Important note on Btrieve files:
The files are manipulated in the Temporal folder. Due to a limitation on the BUTIL.EXE utility for Btrieve, the Temporal folder may have problems to be recognized by the utility, and produce false errors. If that is the case, pick up a folder closer to the root or shorter in name. For example, a folder like "temporal" may not work, but a folder "temp" may do instead (under the same folder tree).
