Conisio has performed very well for me over the past four years. I have seen some bad comments about Conisio on this site. My file system has over 300,000 files in it that Conisio manages. During the past four years, Conisio has become a very strong product document management software. Each revision has improve the performance and made it work better with AutoCAD, SolidWorks and all Microsoft products. Just like most PDM products, it has some issues. However, I have run Conisio on several different servers over the past four years and my performance was determined more by my network backbone then the server it’s self. As for some of the comments I have read on the news group about it not handling large files and folders, their most recent version 5.3sp2 resolves many of the slowness issues with regard to folder size and number of files in each folder. In my opinion Conisio is worth looking at because it servers many functions and has a strong market place. Just evaluate it on price, ease of setup and ease of training and I think you will see the value I see. It costs 1/3 of the price of most PDM products and only takes about 3 hours to install (yes, I have done it several times). Also, it takes about 15 minutes to train a new user, because if the user knows windows explorer, they know 90% of Conisio. Of course, this is just my opinion and I have only been using it for four years. Also, I don’t know about you, but when was the last time you spoke directly to the developer and they listened. As a mater of fact I spoke with the CEO of the company last night as I upgraded to version 5.3sp2. He was there to help me when I forgot a step and had to be shown what to do. A satisfied user, Dennis
