Troubleshooting File Upload Errors in EZ File Drop

If you received a message saying that files could not be uploaded to your connected cloud storage destination, this article will help you understand what went wrong and how to fix it.

What Happened?

When someone uploads files using your EZ File Drop form, those files are temporarily cached in our secure, encrypted server while we attempt to deliver them to your connected cloud storage service (like Dropbox, Google Drive, or OneDrive).

In some circumstances, the transfer to your cloud storage service can fail. The good news: the files are safely cached and will remain available for 30 days, giving you time to fix the issue and retry the upload.

Common Causes and How to Fix Them

1. Insufficient Storage Space

If your cloud storage account has reached its limit, it won’t accept new uploads—even if everything else is working correctly.

How to check:

  • Sign in to your cloud storage provider (e.g., Google Drive, Dropbox, OneDrive, Box).
  • Confirm you have enough available storage for the file(s) that were uploaded.

If you're out of space:
You’ll need to free up space or upgrade your storage plan before retrying the upload.

2. Folder Permission Errors

EZ File Drop may no longer have permission to the folder you selected as your upload destination. This can happen if:

  • The folder was deleted, renamed, or moved.
  • Sharing settings were changed (by your or someone else), removing EZ File Drop's access.
  • Your cloud storage account was disconnected or its permissions were reset (this can happen automatically after password changes or policy updates).

How to fix it:

  1. Log in to your cloud storage provider (e.g., Google Drive, Dropbox, OneDrive, or Box).
  2. Locate the folder you originally selected as this form’s upload destination.
    • If the folder has been deleted, moved, or renamed, you’ll need to either restore it or choose a new destination folder in EZ File Drop
  3. Confirm that EZ File Drop still has access to that folder.
  4. If needed, reauthorize your cloud storage connection in EZ File Drop and reselect the correct upload folder.

How to Retry the Upload

Once you’ve confirmed the upload destination still exists, there’s enough storage, and the permissions are correct, here’s how to manually retry the upload:

  1. Log in to EZ File Drop.
  2. Click View Submissions for the affected upload form.
  3. Find the submission with the error and click More Info.
  4. Click Retry Upload.

If everything is set up correctly, EZ File Drop will attempt the transfer again immediately.

Less Common Issues

In some less common situations, file uploads can fail due to other causes. Here’s what else to check:

IT Admin or Enterprise Account Restrictions

If you're using a cloud storage account managed by your company, your IT team may have updated policies that restrict third-party apps (like EZ File Drop).

What to do:
Check with your IT administrator to confirm that EZ File Drop still has access and that nothing has changed in your permissions or folder access rights.

File Name Too Long

Some cloud storage services reject files with long names—especially if dynamic file naming is enabled in your EZ File Drop settings.

What to do:

  • Check if any uploaded file names (including any automatic prefixes) exceed 260 characters.
  • If so, ask the original uploader to rename the file(s) and re-upload using a shorter name.
