Read File Path
ReadFilePath is a sandbox setting in Sandboxie Ini. It specifies path patterns for which Sandboxie will not apply sandboxing for files, and will not allow writing.
. . . [DefaultBox] ReadFilePath=C:\WINDOWS
This example forces the C:\WINDOWS folder, and everything below it, to be readable, but not writable (or deletable) by sandboxed programs.
Note: ReadFilePath is a restricted form of OpenFilePath. As with OpenFilePath, any already-existing sandboxed contents for the specified file or folder locations, are ignored.
