I found Dockit product through SharePoint.com and found it extremely useful. We used Dockit to import hundreds of documents into SPS. Users were in desperate need for them but refused to take the time to upload them. Dockit saved us the upload time, and more importantly, made the information available in a timely fashion. Small issues were worked out quickly by a capable and dedicated customer support staff.
We find that Dockit is an extremely valuable tool for migrating intranet content to SharePoint Portal Server. When you are faced a large number of documents to migrate each of which has to be populated with metadata, Dockit reduces considerably the effort involved in publishing information. Typically it reduces the time a user has to spend per document by 75%, by enabling documents to be published in batch mode rather than real time through the standard SPS interface.
The Dockit application proved extremely useful for importing large numbers of files and folders quickly and easily into SharePoint. Previously, we were having to import files individually, but through using Dockit we were able to deal with huge directories in a fraction of the time that it would have taken. An excellent tool, really glad we found it.
We used Dockit to import over a thousand engineering documents, preserving the folder structure. It was simple to use and saved us a lot of time.
