the SV%-file, which is the automatic saved file (by default after every 10 minutes). The BAK-file, which is the last prior version of the DWG-file, created in the same folder as the DWG-file. Open the file as you would any other drawing file.In Windows Explorer, locate the backup file identified by the.When a program is about to overwrite an existing file (for example, when the user saves the document they are working on), the program may first make a copy of the existing file, with. bak” is a filename extension commonly used to signify a backup copy of a file. Restore from a BAK file (see To Restore a Drawing From a Backup File | AutoCAD).Browse to and select the file in question. Open a new, blank drawing then type RECOVER at the command line.dwl2 files if they are found next to the. If you try to delete them while a user has the file open, you will not be allowed to. Sometimes, especially when AutoCAD crashes unexpectedly, the DWL and/or the DWL2 files will remain, which could prevent users from opening the files. These files will be erased when closing the drawing unless the drawing is unexpectedly closed by crash error. What are DWL and DWL2 files?ĭWL and DWL2 files are temporary hidden files that AutoCAD creates for an open DWG file by WHOHAS. FYI Windows Notepad can open DWL files is that’s all you want to do. If the save cannot occur promptly enough, in the interests of NOT losing data, Autodesk products will save to the SAVnnnn.tmp or SAVEnnnn.tmp file.And in addition to Ronald’s information instead of opening the DWL-files with notepad, you can also use the command WHOHAS in AutoCAD to select any drawing and see if it’s locked and by whom. I read somewhere in the Autodesk knowledgebase that AutoCAD &/or Civil &/or Revit will lock a file (or cause the OS or NetOS to lock a file) in the event that timing issues occur during a Save. (In some rare cases, the File > Properties > Details does not show an Owner.)
Ours do not seem to be removed by routine garbage collection: Here's a sanitized current list without project or drawing names: Then, it appears, THEY have to be updated to point to their newly renamed xREFs. One problem that ripples out from this is if the file in question that cannot be saved is xREF'd by other files.
In many cases it does not crash the program or the system, but simply prevents saving except under a new name, and the folders on our server are littered with SAVnnnn.tmp files, *.ds$ files, and the.
We have a similar problem to the AutoCAD 2018 issue in the topic line, except with Civil 3D 2017.
