Description |
Matches most valid ArcCatalog FeatureClass catalog paths. Rejects most invalid paths. Accepts mapped drive letters and UNC network paths. UNC Server names must begin with a letter and may only include letters and numbers. Will not accept directories that include ".gdb", ".mdb", ".sde", or ".mdf" in their name. Otherwise accepts mid-string spaces and "."s (dots) in directory names. Will not accept special characters in FeatureDataset or BaseName. Will not accept FeatureDatasets or BaseNames that begin with a number. Limits total path length to 160 characters. Accepts file, personal, sde, and SQL GDBs, as well as shapefiles. Shapefiles have the ".shp" extension and cannot appear in geodatabases. Accepts GDB Feature Datasets. Identifies <Workspace>, <Root>, <Drive>, <Server>, <DirectoryTree>, <Directory>, <Geodatabase>, <GDBName>, <Extension>, <FeatureDataset>, and <BaseName> as sub-strings.
