FILE SHARING GUIDE
How to Share a Folder Online
When you need to send dozens of related photos, videos, documents, or project files, sharing them individually can become messy. A folder transfer keeps related files together and gives the recipient one place to access them.
Why share a folder instead of separate files?
Imagine sending 40 event photos, a group of work documents, or several video clips. Uploading and sharing each item separately could leave the recipient with dozens of different messages or download links.
Keeping related files together makes the transfer easier to organize. The sender manages one transfer, and the recipient knows the files belong to the same collection.
Common reasons to share a folder
• A collection of vacation or event photos
• Video clips from the same project
• Client documents and supporting files
• Design assets and exported files
• School or work project materials
• Forms, PDFs, spreadsheets, and presentations
How folder sharing works
A browser-based file-sharing service can let you select the contents of a folder and prepare them as one transfer. Instead of emailing the files directly, the service uploads the selected content and creates a share link.
The basic process:
1. Choose the folder you want to send.
2. Let the service prepare and upload its contents.
3. Wait until the transfer is complete.
4. Copy the generated share link.
5. Send that link to the recipient.
Check the folder before uploading
Before selecting a folder, take a moment to look through what is inside it. It is easy to accidentally include an old draft, an unrelated screenshot, a duplicate video, or another file you did not intend to share.
Cleaning up the folder first can also reduce the total upload size and make the transfer easier for the recipient to understand.
Folder size matters
A folder containing hundreds of high-resolution photos or several long videos may be much larger than it appears. Before starting the transfer, check the approximate folder size so you know whether it fits within the service's current upload limits.
Larger transfers can also take more time. Upload speed is affected by your internet connection, the total amount of data being sent, the device you are using, and the number and size of the files inside the folder.
Keep the page open during the transfer
Browser-based transfers depend on the page remaining active while files are being prepared and uploaded. Closing the tab, refreshing the page, losing your connection, or allowing a mobile browser to suspend the page can interrupt an unfinished transfer.
For a large folder, it is best to keep the device connected to a reliable network and leave the transfer page open until you receive confirmation that the upload has completed.
Desktop and mobile folder selection can differ
Folder selection is controlled partly by the browser and operating system. Desktop browsers generally provide more complete folder-selection controls, while some mobile browsers may show the files inside a folder rather than letting you select the folder itself.
If your phone does not offer the folder-selection option you expect, using a desktop or laptop can provide a more predictable experience for large multi-file transfers.
Should you create a ZIP file yourself?
A ZIP file combines multiple items into one file. This can be useful when the folder structure itself matters or when the recipient expects to download everything together.
You do not always need to create a ZIP manually. A file-sharing service may handle the folder as part of the transfer. If you do create a ZIP yourself, remember that photos and videos often do not become dramatically smaller because those formats are already compressed.
Protect folders containing private files
Anyone who receives an active unprotected share link may be able to access the transfer. That means you should consider the contents of the entire folder before sharing it.
If password protection is available, it can add another step before somebody can access the files. For private transfers, consider sending the password separately from the share link.

Temporary file sharing is intended for delivery rather than permanent storage. JustSeconds guest links are designed to expire after 7 days. Registered users can choose longer expiration periods, up to 30 days where available.
Make sure everyone who needs the folder has enough time to download it before the link expires.

How to share a folder with JustSeconds
On supported browsers, choose the folder option from the JustSeconds upload area and select the folder you want to send. JustSeconds prepares the selected content and creates one temporary transfer.
Once the transfer is complete, you receive a shareable link and QR code. Send the link to the recipient instead of sending each file individually.

Can I send a folder without emailing every file?
Yes. A file-sharing service can create one transfer link for the selected folder contents, so you can send the link instead of attaching every file individually.
Why can't I select a folder on my phone?
Mobile browsers and file pickers do not all support folder selection in the same way. Some devices may let you browse the files inside a folder but not select the folder itself.
Does putting photos into a ZIP make them much smaller?
Usually not by much. Formats such as JPEG photos and common video formats already use compression, so ZIP files are often more useful for packaging them together than for dramatically reducing their size.
Does the recipient need an account?
A recipient can normally open an active JustSeconds share link without registering. Password-protected transfers also require the password chosen by the sender.
