If you ever gotten that corrupt message, to contact the sales or a message that files can't be found. Having your backup/recovery settings set right could save you hours of remodeling.
System Options Backup/Recover.
When I get started with SolidWorks after getting the system settings for the company, this is one of the first places I go to set the folders to backup and auto recover to the local hard drive. I also turn off the remove backups older than # of days. In the past I have opened files that others have modeled that did not have these settings set, and have been able to recover files that they lost.
Some of the reasons files get lost have been that they were not saved in the right place and IT was cleaning up the servers and just deleted anything that looked like trash because it was not located where it should have been. A user accidently deleted a file that they have spent months working on. Or the file has become corrupt and can't be opened because of interruption in the connection between the server and the computer. If all the options to get the file have been exhausted the backup is my go to. If all else fails then it is time to contact IT to see if they would be able to recover the file for you. In my experience it has been a long wait, from hours to days for them to be able to find the file and then the file that they restore may be older than what I keep in the backup folder.
After a few years or months depending on the hard drive you may want to go thru and delete some of the older files or the more standard ones. Nuts, bolts, fittings, before getting rid of projects. When the hard drive does start to fill up programs will start giving you some problems.
Another example where this has saved me lots of time is when Opening an assembly that I worked on months ago to check a problem that production was having. For some reason the file blew up and all the parts were scattered all over the sheet and assembly. A simple close and look for the old backup file could save the day.
