How to Send a 100 GB File to a Client
Send a 100 GB file without shrinking it. Compare transfer limits, calculate upload time, and use a client handoff checklist before sharing the link.
To send a 100 GB file, choose a service that accepts the whole file, upload the original, and share a download link. Check the recipient's collection window before you start: at a sustained 100 Mbps upload speed, the upload alone takes at least 2 hours, 13 minutes, and 20 seconds.
RainFiles Drizzle has a 250 GB storage allowance for $5/month, so a 100 GB delivery fits when enough space is free. The options below include other paid services. For a one-off job, first check whether storage you already pay for can handle it.
A 100 GB delivery requires a paid RainFiles plan. Free includes 1 GB for signed-in users. You can use it to test a small delivery before upgrading; no card is required to create the account.
1. Check the limit for one delivery
The following paid options advertise allowances that accommodate a 100 GB delivery. This is a limits comparison checked in October 2026, rather than a speed ranking.
| Option | Relevant advertised allowance | Suitable when |
|---|---|---|
| RainFiles Drizzle | 250 GB storage; files fit within available space | You want repeat client deliveries for $5/month |
| Smash Pro | Unrestricted paid transfer size | The client collects within its retention window |
| TransferNow Premium | 250 GB per transfer | You want a longer collection window |
| Filemail Pro | 250 GB per transfer | You want ongoing availability |
| MASV On-Demand | Usage-based delivery | Project-specific outbound charges suit the job |

SwissTransfer's free limit is 50 GB, so a single 100 GB file does not fit. A 100 GB folder could be divided into smaller packages if that is practical for the client, but splitting creates extra collection steps. SwissTransfer limits.
Do not assume that a smaller subscription works because the provider also advertises a larger business plan. Check the exact tier you are buying.
2. Estimate the upload time
Upload speed is often lower than download speed. Use the upload result from your connection test, rather than the largest number in your broadband advertisement.
For a decimal 100 GB file, the theoretical minimum is:
seconds = 100 × 1,000,000,000 × 8 ÷ upload bits per second
| Sustained upload speed | Theoretical minimum for 100 GB |
|---|---|
| 20 Mbps | 11 hours, 6 minutes, 40 seconds |
| 100 Mbps | 2 hours, 13 minutes, 20 seconds |
| 1 Gbps | 13 minutes, 20 seconds |
Real delivery takes longer because of overhead, congestion, processing, and interruptions. A file shown as 100 GiB contains more bytes than 100 GB, so it also needs more time at the same speed. Allow a buffer before the client deadline.
3. Prepare a package the recipient can use
Give the file a clear project name and version. If you are delivering a folder, preserve its structure and include a short contents list. Remove unrelated working files before uploading.
A ZIP archive can keep a folder together, but already-compressed video may shrink very little. A large archive may also require room for both the downloaded archive and the extracted contents. Tell the client approximately how much space to reserve.
Keep your source copy. The delivery link is a handoff mechanism, and the client may not collect it immediately.
4. Make the upload resilient
Use a stable connection, connect the computer to power, and avoid sleep during transfer. If interrupted uploads are likely, select a tool with documented resume support and test that behavior before the deadline.
Keep the browser or desktop application open until the service confirms completion. A selected file, a progress bar, and a usable recipient link are different stages. Wait for the final one.
With RainFiles, a 100 GB delivery fits within Drizzle's 250 GB allowance when you have enough free space. Choose a link lifetime of up to 15 days, or use Downpour for 1 TB shared storage and links without scheduled expiry while your subscription is active and the files remain stored.
5. Test access and communicate the collection window
Open the link in a signed-out session or ask an external colleague to test it. Confirm the file name, size, password behavior if used, and the collection deadline. For sensitive files, use access controls suited to the job and share a password separately.
Send a concise handoff message:
Your final project package is ready: [delivery link]. It contains one 100 GB file. Please download it by [date and time zone] and confirm that it opens. The password will follow separately. Let me know before the deadline if you need a different collection arrangement.
The recipient's connection needs time too. Uploading by the deadline does not guarantee they can collect the whole package before a link expires.
For a video handoff, follow the guide to preserving original quality. If clients need lasting access, compare links without scheduled expiry.
Common questions about sending 100 GB
Can I send a 100 GB file for free?
The free SwissTransfer offer cited here accepts up to 50 GB, and RainFiles Free has 1 GB of storage. Neither fits one 100 GB file. A service you already subscribe to may handle it without an additional purchase. Splitting a file is another option, but the recipient needs every part and a way to reconstruct it.
Will ZIP make a 100 GB video small enough?
Usually not by much if the video is already compressed. Use ZIP to keep related files together; choose a transfer allowance that fits the resulting package. If the recipient needs both the archive and its extracted contents, they may need roughly twice the package size in free disk space.
What if the upload stops halfway through?
Check whether the selected service and upload method can resume that upload before committing to a deadline. A generous file-size allowance does not establish resume support. Keep the original locally and test a representative package first.
