What Was SurDoc? SurDoc was a free online storage service that started every new user off with 100 GB of storage, enough space to keep thousands of photos and music. MEGA is similar in that it offers a whopping 50 GB. File sharing was also supported with SurDoc and your account came with free software for your computer and smartphone. Most cloud storage websites offer these features, too, such as Dropbox. SurDoc Features Signing up with SurDoc gave you access to 100 GB of free storage space immediately that would last one year, after which you had to either pay for more data or earn free space. The maximum storage space you could get with this service without paying a penny was 1 TB. If you miss the 1 TB you were getting with SurDoc, and if you're fine using a Chinese website, 360 Security Cloud will net you a huge 10 TB of storage without the one-year limit. Most cloud storage services let you get more free space at no charge if you invite your friends to join, download their software, etc. This was how SurDoc was and is also how MediaFire works—get 10 GB at the start and work your way up to 50 GB for free. Here are some other features SurDoc supported: Pros: Lots of free file storage spaceAllows sharing folders with other SurDoc usersFiles can be shared with anyone, even non-usersSome shared files can be previewed in a browser before downloading them Can upload data through a desktop program and mobile appMultiple files can be uploaded at once via a browserDocuments and images can be exported as a PDF fileAccepts all file typesNo upload file size limit on documents and media files Cons: 100 GB of storage only lasts one yearThe file size of executables and compressed files can't exceed 10 MB for a single upload File Sharing With SurDoc All files in every folder could only be shared with other registered users. This means everyone you shared your files with had to also have a SurDoc account. This was true with one exception only: files you placed in the "My Public Files" folder could be shared with anyone, even public, non-registered users. This is a lot like how Dropbox works. Others like MediaFire's FileDrop feature and pCloud's public folder, let others send files to your cloud storage account by simply uploading them to the folder of your choice—very handy if you're going to put the files in your account anyway. With SurDoc, you could also share custom folders you created in your SurDoc account, but you didn't get a URL to use for sharing. Instead, you had to enter the email address of other SurDoc members that should have access to the folder. You could give members access to edit files in your account or just allow them to download or browse through your files. Like nearly every other free cloud storage service, file sharing with SurDoc could also be done through their mobile app for Android and iOS users.
