<![CDATA[Downloading from Mega creates a copy of the file in filesystem.]]>So I noticed that when I download a file from Mega, it creates a copy of the file in that path:

C:\Users\K4TTO\AppData\Roaming\Opera Software\Opera GX Stable\File System\000\p\00
Making Opera GX folder to take more space than it should because the download actually goes to "my downloads" too. (Is like donwloading the file Twice)

Maybe related to my previous post:

My thought is that the issue with GX as it's not clearing the temporary file (the twin file) once it is transferred to your Downloads folder.

I wonder if anything can be done to autodelete those "twin" files. Like an extension or even integrated support in Opera GX

At least those that support the File System API.

So I think the problem is related with MEGA and Opera GX?

If the twin is created exclusively in this combination, but not using Opera Desktop or Chrome, this would also be my conclusion (provided that the behavior of Opera GX is not affected by an add-on in this respect).

Downloaded all your files none created a twin, then donwloaded 1GB from MEGA and it created a twin

So is that the situation?

  • If you download my 1 GB test file with Opera GX, Opera Desktop and Chrome from my online storage provider, none of these browsers will create a twin file.
  • If you download my 1 GB test file with Opera GX, Opera Desktop and Chrome from MEGA, only Opera GX will store this twin file

Tested another MEGA download of 1GB and it created a twin in the same path

Two years ago I came across this MEGA FAQ article when I was interested in online storage providers:

Are there any file size limits on MEGA?
We do not impose any artificial limitations on file size other than your available Cloud Drive space. While all current browsers are capable of uploading large files, downloading is size-constrained by Internet Explorer, Firefox and Safari due to their lack of support for HTML5 streaming file writing. Google Chrome and Opera can handle large files, but they require plenty of free disk space on your system boot volume.
We recommend for you to use MEGAsync to download large files.

I don't know if this statement is still valid today (this article was last updated in August 2016), or if other online storage providers also utilize HTML5 streaming for their download feature, or if this situation is MEGA-specific.

So I provide here four large files, for download from another cloud provider than MEGA, to check,

  • whether in these cases Opera GX also creates these twin files
  • how other web browsers behave.

No password is required for the download. The files have no file extension, no usable content and were created with FileTool. If I no longer see any download activity, I will delete them at some point.
