Reading the Conversion.log file
You should open and read the Conversion.log file after converting one or multiple files. It lists the conversion status and possible problems found during conversion, such as fields with invalid names.
The log file is created in the same folder as your converted files. If you used the multi-file conversion method to convert more than one file at a time, the Conversion.log file contains information for all the converted files.
In most cases, you can correct problems in converted files. If the log file indicates a problem that would be complicated and time-consuming to fix after conversion, you may want to try correcting the problem in the original file using a previous version of FileMaker Pro, and then convert the file again.
