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
