Regular expressions with Sync feature

Using regular expressions in our Sync feature, you can specify rules in the Folder+ field to include specific folders and file types in the folder. See the 2 tables below for some example scenarios that you can use these expressions:

Sync examples with expressions

Expression Syntax	Folder Path Examples	Use Details
.*	//Production/ExternalFeed/.*	Sync everything under a folder including subfolders
\s	//Bids/Submission\sRequests/.*	Any folders with a space (i.e. /Submission Requests) must be replaced with the \s character
[^/]*\.ext	//CustomerFeed/Reports/[^/]*\.csv	Sync everything under a folder with a specific file type, including subfolders
.*\.ext	//Engineering/.\.csv, //Blueprints/.\.dwg	Sync specific file type in folder, excluding subfolders
.*\.ext$	//folder/subfolder/.*\.csv$	Add $ at end to ensure that the .ext is the very end of the path
function main(syncContext) { if (syncContext.syncTargetInfo.path != null && syncContext.syncTargetInfo.path.indexOf(“/Folder/Path”) != -1) syncContext.syncTargetInfo.path = syncContext.syncTargetInfo.path.replace(“/Folder/Path/”,”/”); }	Please replace the /Folder/Path in the script with the path indicated in your sync rule to remove the replicated folders.	This will prevent the folder path from the Hosted~FTP~ side being replicated on the receiving side and will place the file directly in the target folder without creating the additional folders
