SurDoc Features

Signing up with SurDoc gives you access to 100 GB of free storage space immediately that lasts a year, after which you must either pay for more data or earn free space.

There are multiple ways to earn more free space with SurDoc, such as inviting your friends to create an account, sharing SurDoc information over social media websites, and simply giving out links to your files.

The maximum storage space you can get with this service without paying a penny is 1 TB.


  • Lots of free file storage space
  • Allows sharing folders with other SurDoc users
  • Files can be shared with anyone, even non-users
  • Some shared files can be previewed in a browser before downloading them 
  • Can upload data through a desktop program and mobile app
  • Multiple files can be uploaded at once via a browser
  • Documents and images can be exported as a PDF file
  • Accepts all file types
  • No upload file size limit on documents and media files


    • 100 GB of storage only lasts one year
    • The 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 can only be shared with other registered users. This means everyone you share your files with must also have a SurDoc account.

    This is true with one exception only: files you place in the "My Public Files" folder can be shared with anyone, even public, non-registered users.

    You can also share custom folders you create in your SurDoc account, but you don't get a URL to use for sharing. Instead, you must enter the email address of other SurDoc members that should have access to the folder. You can give members access to edit files in your account or just allow them to download or browse through your files.

    File sharing can also be done through SurDoc's mobile app for Android and iOS users.

    SurDoc Applications

    Download the free SurDoc program for Windows or Mac. SurDoc's desktop application isn't just used to upload your files to your account because it also functions as a free backup program.

    You can setup the software to back up any number of folders from your computer to your SurDoc account. The settings let you define which file extensions should be excluded or included so you're only storing what you want in your SurDoc account. When files are changed, they'll be uploaded to your account automatically.

    You can remove, rename, share, and download your files from the desktop program, but you can't upload files to a certain folder like you can with similar cloud storage services.

    For example, if you back up a "Pictures" folders, it will back up to your SurDoc account under "Pictures." You must then move the images to other folders if you wish to organize them, such as to the "My Public Files" one to share them with non-users.

    SurDoc's mobile website is optimized for mobile use, but there's also a dedicated app for Android and iOS users.

    The mobile app lets you setup automated picture and video uploads to your SurDoc account as well as upload them manually to any of your folders. You can also use the app to copy a file's URL for sharing it with others.

    My Thoughts on SurDoc

    The biggest issue I have with SurDoc is that the free 100 GB of file storage is only valid for one year. After a year's time, you must use the "Renew Free Storage" link from your account to add more storage space, which requires you to do things like invite friends to join SurDoc and share your files with others.

    Something to remember is that after your SurDoc account retires its 100 GB capacity, and before you get more free space using one of the methods above, your existing files will be inaccessible until you add more space to your account. The files will not be removed, but will simply be unreachable for a limited time.

    I like that the SurDoc desktop program lets you limit the upload and download bandwidth settings so you're not clogging up your network when you're transferring files. Some file storage services don't support this feature, which means uploading and downloading files from those accounts oftentimes cause congestion on your local network.

    Another thing I like about SurDoc is that you can sign up with your Facebook, Microsoft, or Yahoo account, which makes creating a new account really simple.
