Hello,
I suggest to separate the downloads for the portable version like the setup version and not put everything in one .zip
In my case i need the 32 bit version, extracted is 36,4 MB. Why i need to download 61,8 MB so the double of the size  since i don't need linux or the 64 bit?
Thanks

I can clearly see that the implication is "You never know what you might need with portable version". Many software developers do this with portable editions. CPU-Z, HWiNFO, and Process Explorer are only some examples. And I believe this is good unless you are running portable version as your daily driver on a stationary basis.

Technically all you need is the EXE and "tixati_portable_mode.txt"
If you pop into the channels there are people who have the links for current (and older) versions of Tixati.
