Export of large chats not possible via GUI buttons #95

Open ModischFabrications opened 4 years ago

ModischFabrications commented 4 years ago

Related to #32, which does not seem "resolved" to me.

I have the same problem that exporting a selected chat does not work:

  1. Select small chat (500 msg), press .txt -> exportDialog, everything working
  2. Select huge chat (51.000 msg), [loading time ~20s], press .txt -> nothing happens, CPU stays idle, waiting >20min still won't show anything

Other export formats behave the same. I can't share the files due to the private nature of these chats but it seems like the problem stems not in the file but the size.

OS: Win10 Professional

I have no clue what you are trying to tell me, linking to it again has not given me any more to think about...

I'll try to reproduce that.

Right now I just exported a chat with 191 000 messages. It would crash if I just clicked any export option as soon as possible, but I gave the program some time to try and load the chat first. I believe it was some 15 or 20 minutes, I was doing other things. Anyway, all 3 export options worked fine and within some 10s.

Hi, I'm currently having the same problem. A chat with over 120'000 messages will take a long time to load in the GUI and if the export chat is clicked, the program crashes. Will try @fabiorfreitas approach of waiting as long as it takes for the chat to appear before exporting.

Is there any cmd option to export without GUI? Thanks

@jmribeiro YSK that I ended up resorting to a similar app on the Play Store, BackupTextForWhatsapp. It's not the same, but it worked for my purposes.
