Question

“Due to lack of space” is displayed and the file cannot be uploaded.

Answer

From the settings menu, open Limitation > Disk Limitation, select the space that cannot be uploaded (e.g.: Collabo Space) from the pull-down menu on the upper left, and check if the upper limit is set in the “Use the upper limit size” item.
Then, confirm the current storage amount with the gauge below.

For example, suppose you have set the maximum size to 70GB.
On the other hand, if the current storage amount is 60GB, the size that can be uploaded is 10GB remaining, so if you try to upload a file of a larger size, it will be displayed as “Due to lack of space”.
