# File Size Mismatches

When adding or removing flash memory to the Catalyst, there will be a file size mismatch when attempting to connect Alarmware™ with the Catalyst. When adding flash memory, Alarmware™ will detect this situation and handle it automatically. In situations where Alarmware™ has a bigger file size than the Catalyst, a message will appear, instructing you to reduce the file system size by the calculated number of bytes. Clearing user-recorded messages and log file data can reduce file size.
