <> resets to scan everything.
If the SmartScan file type reported by UAD is "unknown", or if VFind is run standalone (without SmartScan input), then all VDL file type restrictions are ignored and everything is scanned.
