No disk space in ticks generating function / Excessive use of RAM and disk storage

Computer specs: RAM 32gb / NVME M.2 500gb / CPU Ryzen 9 5900x

Hello, when starting the optimization in the strategy tester with 10 years of backtesting and 2 years of forward, starting from 01/01/2008, only allow the optimization with the major pairs. Since in the minor pairs, in addition to using all the ram and m.2 disk (as it also does in the majors), it does not directly start to optimize, and this is because the m.2 disk of 500gb is full, which is crazy that during optimization more than 300gb of data is written to the m.2 storage disk. Apparently it fills the entire disk with large temporary files and on each processor agent (thread). In addition, the downloading of histories of other currency pairs that are not those corresponding to the optimization begins. There I attach images of how the m.2 storage disk is before starting the optimization and how it fills up after starting the optimization in some of the minor pairs, also of the images of the downloading of histories of other pairs that are not the ones that are currently being updated.

I ask the question here because I already looked in the forum and this question is unanswered, I already tried to uninstall and reinstall the mt5 platform and it does not work either, also consult with a fellow programmer of this platform and he tells me that the same thing happens. I would like you to give me a solution to be able to optimize the minor pairs with my EA, and also an answer about why it saves so much data in cache and in temporary files, which causes the saturation of the storage of all my storage disks, in addition the saturation of all RAM (32GB) causing the collapse of the computer.

I await your response and I attach the images of what happened. Thanks.

    Hello friend, you just have too much data downloaded for backtesting, i recomend to just download the data for one pair, backtest, optimize or do whatever needs to be done and then delete the downloaded data, it is ussualy stored in a hidden folder C:/users/(your name)/appdata(this one is hidden)/Roamming/Metaquotes/Terminal


    In this folder you should find some folders with tons of numbers and letters for a name, usualy in the first one, but try all of then if not, you'll see a folder called tester/history, you will find a surprise there in the form of lots of GB in data...
