I want to upload attachments, but the available file names are not in pdf or rar format. This post was last edited by laiqi on 2009-3-30 21:11 ]
two reasons: First: You have not yet reached the level to be able to upload, so you are temporarily unable to upload. It is recommended that you participate in more technical exchanges and get ratings to improve your level! second: This is a technical exchange area. It seems that this kind of information cannot be uploaded. If you want to upload such information, it is recommended that you upload it in the two sub-sections of "Engineering Project Management Data Sharing Area" and "Engineering Project Management Irregular Data Storage Area". Thank you for your participation and cooperation!
