# Uploads and files

> Fixes for uploads, file size and format limits, storage, and downloading files in Review.

## Uploading

<AccordionGroup>
  <Accordion title="My upload is stuck or failed" icon="upload">
    Most often the connection dropped. Open **Upload** in the file table and retry the file, and check your internet connection. Large files are uploaded in parts, so a brief drop only affects the part in flight. If you see **"Upload session not found"**, start the upload again from the beginning.
  </Accordion>

  <Accordion title="'File size exceeds 150GB limit'" icon="file-x">
    The limit is 150 GB per file. Compress the file or split it into smaller parts, then upload again. The 50 GB figure you may have seen applies to ZIP downloads, not to uploads.
  </Accordion>

  <Accordion title="'File extension not allowed'" icon="file-question-mark">
    That format is not on the allowlist. Use a supported video, image or audio format, or write to support if you need one added. See [Compatibility](/en/review/compatibility) for the full list.
  </Accordion>

  <Accordion title="I am out of storage" icon="hard-drive">
    When you reach your plan limit you see **"Storage quota exceeded. Upgrade your plan or delete files to free up space."** or **"File limit exceeded. Upgrade your plan or delete files to free up space."** Delete files you no longer need, or upgrade. If you do not own the account, see [Account and plans](/en/review/troubleshooting/account-and-plans).
  </Accordion>

  <Accordion title="Too many files at once" icon="files">
    You can upload up to 250 files in one go. For bigger sets, upload in smaller batches. If you upload very quickly you may briefly see **"Rate limit exceeded"**, just wait a moment and continue.
  </Accordion>

  <Accordion title="Unable to verify upload limits. Please try again." icon="refresh-cw">
    A short network or server hiccup interrupted the limit check. Wait a moment and start the upload again.
  </Accordion>
</AccordionGroup>

## Downloading and managing files

<AccordionGroup>
  <Accordion title="Nothing happens when I download" icon="download">
    **"No accessible items selected for download"** means nothing in your selection can be downloaded. Pick at least one file or folder you have access to. Folders are included as a ZIP, so you do not have to open them first.
  </Accordion>

  <Accordion title="'Skipped N protected folders. Please unlock them first to download.'" icon="folder-lock">
    Password protected folders are left out of the ZIP. Open each one and enter its password, then start the download again.
  </Accordion>

  <Accordion title="I cannot copy a link" icon="clipboard-x">
    **"Failed to copy link"** or **"Clipboard unavailable"** usually means the page is not on a secure connection. Use the site over HTTPS, or copy the link from your browser address bar.
  </Accordion>

  <Accordion title="'Failed to delete items'" icon="trash-2">
    Check that you have permission, close any open file tabs, then try again. Files in use by an active share can block deletion.
  </Accordion>
