Thanks Dave.  What I don't understand though is this: in WSJT-X Settings/colours there is a 'Rescan ADIF Log' box but how does it know the location of the log and how do I know it is actually being scanned?  I might well be barking up the wrong tree but nothing appears to happen when I try this.  Log4OM (and no doubt any other similar logging program) updates and saves an .adi file and I assume that is what WSJT-X should be using to determine whether a station/country has been worked before?  However what I don't know is how I can ensure WSJT-X is actually 'seeing' this file!  I note too that WSJt-X creates a file (c:/Users/Administrator/AppData/Local/WSJT-X) called ALL.TXT  It is huge (90MB) and seems to show all stations logged going back about a year.  I'm not at all clear which of these files is used as a reference.  Any ideas?

Hi Jeff,

WSJT-X keeps it's own local log file, it is in ADIF format. That log is used for WSJT-X to highlight needed DXCCs, gridsquares, zones etc.. It can be confusing when using third-party applications like JTAlert or DX Lab Suite SpotCollector which can also highlight parts of decoded messages to help you pick the most productive QSO partners. In general WSJT-X highlights whole decode lines whereas third-party applications highlight individual words in decodes, usually wanted callsigns. When you click the button in WSJT-X "Settings->Colours" to rescan the ADIF log file it is this log file that is rescanned, you might do that if you have substituted an ADIF export from another log keeping application that has details of more QSOs than those recorded directly by WSJT-X.

The ALL.TXT file, WSJT-X stores alongside it's other log files, is a journal of all decodes and transmissions. It is not a QSO log file although it can sometimes be very useful when reconstructing or verifying past QSOs. The file can be big but it is not searched by WSJT-X, only appended to, so its size does not directly affect performance. I strongly recommend keeping all ALL.TXT information, possibly indefinitely as queries about historic QSOs do occur, sometimes years after they happened. You might consider archiving the ALL.TXT file every year or so if you are concerned about the disk space used.

I am concerned that your WSJT-X installation appears to be under your PC's Administrator account, that implied that you logged in as Administrator to install WSJT-X, or worse still you are using an Administrator account for routine day-to-day PC operation. This is bad practice and leaves you wide open to many nasty malware exploitations.
