File Sharing is considered one of the best features of Slack. Given that the service is usually used for remote work, having the option to share files with your team makes collaborative work easier and faster to accomplish.  Unfortunately, the feature is not always working on the platform. If you are reading this, we can assume that the app is stuck on processing your file upload.  This is an annoying problem that can get in the way of your workflow.  Most of the time, file upload issues on Slack are caused by server-related problems. However, it can also be due to an outdated version of slack, or your network provider is currently experiencing issues.  Whatever the case is, we’re here to assist you.  Today, we will show you what to do if Slack is stuck on processing your file upload on Windows.  Let’s get started!

1. Check the Servers. 

Being an online service, any feature on Slack relies on the servers to function. If you are experiencing file-sharing problems, it might indicate server outages. Fortunately, Slack has a dedicated page that shows the platform’s status.  If there are reported problems with the servers, the best thing you can do is wait. Sadly, server-related issues can’t be resolved on your end.  On the other hand, you can proceed to the next solution if the servers are fine. 

2. Check Your Internet Connection. 

A slow or unstable internet connection is usually the reason for file upload issues on Slack. If the app is stuck on processing your file, it might be a sign that your internet is running slow or unstable.  To confirm this, run a test on your network using to measure its current upload and download bandwidth.  If the test indicates a problem with your network, the best thing to do before contacting your ISP is to restart your modem or router. This should re-establish the connection with your provider’s servers.  Disconnect your router from the power source and wait for 5 to 10 seconds before plugging it back in.  Once done, perform another speed test to confirm if the restart worked. If the issue persists, get in touch with your ISP and ask them to fix their service. 

3. Check File Size. 

When sharing files on Slack, you need to remember that it should not exceed 1GB. If you need to share a large file or folder with your team, we suggest doing it in batches to avoid issues. Be sure to name the folders in order so that your team won’t have a hard time joining the files back after uploading them.  You can also try compressing it on a .ZIP file and see if you can reduce the file size to less than 1GB. 

4. Update Slack. 

The version of Slack you are using might have an issue related to file upload and sharing. To rule this out, try updating your software to the latest version available and see if the problem goes away.  Here’s what you need to do:  Try uploading your file after the update to see if the problem is fixed. 

5. Clear Your Browsing Data. 

If you are using the web application, we suggest clearing your browsing data before uploading files. Some of your caches and cookies may have gotten corrupted, causing some features to malfunction.  See the steps below to clear your data:  Restart your browser afterward and see if you can now upload your file. 

6. Turn Off VPN. 

Virtual private networks, or VPNs, are third-party services that protect your data from hackers and other entities. They mask your IP address to keep your identity private and redirect your activity to their servers are filter them.  While this process is effective for keeping your data and information safe, it can also cause connectivity issues.  Before uploading files on Slack, make sure that your VPN is turned off.  If your current VPN keeps giving you problems, we suggest checking PureVPN. Unlike other services, it uses high-speed servers to keep your connection fast and reliable while protecting your data.  PureVPN has over 6000 servers worldwide and will work with most streaming services.
