There is no limit to the amount of files that can be uploaded at once in the file browser.
Users should exercise caution when attempting to upload a large number of files that surpass the browser's processing capacity. During such circumstances, the upload may freeze or fail.
Moreover, only the browser supports specific folders that are being uploaded. If a user wants to upload more than 100 files at once, the operation will be done in 100-file increments.
