# File sharing for game developers

Builds are big, change often and must not leak. Testers and journalists each need their own copy, and you need to know which copy went where.

**Quick answer:** Game builds run from a few hundred MB for mobile to tens of GB for PC. Upload a zipped build to Share Large Video Files (up to 20 GB), require an NDA before download, give each tester or journalist a personal link so a leak can be traced to one link, limit downloads per person, and send a checksum so testers know the build is complete.

## Files game developers send, and how big they get

| File | Format | Typical size |
| --- | --- | --- |
| Android build | APK, AAB | 100 MB to 2 GB |
| PC build, zipped | ZIP, 7z | 1 to 50 GB |
| Engine project with assets | Unity or Unreal project folder | tens to hundreds of GB |
| Texture source files | PSD, EXR, TGA | 50 to 500 MB each |
| Press kit (trailer, screenshots, logos) | MP4, PNG, ZIP | 500 MB to 5 GB |
| Crash dumps and logs from testers | DMP, TXT, ZIP | 1 MB to 2 GB |

## Can it go by email or chat?

Can you send a 5 GB zipped PC build (about 5 GB) as an attachment?

| App | Limit | Fits? |
| --- | --- | --- |
| Gmail | 25 MB per email | No, send a link |
| Outlook.com | 20 to 25 MB per email | No, send a link |
| WhatsApp (document) | 2 GB per file | No, send a link |
| Telegram | 2 GB per file | No, send a link |
| Facebook Messenger | 100 MB per file | No, send a link |
| Discord (free) | 20 MB per file | No, send a link |
| Slack | 1 GB per file | No, send a link |
| WeTransfer (free) | 3 GB per transfer | No, send a link |
| **Share Large Video Files** | 20 GB per transfer | Send the link anywhere |

Limits from our [file size limits by app](https://sharelargefilesfree.com/file-size-limits-by-app) table, checked against each service's help pages.

## A workflow that works

1. Zip the build (7z or ZIP) and make a SHA-256 checksum with the file hash checker.
2. [Upload](https://sharelargefilesfree.com/) it and tick **Require an NDA before download** with your playtest or embargo agreement.
3. Set **Download limits: per person** to 1 or 2 and **Who can open the link** to confirmed emails.
4. On your Transfers page, create a **personal link** for each tester or outlet; switch the main link off so only personal links work.
5. Collect crash dumps and recordings from testers with a **Request files** link.

## Recommended options

| Option (under More options) | Setting | Why |
| --- | --- | --- |
| Require an NDA before download | On (playtests, embargoes) | A signed record from every tester |
| Personal links (Transfers page) | One per tester or outlet, main link off | A leaked link points to one person; revoke it alone |
| Download limits: per person | 1 or 2 | No spare copies to pass around |
| Where and on how many devices: Countries | Your test regions | Keeps a regional test regional |
| Available from | Embargo time (press kits) | Assets open when the embargo lifts |
| Expires after | Until the next build | Old builds disappear |

Set these once, press **Save current** next to **Preset**, and reuse the same options for every build with one tap.

## Builds over the transfer limit

If a zipped build is over 20 GB, split it into parts with 7-Zip or the split file tool and send the parts in one or more transfers; testers join them and compare the checksum. Do not re-compress already-compressed assets: pak files, video and audio barely shrink, so a ZIP mainly keeps the folder together.

## Frequently asked questions

### How do I send a playtest build safely?

Require an NDA, use confirmed emails, limit downloads per person, and give each tester a personal link so you know which copy went where.

### Can I tell which tester leaked a build?

Personal links record opens and downloads per link, so a link found online points to one recipient. Switch it off without affecting the others.

### How do testers know the download is complete?

Send the SHA-256 checksum with the link; they compare it with the file hash checker after downloading.

### Can I release a press kit at the embargo time?

Yes. Set Available from to the embargo; before then the link shows a countdown.
