greedy86 Posted October 31, 2011 Posted October 31, 2011 Hi all, Emm....wee question for you here. Sadly, on Friday....my computer crashed whilst i was working...and when i re-opened my AutoCAD and selected the drawing from the Recovery Manager. BUt.....the problem is i think i may have opened the wrong file. However...i went to the autosaves for my cad files aswell....and it wasn't in there either. Is there anyway i can get my work back...? Or....will i have to start from scratch? Thanks Quote
ReMark Posted October 31, 2011 Posted October 31, 2011 You opened the wrong file? How? Did you save the drawing under two different names? As quoted from the DotSoft website. In AutoCAD, other than the DWG file, there are other files you are working with, whether you know it or not. BAK files: Unless you turn it off in OPTIONS, when you save a drawing that already exists on file, the .DWG is renamed to .BAK, then the new data is written to .DWG. Don't rely on this for true safety of your files, because .BAK files have been known to become corrupt. AC$ Files: These are temporary files created by AutoCAD during the process of creating the drawing. They are only of value to AutoCAD during editing and are usually cleaned up when AutoCAD closes. These files are useless if AutoCAD crashes. SV$ Files: These are autosave files, controlled by the setting inthe OPTIONS dialog. These files are the equivalent of a DWG, you would only need to rename them if AutoCAD crashes. It's important to note that if AutoCAD closes normally, these files are deleted! Quote
BIGAL Posted November 2, 2011 Posted November 2, 2011 Nice answer Remark if your real desperate you can undelete files but you need to do this pretty quick after a crash situation it requires "undelete" software search web etc. The other thing set your autosave time a bit shorter we run 15mins this realisticaly = about 1 hr. The other thing is always continously save rather than only at end of day. An explanation a deleted file is not actually deleted off the disk it only has its file space set to be free to be written to. Quote
ReMark Posted November 2, 2011 Posted November 2, 2011 (edited) Back in the days of DOS there was the UNDELETE command. Norton Utilities also had its own version of UNDELETE. BIGAL: You are right about a file not actually being physically erased from a hard drive. The sectors are marked as "available" thus meaning data can be written to that area of the hard drive. That's one of the reasons people were warned not to save any files to disk after accidentally deleting a file they wanted to try to retrieve. They were advised to try to recover the file in some fashion using the UNDELETE command or a similar utility. The newest tool for recovering a deleted file is called Pirifrom Recuva. It was a recommended "freebie" talked about in the May 2011 issue of Pc World under "Storage Essentials". Find it at... find.pcworld.com/71661 Edited November 2, 2011 by ReMark Quote
BIGAL Posted November 3, 2011 Posted November 3, 2011 Just a bit more a good idea, I was asked to help an architect as his brand new Pc had died after 2 weeks as I lived around the corner the pc had a tape backup unit in it. Anyway short answer PC is dead did you do a backup of your work ? answer No. they lost a considerable amount of time= money to get back to the same spot. The omen always backup to an affordable point. Quote
