# Known issues and limitations

* When uploading more than 1000 files at once, it may take some time for the user's web browser to generate a list of files to be uploaded. The web browser may appear to be frozen/stuck during this file listing. This is more a limitation of web browsers than our file browser.
* When using the drag and drop feature to upload files from the local machine, the upload will start automatically (although not instantly), but the "Upload" button is still displayed in an active state. If the user drags and drops files, and then immediately clicks the upload button, the files will be uploaded twice, resulting in upload errors for some or all files. This issue will be addressed in a future release. For now, as a workaround, do not click the upload button if dragging and dropping files. Note that if the files are being uploaded using the file picker (instead of dragging and dropping), this issue does not apply.
* Empty folders cannot be uploaded. This is a web browser limitation since the web browser can only expose a list of files and their paths, not the full filesystem structure. Folders are inferred from their paths, but if a folder is empty, it will not be present in the list and therefore will not be uploaded/created in the platform. A workaround may be to create an empty file inside the local folder that needs to be created.
