Overview of Dropbox


Produced in 2007, Dropbox is one of the cloud drives that we often use to store files. Offering users free and paid services, generous Dropbox also provides new signups with 2GB of free space. It not only enables syncing files on the Internet through cloud computing, but also stores and shares files and folders. Therefore, even if the computer crashes suddenly, our files will not be lost.

However, many users have encountered some problems when using Dropbox recently. And one of the problems is that Dropbox is not uploading files. So, today, we're going to find out what we should do when the problem of “Dropbox not uploading” happens.

Even though Dropbox supports uploading files by dragging and dropping them in batches, the file size is limited when uploading: up to 300M/file. So, there are times when Dropbox uploads take a long time to complete or even fail to upload, or the file is waiting for an upload prompt.

Then, what should we do to solve such problems? First of all, we need to know what causes Dropbox not uploading files. After that, we can quickly find solutions to solve the problem. Thus, please read the following reasons for Dropbox upload failure carefully, check whether you are encountering similar situations, and then follow the corresponding methods to solve the problem.

Reason for Dropbox Not Uploading

  • Dropbox is not the latest version. If the version of your Dropbox is old, the file cannot be uploaded successfully.
  • The Network connection is not stable. If there is something wrong with the network, Dropbox will fail to upload files.
  • File incompatibility. File names with incompatible characters will prevent Dropbox from uploading the file.
  • File name overlap. Dropbox cannot upload the file if the file name has an overlap with another file on Dropbox.
  • Files are used on other programs. Files being used on other applications will also prevent Dropbox from uploading the files.
  • Dropbox storage reached the cap. When Dropbox space is full, files cannot be uploaded either.
  • Too much cache exists on Dropbox. Too much cache on Dropbox can also cause Dropbox to fail to upload files.

9 Common Ways to Solve Dropbox Not Uploading Issue

After knowing the reasons for files not uploading to Dropbox, you may wonder how to solve the problem. Here are 9 solutions I’ve compiled and I hope they will be helpful.

Solution 1: Restart Dropbox or Your Computer

Dropbox would fail to upload files because of a certain running program stalling. In this case, simply restart Dropbox or your computer can be helpful.

Solution 2: Update Your Dropbox

If the version of your Dropbox is not the latest one, Dropbox cannot upload files successfully either. So, you need to install the newest version of Dropbox.

Solution 4: Check If the Network Connection Is Stable

When you find that Dropbox is unable to upload files, you can stop the uploading process and then check whether the network connection is stable or not.

♦For Wireless Network

  • If you are using wireless Internet, please check the Internet charges and pay for the charges promptly.
  • If the router receives an unstable signal, please restart the router and connect with your computer again.
  • Be sure that the computer is close enough to the router.

♦For Wired Network

  • Check if the contact between the network cable and the computer is poor, then reconnect them.
  • If the network cable is damaged, replace it with a new one.

Solution 5: Upload Compatible File to Dropbox

If the file you upload to Dropbox is a web version that is added directly from other websites, the file will not be uploaded to Dropbox.

Dropbox can store web-based files, but it cannot save files that are added or moved directly from other websites. If you do, the problem of “Dropbox not uploading” will happen. Then how to upload or move web-based files to your Dropbox? Now, you can refer to the following two ways:

►Way 1

Download or export a copy of the file you want to upload to Dropbox. And you should make sure that the file type of that copy is compatible with Dropbox, e.g. .docx. Then upload that copy to Dropbox directly.

►Way 2

Create a Google document, sheet, or slide on Dropbox. Then copy and paste the web-based file into that document, sheet, or slide.

Tip when creating Google Doc on Dropbox:

The email that you sign up for Dropbox account should be the email of your Google account as well. If you create a Google document on Dropbox, it will be automatically saved here and take up Dropbox storage space.

Solution 6: Rename the File

If the file name of a file in Dropbox is the same as the file name of a file you want to upload to Dropbox, the local file cannot be uploaded successfully. So, please rename the file if you encounter this situation.

Solution 7: Close the File on Other Applications

If you see a notification saying that “the file is currently in use, please try again” when uploading a file to Dropbox, you need to close that running program. Before turning off the program, you should be sure that you’ve stored the latest version of that file. Then, you can upload the file to Dropbox again.

Solution 8: Clear Cache on Dropbox

If there is too much cache on Dropbox, it may cause Dropbox not uploading videos, files or images. Here are the detailed steps to clear too much cache on Dropbox on Windows and iOS systems respectively.

The steps to clear Dropbox cache on Windows:

Step 1: Right-click the Windows icon (Win + X) and select Run.
