 QualCoder is designed to be used as client-based software to be used by one person at a time. (A second coder can use the same project on the same computer, or the project folder can be transferred to the second coder's computer). QualCoder is not designed to be multi-accessed at the same time. Accessing the project in a cloud location is not recommended, it may corrupt the database if a database connection is lost during any database updating processes.
