I do the same.  Stick the old ALL file on a thumb drive somewhere for the rare occasion you need to log back to check an old QSO. 73 Herb WB8ASI

Hi Miloš,

sure that file can become large but there's no need to keep all of it in the log files directory. Personally I find it very useful to go back to old QSOs to verify what happened, e.g. when someone wants a confirmation for a QSO that I did not log. I keep all my ALL.TXT entries but archive old entries every couple of years. The ALL.TXT file is just a journal and unlike the wsjtx_log.adi file it is not used by WSJT-X.

Hi Bill,

And what about the ALL.TXT file? In my case it is about 100x larger than wsjtx_log.adi.

WSJT-X only appends entries to its log files when you click "Ok" in the "Log QSO" window. I have no idea why anyone would think that having all ones completed QSOs in the same log file is an issue, storage requirements are tiny at less than a 1000 bytes per logged QSO. That's more than 1,000 QSOs logged per megabyte and more than a million (1,000,000) QSOs per gigabyte.

For me, probably, for some no...  A lot of people run their drives almost full. No clue why these days, storage is cheap!

I had a friend that did this, and after 6 months of FT8 operations he had "issues", with no disk space...

We all know not to fill the HD, but some do anyway...  While I have GBs of space left today, I might not tomorrow.  All things that write to disk in the fashion WSJT-X does, ought to have limits placed on them...

What if WSJT-X goes rogue, and starts filling that file...  Limits if properly implemented will help in that case, they might even help track the issue, if the alert the operator to the issue.

you ever get to operating system limits, you will be a super hero in the Ham

I have always wondered if this file grows in size forever?  Are there any
limits on it?

Anyone have any idea about how many entries the WSJT-x log file can
take before it starts affecting performance? I’m thinking that at some
point it might be good to start deleting the oldest entries. For
example, you could delete entries older than 4 years. That would mean
that stations you haven’t worked in 4 years would again show up as new
stations. It might not be a bad thing to work someone again after 4
years, especially on VHF.
