Cache directory, Files tab, Settings Dialog Box (Error Detection)

Displays the directory where Purify stores instrumented files. Type the path and name of the directory you want to use to cache instrumented files, or click images\brbut.gif to search for a path and name.

Purify caches instrumented versions of files used by a native-compiled (unmanaged) program to avoid reinstrumentation for subsequent runs of the same program. Purify checks the cache directory each time you run the program and reinstruments new or updated files. For previously cached files, Purify uses the timestamp and instrumentation level to determine whether the file needs to be reinstrumented. If you change the instrumentation level, Purify automatically deletes the cached version and reinstruments the file the next time you run the program. Generally, it is not recommended that you delete an instrumented debug file (.pdb, .map, or .dbg); Purify reinstruments debug data files only when the associated module is reinstrumented.
