Premiere saves weird files in weird folders in werid moments...

I would understand that if that mfx file was the same lenght as the AAF i was trying to export. but it wasn't, the AFF was supposed to be 36 min but the mfx was a video of the last 6 min...?

No idea; perhaps you inadvertantly exported only a portion of the sequence...?

>Plus, to try to export this AFF, I tried to separate the audio for the video and put it in a different sequence and export just that, with no video on the timeline. So how can it export a video...?

Without the actual project and steps you're following, we can't provide meaningful guidance about [above].

>I can't seem to be able to export this AFF, that file is just 3mb and it should be much bigger. I'm quite losing my mind around this...

Unless media is embedded, AAF files don't need to be large. 

> ok, but then why doesn't it delete itself when the export is over?

I have no idea what's clearing out your destination directory.

In my experience, no files delete themselves;  also, PPro does not delete .xmp side car files.

- "finale finale con rendering", with the VLC icon = an .mxf file; the lack of audio was probably the result of your AAF export settings.

I would understand that if that mfx file was the same lenght as the AAF i was trying to export. but it wasn't, the AFF was supposed to be 36 min but the mfx was a video of the last 6 min...? and it's also super big in size. Plus, to try to export this AFF, I tried to separate the audio for the video and put it in a different sequence and export just that, with no video on the timeline. So how can it export a video...?

also I can't seem to be able to export this AFF, that file is just 3mb and it should be much bigger. I'm quite losing my mind around this...

- "finale finale Con rendering.mxf.xmp" = the XMP metadata, associated with the .mxf file. [This was generated because of the metadata export settings in place, when the .mxf was rendered.]

ok, but then why doesn't it delete itself when the export is over?

oh, also premiere didn't work (was crashing because unable to export because it wasn't updated. but when i tried to update it said "update failed") so i disinstalled and reinstalled it again. and this problem is still there

 here you can see the before and after. the file that I tried to export was a AAF file called "for davide". but it also exported these other files. the first one, "finale finale con rendering" si a MXF file bigger than 30gb. my whole project is about 36min in lenght, what that file is is just the last 6 min of the project, and it doesn't have any audio. also the name "finale finale" is the name of one of the sequences.

also the AAF file is just 3mb, not sure if that's how it's supposed to be considering that it's 36min of audio.

... any insight? maybe it's using it as some sort of scratch disk? I have no clue what's going on.

Could you provide all available specifics, about those "files that have odd names, names of sequences or old titles that i gave to previous files that I've exported in the past"???

It would be interesting to get a list of files in your output directory, before and after the export. 

Yes, that is correct. although they do not create themselves just by starting premire, but when i try to export a project. it creates other files that have odd names, names of sequences or old titles that i gave to previous files that I've exported in the past.

Confirming (sorry to sound pedantic, but the behavior you're describing is unprecedented):

• Open /Downloads directory; confirm that there are N items present.
• Launch PPro.
• Open /Downloads directory; confirm that there are now N + X items present, where X is non-zero. 
  
  
  

Do I have that right?

If so...what are the names of the files that magically appear, when PPro is launched?

I would understand if they persist, the odd thing is that they reappear every time i just opne premiere.

and the big files, yes, they have different names, usually the same name of the sequence rather than the project.
