It worked but the creation dates don't seem to be attributed with the files.
Uhm, weird. Last time I checked all the files inside the .zip were in chronological order according the date. Probably the developers have modified some attribute recently for the compilation of the compressed file to download.
Well, but at least you have a backup of 1104 of your posts in .txt format in your PC right now. ;)
And as for if you also want recover the original 'markdown' or HTML code of all those 1104 posts, I can help you out with that too. But that will cost you at least a generous tip in SBDs or Steem Hahahaha. };)
Just click here and introduce each one of the links of your posts that you want to recover in the format indicated in the website. Yeah, it might be a sluggish process one by one. But at least you'll have first the ones you like the most. And in a short time and little by little you could get all of them if you dedicate yourself to it.
Cheers!! :)
