Some files are corrupted when multiple large files are downloaded

[rsmaior]

I've downloaded almost 850 files inside a complex folder structure of more than 60 directories. Most files are big GeoTiff images. Many files have a size of 2 GiB (generally the maximum for GeoTiff).

I had no problem with most files. But with some 30 images I had problems. They were smaller and corrupt compared to the original from Google Drive. I think for some reason the download process is interrupted for some files and does not continue correctly, thus stepping into another set of files to download and leaving the interrupted download as is.

Unfortunately, I can't share the folder, since it could cause copyright issues.

Not asking to make a complex checksum system for each files, but maybe it would be easy to do a simple size comparison. Simply list the size of the origin file and the downloaded file, if the downloaded is smaller, than the process of downloading it should continue or restart from zero.
