How to fix sync issues between local file shares and OneDrive for Business
The Layer2 Cloud Connector runs a Windows Service to migrate, sync
or backup documents between local file server and SharePoint on-prem and online,
OneDrive for Business or Office 365 Groups. It fixes many common sync issues
automatically. Additional tools can be used to be better prepared for the first
"Easy fix" is a Microsoft tool to help in renaming files and folders to prepare
or fix the naming of items in a local folder or OneDrive for Business folder.
To get files to sync successfully,
you may have to rename a wide range and large number of files if their names
contain unsupported characters. This Easy fix tool for Windows automatically
renames files and folders whose current names contain any unsupported
characters. The tool also generates a report of those changes and of any files
that are violating other restrictions that are called out in this article, and
shows which folders were scanned by the tool.
Supported changes by this tool apply only to SharePoint Online. SharePoint
Server 2013 may have a separate set of restrictions that were set by your
The Easy fix tool currently performs the following tasks on the OneDrive
for Business folder or local folder that you specify:
- Removes unsupported characters from file or folder names. For example, a
file that's named This%is%a%test.doc will be renamed Thisisatest.doc.
- If an item has only invalid characters, it will be renamed Invalid Renamed
File. If the item is a folder, it will be renamed Invalid Renamed Folder.
- If a file or a folder is renamed, and the renamed file or folder conflicts
with an existing item on the same directory path, the item will be renamed by
appending an <x> to the name. The <x> placeholder represents is an
integer, starting with the number 1, until all rename actions are completed for
For example, assume that a folder has two files that are named
HelloWorld.doc and Hello%World.doc. Because % is an unsupported character, the
second file is renamed HelloWorld.doc. To avoid duplication in the same folder,
the name of the renamed file will be changed to HelloWorld1.doc.
In addition to file names being changed by this Easy fix tool, several
other rules are run to check for any additional limitations that you may
encounter when it's syncing. A report that documents the issues that were found
is generated and put on your desktop for you to review. A new log file will be
generated every time that you run the Easy fix tool.
