Not gonna lie, @mikeappsreviewer nailed some classic options (browser drag-and-drop, Google Drive for Desktop, CloudMounter magic), but I still find all of those a little… meh for giant uploads. Browser works-ish for a handful, sure, but the minute I dump a full vacation folder (think 800 RAW photos) the whole thing just cries and sometimes refuses to tell me what it ACTUALLY finished uploading. If you get the “1 file at a time” vibe, try holding Ctrl or Shift when selecting in the upload dialog—sometimes browsers just hide the multitool capabilities behind bad UI.
Here’s what Google doesn’t advertise enough: zipped folders. Yup: slap those files into a .zip or .rar, upload a single chunky boi, then unzip inside Drive with a web app like ZIP Extractor. Less risk of stalled files mid-upload, and you only monitor one progress bar. Sure, you’ll need an extra step in the web interface, but it’s a life-saver if your connection drops.
Honestly, I’m not super into dedicated desktop drive sync tools since they can eat up disk space and trigger versioning nightmares. But if you want Drive to feel like a mounted folder, CloudMounter (like @mikeappsreviewer mentioned) is slick, and I haven’t had it corrupt big transfers like some others (side-eyes Backup & Sync). Third-party tools aside, don’t be afraid to experiment—sometimes the “jank” hack (zipping) cuts through the nonsense faster than Google’s own workflow.
Biggest tip: test with a small batch first. Murphy’s Law loves a big batch upload.
TL;DR: Try zipping, use Ctrl/Shift for multi-select in browser, and yeah, CloudMounter if you want no-fuss drag-and-drop. Avoid Google’s own sync for huge batches (imo), unless you live dangerously.
