Why am I receiving the “We do not allow upload of the file type that you attempted to upload” error message?

This message indicates that you have tried to upload a file created in a program/software file format that is not recognized by Tk20. Contact Tk20 at to get this file extension added to the Tk20 system files and then try uploading the file again.

Why am I receiving the “You cannot upload file because it would put your disk usage at xxxxxMB, over your disk quota of xMB. Please free up some disk space if you wish to upload” error message?

This message indicates that you are trying to upload a file larger than what your maximum quota allows. Contact your Tk20 system administrator about possibly increasing your disk space.

Why am I receiving the “File you are trying to upload exceeds the maximum size limit of xMB for a file. Try to break this file into smaller chunks and upload them” error message?

This message indicates that you are trying to upload a single file that is larger than the allowed limit. Contact Tk20 at for solutions on how to upload this file.
