Saving turns my file to Read Only - Help

[hillarynan]

Everytime I go to save or do a saveas, my file turns into a Read-Only file type. However, if I close and re-open the file, it is no longer a read-only. But, then when I go to save after a few minutes, it will turn back into read-only. Help!

Ok, not that is should matter, but what O/S?.... what version of AutoCAD?.... is this vanilla AutoCAD or a vertical?.... are the drawings stored on the "C" drive, or a removable HDD, or a flash drive, etc.?.... any other info?

Read Only occurs when one of three things happen:

1.) You don't have permissions to edit the file from that location.
or
2.) The file is already open by someone other than you or in a different session of CAD.
or
3.) When another application is accessing the file but it's not necessarily open in AutoCAD Examples: a "block library" program is allowing you to view a preview image of the file or it is currently being copied from one location to another) .

Technically a virus scanning program could also cause it by not allowing changes to the files in a specific directory.

I know, not exactly an answer, but these are areas to investigate as each situation can be different.

The anti-virus thing would be my suspicion. Be sure to have all autocad files on your "do not check" or low priority list, whether at home or on a network. This includes the .DWG, .DWF, .AC$, .LSP (although lisp routines can have viruses, yet I don't think anti-virus software would know what kind of code to look for. I may be wrong about that), and .bak.
Having said that, we have a viruse here. It alters acad.lsp and acaddoc.lsp to create another file( acadapg) for accounting purposes. like most viruses, it isn't terribly malicious, it just creates a bunch of useless files you have to purge.
