Most CAD programs such as AutoCad have a history of recently opened files. In AutoCad go to TOOLS/ OPTIONS/ FILES/ Automatic Save location. There you should find a file with the same name but a different file extension such as .BAK (AutoCad back-up) You can set AutoCad to automatically save to any time period, such as every 15 minutes.

Make a copy of this .BAK file so you keep that unchanged, Then change the file extension of the copied .BAK file to .DWG. Then you should be able to open this file. A file with an extension containing the $ symbol needs to be recovered using the programs recovery tool, in FILE/ DRAWING UTILITES/ RECOVER

If you're using a different CAD program look for this backup file wherever the programs Autosave files are set to be stored.

One other possiblity is the file extesnsion is set by your computer to open with another program for some reason. Right click and hit "open with"

    It's also possible that whoever sent it back to you saved it to a newer version that your older program can't open. If you are using AutoCad go to Autodesk and download TrueView. It will allow you to view and save back to a previous version.

How to unlock password protected auto cad files.


it appears that autodesk2_bing.gif did infact pull the command to unlock drawings from the newer apps. but the way to get around it is to find a file of the same name, only with a .dwk or .dwl extension, and then delete it. then when you open the drawing, it will run the recover command and fix it up for you to view and edit again

My Inkjet 2800 won't print DWG. (CAD) files. I have no problem with other files; word, excel, photos ... When I try a CAD file, the printer shows "printer error."


Does the printer show you Printer error with number and letters following it? Prior to printing, check the 'print preview' to see how the layout of the printing is showing. If the CAD drawing is not adjusted to fit on the paper in the printer, you may from time to time get a printer error.

My Acer Aspire One crashes when the battery gets to around 50%. Is this a fault with the battery or the machine?


is it xp or linux? i believe there's a problem with xp versions to do with wireless, been testing it, it won't start if wireless is turned on, crashes at the windows loading screen. If you disable it in safe mode, restart it, it will start. but when you go into windows, and enable wireless, it crashes straight away. hope someone has the same problem and a fix is found soon, for now i'll try to convince shop to exchange or refund it
