We usually use email to transfer files, but most email services refuse to accept attachments that exceed a certain size—claiming this helps prevent malicious attacks and reduce risks. Therefore, when sending large files, you cannot rely on this common method. However, there are other equally easy ways to transfer large files. This article will introduce you to three of them.
Method 1: Compress the file before emailing
Email providers often have limits on the size of attachments that can be uploaded. For example, Gmail only allows attachments of 25MB or smaller, and Outlook only allows attachments of 20MB or smaller. To work around this, you can compress the large file to a size that meets the email attachment requirements.
Advantage: Compressing files is the simplest and most direct way to reduce file size to fit attachment limits, allowing you to transfer large files via email directly.
Limitation: File compression typically reduces the file size to only about half of its original size. As a result, this method is only suitable when the file exceeds the size limit by a small margin. Additionally, compressing and decompressing files may lead to data loss or damage. For instance, the quality of videos or images may deteriorate.

Gmail only allows attachments under 25MB
Method 2: Use a cloud drive to transfer files
In addition to sending via email, there are other ways to send large files, such as using Cloud Drive.
Upload large files to a cloud drive (such as Google Drive), then you can send them to the other party by sharing a link.

Advantage: This method ensures better file quality and allows you to send much larger files compared to email attachments. Additionally, the files are saved in the cloud and can be accessed at any time.
Limitation:1. The free storage space on Google Drive is limited to 15GB. Other cloud drives also have similar free storage limits, so you may need to purchase additional storage space if required.
2.Since the file must first be uploaded to the cloud and then downloaded by the recipient, the transfer time depends on your network conditions. This process may take longer than traditional methods.
Method 3: Use DeskIn remote desktop software to transfer files (Most recommended)
Currently, most remote software on the market supports file transfer. DeskIn has enhanced the standard file transfer functionality to provide an even better experience:
1. The free version already supports file transfer with no limit on size and quantity;
2. Fast transmission speed, up to 12MB/s;
3. Ensure your files remain confidential and protected from unauthorized access using 256-bit end-to-end encryption;

5.DeskIn supports seamless file transfer between different devices and operating systems. Whether you are using a Windows PC, Mac or mobile device, DeskIn allows you to easily transfer files across platforms.

There are also security risks when using email to transfer files. Even if you enter just one wrong character, your email may be sent to another person and cannot be withdrawn, which may easily lead to information leakage. While using DeskIn, you need to match the device ID and password, or manual passwordless verification from the other party's computer, which avoids transferring to the wrong object.
