Path variables allow you to specify values that get replaced during upload.
You may use path variables in the folderPath and fileName fields of your uploads, but not in the filePath field, since this is interpreted literally.
Name of the file on the uploader's device (excludes the file extension).
File extension of the file on the uploader's device (includes the leading "." character).
The current date (UTC).
The current time (UTC).
The current time (UTC) encoded as base-58. Always 8 digits in length. Value increases over time.
The current time (UTC) inverted and encoded as base-58. Always 8 digits in length. Value decreases over time. Useful for sorting files by time descending (if used at the start of the file name).
The current year (UTC).
The current month (UTC).
The current day (UTC).
The current hour in a 24-hour format (UTC).
The current minute (UTC).
The current second (UTC).
The current millisecond (UTC).
Unique numbers and letters (base-58).
If this variable is present and a unique path cannot be determined, the file upload will return an error.
Replace X with a value from 1 to 20.
