You have just completed a new promotional video, made the finishing touches on the e-book, or completed the first draft of the PowerPoint presentation. However, when you try to email the file to the team, you receive a message stating that the file is too large. Sending large files via email can be challenging and frustrating. Gmail limits the file size to 25 MB, which means that many photo and video files-even large documents containing a lot of images-are not suitable. Many other email platforms have the same or similar file size limits, but even basic files can surprisingly quickly exceed the 25 MB limit. If you need to upload and send large files, you may need a little creativity, but there are many solutions to help you. Create ZIP file You can compress large files into ZIP files to limit the space they occupy. It is not difficult to create a compressed file, it only takes a few seconds. Keep in mind that the recipient will need to know how to unzip the file to access the document. This file compression method is useful for documents, but not for already compressed JPEG or MP3 files. File compression software can compress all files in a folder with one operation, thus saving time and effort. It is suitable for Windows, Mac, and Linux operating systems. Use cloud storage Cloud storage services such as Google Drive can store large files and let you share them with others. Google Drive allows you to add files to folders and then share those individual files or entire folders with others. You can also create a download link and grant others permission to view or edit the file by selecting permissions. With a Dropbox subscription, you can send large files, including video files and a large number of graphic files. Dropbox allows any recipient to view and download files, so you don't have to worry about the operating system, device compatibility, or whether you want to send to an iPhone or Android phone. With Dropbox, you can upload files and create shareable links to email to all recipients. Dropbox Spaces also enables you to share complete projects of large files. This is ideal when you are working with customers or partners and need to share multiple large documents. Both Dropbox Space and Dropbox Spaces allow you to control the actions that recipients can perform, including restricting comments, downloads, and editing. If you need a higher level of security, you can also use password protection. Use Raysync Raysync also provides a solution for sending large files. You can use Raysync to create a file upload form on your website. You can then change the upload size limit for a single file to a maximum of 1 GB. Raysync also allows you to set the maximum number of files that will be accepted for each submission, thereby helping to ensure a smooth upload process for users. It is best to limit each submission to 25 files. If you allow multiple files to be uploaded, the size of each file is limited to 100 MB. After you create a file upload form on your website, you can easily share the link with anyone who needs to upload a file to the form. Don't worry about uploading restrictions on email file size or using third-party programs. Register for file sharing service If you often need to send large files, please consider signing up for a free file sharing service, such as Securely Send. Secure Send is easy to use and can send files up to 2 GB. You can safely upload and share files directly through the website, and you can even password-protect your email and request a read receipt to ensure that the file arrives safely. You can send up to three emails per month without registering an account. You can also register for a basic plan, standard plan, or advanced plan. The basic plan allows you to send up to 20 messages per month, with a file size limit of 1 GB. Upgrade to the standard plan, you can get 50 messages per month, and the maximum file size is 2 GB. Correct file transfer options The correct way to send large files depends in part on the type of file you are using and the method you are most used to. Tech-savvy teams can easily create ZIP files or use file sharing and storage programs . However, if you need to receive documents from other people, Raysync can simplify the process so they don't have to worry about any additional steps. These solutions have their uses. The most important thing you need to consider is to find the right option.

As a solution provider for large file transmission, Raysync has a self-developed ultra-high-speed transmission protocol, which can easily meet the extremely fast transmission requirements of TB-level large files and massive small files, and provide professional large file transmission and transmission management services for major enterprises. What designs have been made for file storage in Raysync? What storage methods does Raysync support at present? Today we give answers to these two questions. Let's first clarify the three concepts of object storage, file storage, and block storage: Object storage: A strategy of managing and manipulating data storage as different units . These objects are stored in a separate warehouse and are not affected by files in other folders. Get each piece of data and designate it as an object. The data is stored in a separate warehouse, instead of a file in a folder, and is bound with the associated metadata and unique identifier to form a storage pool. File storage: Data is stored as a piece of information in a folder to help organize data among other data. This is also called layered storage, which imitates the storage mode of paper documents. When you need to access data, your computer system needs to know the path to find data. Block storage: Split a file into individual data blocks, and then store these blocks as separate data. Each piece of data has a different address, so there is no need to store them in a file structure. Among the above three storages, object storage adds comprehensive metadata to files, eliminates the hierarchical file structure used in file storage, and places all contents in a flat address space called a storage pool. Object storage has no archive hierarchy, and the source data is completely customizable, so compared with file or block storage, the restrictions are much less and the resources are optimized; At the same time, data can be added forever, and unlimited scalability greatly reduces the storage cost of data; Faster data retrieval and better data analysis promote the wide application of object storage. The use case of the object storage: Providing rich media: Define workflow by using industry-leading solutions to manage unstructured data. Reduce the cost of rich media distributed globally. Managing distributed content: Optimizing the value of data throughout its life cycle and providing competitive storage services. Embrace the Internet of Things : Effectively manage machine-to-machine data, support artificial intelligence and analysis, and reduce the cost and time of the design process. Storage methods supported by Raysync: As an enterprise-level large file transmission software, Raysync has provided high-performance, safe, and stable large file transmission and transmission management services for 2W+ enterprises in IT, finance, film and television, biological genes, manufacturing, and many other fields. As shown in the above table, Raysync has a powerful file storage function, supports more than ten mainstream object storage services, and can meet the diverse storage needs of enterprises.

The increase of data is the inevitable development of science and technology, and the big data brought by the progress of the times is both an opportunity and a challenge. For the problem of slow transmission of big files, we should think: Is the big data itself or the improper way to deal with the data the root cause of enterprises falling into the dilemma of big data? 1. The challenges brought by big data to file transfer 1) Large Amount of Data How big is the amount of data? Now, the files basically start at GB level, and TB and PB files can be said to be the most frequently encountered file transmission units in the office of medium and large enterprises. 2) Low Transfer Efficiency The amount of data increases, the existing network bandwidth is limited, and the network is congested. If we encounter the situation of weak network, long-distance, trans-provincial and trans-national, the transmission speed of large files is simply terrible, and the trans-national transmission of 10GB files may take several tens of hours. 3) High Risk Network security threats have caused the cost of data leakage to soar. Exposure of sensitive data in the process of data transmission and enterprise interaction; The cloud storage associated with file transfer status and the operation of office workers all have potential risks of data leakage. 2. The Solutions 1) Improve the work efficiency via a large file transfer tool Professional file transfer tool software has perfect countermeasures on packet loss, latency, and transmission efficiency of large file transfer, which can greatly improve work efficiency.
