You may have used an incompatible character in the files or folder name(s). Check to see if any of the following characters are used in a file or folder name and rename them if so:

• / (forward slash)
• \ (backslash)
• < (less than)
• > (greater than)
• : (colon)
• " (double quote)
• | (vertical bar or pipe)
• ? (question mark)
• * (asterisk)
• Dot at the end of the file name (.)

Also note, that the following file types are ignored by the SecureSafe Client meaning they will not be synced to your SecureSafe:

• Name starts or ends with space or tab
• Empty files (with size 0 bytes)
• File and folder names with more than 128 characters
• desktop.ini
• thumbs.db
• Thumbs.db
• .ds_store
• .thumbnails
• Temporary Items
• .trashes
• .DS_Store
• .Document Revision-V100
• .fseventd
• .apdisk
• .svn
• .htaccess
• .securesafe.*
• .*conflicted copy.

Furthermore, if you exceed the storage limit for your SecureSafe, all files you add to your local SecureSafe folder after this point will not be uploaded to your safe.
