How to Send Large Files for Free and Key Considerations! Tips for Safe File Sharing

Why Can't Large Files Be Sent via Email?

Have you ever experienced an "attachment size exceeded" error when trying to send video files, high-resolution photos, or heavy presentation materials for work or private use? Generally, the upper limit for email attachments is around 20MB to 25MB. To send files larger than this, you need to use methods other than email, namely file transfer services or cloud storage.

In recent years, with improvements in smartphone camera performance and other advancements, the size of data we handle daily has grown significantly. Knowing how to send large files smoothly and for free has become an essential skill in modern digital life.

Main Methods for Sending Large Files for Free

There are two main free methods for sending large files:

• FreeのFile Transferサービス：ブラウザからUpload fileし、発行されたURLを相手にSendだけのシンプルな方法です。FS!QRもこれに該当します。手軽さが最大の魅力です。
• cloud storageのShare機能：GoogleドライブやDropboxなどのFree枠を利用し、特定のファイルやフォルダのShareリンクを発行する方法です。ファイルを長期Saveしたい場合に向いています。

Important Considerations When Using Free File Transfer Services

Although free file transfer services are easy and convenient to use, there are several key points you must keep in mind to ensure safety.

Security and Privacy

Make sure to check whether uploaded files are stored encrypted and whether there is any risk of being snooped on by third parties. When sending files containing confidential or personal information, choosing a service with password protection is an absolute rule.

Retention Period and Auto-Deletion

Free transfer services are designed to automatically delete files after a certain period of time (from a few days to a few weeks). It is important to clearly communicate the download deadline to the recipient. Additionally, choosing a service where data is reliably erased on the system side helps reduce the risk of information leaks.

Ads and Clarity of the Download Option

Some free services display large amounts of ads on screen, making it difficult to find the correct download button. To avoid stressing the recipient, choosing a service with a simple, intuitive interface is another tip for smooth file sharing.
