Is the Boxifier app displaying symbols that are unknown to you? This is what they mean:
|The folder with the blue arrows suggests that the folder is currently syncing. Be patient and wait until this symbol becomes green, as shown below.
|This symbol is our favorite one and we think it is your favorite one, too. It shows that all the files in this folder are synced and up to date.
|When you see this symbol, please wait while getting more information. Boxifier is checking the content of the folder to see if there were made any updates since the last check.
|In case you see this symbol on a boxified folder, please contact our support team at email@example.com. There might be a problem, but we’ll solve it ASAP.
|This symbol appears when a folder is unchecked in the Selective Sync settings in Dropbox, so please check this folder in the Selective Sync to start syncing it.
This symbol reveals that the folder is not syncing because it cannot be accessed. This can happen if the drive or network share that folder is stored on is not accessible (either not present or not connected).
This could also be because the original folder was moved or renamed, and the files cannot be updated. Check this article, in order to relink a previously synced folder.
