Using a WFP TM in WFC
The translation memory (TM) format used by Wordfast Classic is a tab-delimited text file whereas the TM format used by Wordfast Pro 5 is a SOLR database. If you want to use a Wordfast Pro 5 TM with Wordfast Classic, you need to export the TM as a TMX file (e.g. TM.tmx), then import it with Wordfast Classic using the Select TM button. Upon importing the TM.tmx file, Wordfast Classic will copy the content of the TM.tmx file into a newly created tab-delimited text file called TM.txt and select it as your active TM.
Tags
While using a Wordfast Pro TM in Wordfast Classic, you can get better matching rates (sometimes raised from 70s to 100) by opening (a copy of) the WFP TM in Word and applying one find-replace operation on the tags before using the TM in WFC.
WFP TM format tags look like this:
&tA; &tB; &tC; &tD; ect.
They start with (&t) and end with (;). So, one can use MS Word Find-Replace dialogue to replace them using this (four-letter) formula:
Find what: &t*; Replace with: (Leave it empty!) Use wildcards (checked)
Currently, you can do the same using the Wordfast Classic filter "Remove All Tags".
Open Data Editor by clicking the second rightmost toolbar button, and then open the "Tools" tab.
In WF Classic, do not forget to (1) "Reorganize" the TM, and (2) lower the "Fuzzy Threshold" to 50.
