Flags Registry Subkey (Compact 2013)

3/26/2014

You can verify registry settings by looking at the Common.reg file. For more information about the contents of registry files, see Registry File. For more information about the names of some registry files, see Run-Time Image Configuration Files.

The following table shows registry flags that are set using the Flags name in the registry. To set them, set the Flags name in the registry to a combination of these values using the bitwise OR (|) operator. They are deprecated in Windows Embedded Compact 2013: they are not commonly used but are still defined in the source code and will have an effect if set in the registry. For replacement flags and settings, see the descriptions in the following table. For more information about the replacement flags, see Registry Settings for FATFS Flag Values. For more information about the location of entries in the registry, see FAT File System Registry Settings.
