IDS_MERGE_COMPRESSING_ERROR
Error compressing the combined index file.
Given when HxMerge.exe encounters an internal error during the compression stage of the merge operation.
To correct this error
Check to see if there is an existing full-text index (.HxQ) file with the same name as the output file specified in the HxMerge project (.HxM) file. If there is one, move it to a different directory, or delete it if it is no longer needed. If there is a duplicate .HxQ file and it is read-only, HxMerge cannot overwrite it.
Ensure that there is enough free memory on the local computer.
Ensure that you have the correct permissions to write files on the local computer.
