ProjectWise BulkLoad tool crashes trying to upload a folder structure (lots of sub folders and documents) right after you try to proceed to the next step after selecting folder to import.
After investigations it appeared that the BulkLoad tool failed to load documents that had the path+file name length longer than 255 characters (this might happen when creating a folder structure in non Windows environment, like for example Linux).
To identify all paths that might be too long please use the following:
To be able to import these documents it is required to shorten the documents that has too long path. Most likely Windows will not allow modifying these paths, so it would be required to modify them in the system that was used to create this folder structure (like Linux).
