hi, here is an update that should help everyone make autocad run much faster. close any autocad program first. history:
I deleted all shortcut files in the 19 folders in:
c:\user\vern\appdata\roaming\auodesk\Autodesk Mechanical Desktop 2009\r17.2\enu\recent.
I did not delete the folders, just the files in each folder. turns out autodesk saved all of my save as, etc. shortcut files--over 4,000! since day 1. mech. desktop and autocad run faster when opening and saving.
before all this, mech destop took 1-2 seconds to click on a dimension in a layout, before I could move the cursor. now it is instantaneous! I have 4.7 ghz amd64 8 core FX-9590 windows 7 pro 64. always been a fan of amd, intel is ho-hum.
my update for files in c:\user\vern\appdata\roaming\auodesk\Autodesk Mechanical Desktop 2009\r17.2\enu\recent:
Autocad products saves all shortcut files used since day 1 for:
Save Drawing As
Select File
acad-131 (your windows may be different)
New External File
SelectDrawingFileBlkDlg
ButtonEditDlg
there are other folders, but mine were empty.
Also, every time I changed my xref path when opening a drawing file, autocad saved the changed path as a shortcut. in the last 2 years, I changed my drawing file structure a lot, to have more meaning and sense. that means when opening every drawing that references parts, which I changed the name using Windows Exporer, I selected the new drawing name.
Example, I renamed:
Bearing thrust needle 18x31x4 Assy.dwg to Bearing thrust needle 18x31x4 AXK1831 Assy.dwg.
then when opening any drawing file that references it, I select the new file name. after drawing is opened, I then change the reference file definition name to new name, then save my updated drawing.
I'm the only cad user here at Excitron, and I have > 1,000 assembly files referencing parts. shows I have been busy.
so on 11/24/2019, I deleted all files in those folders again, about 1,000 files since 2018.
also did same for c:\user\vern\appdata\roaming\auodesk\Autodesk Mechanical 2009\r17.2\enu\recent, and c:\user\vern\appdata\roaming\auodesk\Autodesk Mechanical 2010\r17.2\enu\recent.
you can look at other installations you may have.
then I took a deep breath,and deleted 79 other individual folders, that contained one new xref path and 1 file in each.
just by deleting these files, MDT2009 runs much faster for all commands. so it seems that any autocad product looks through all these folders for some or all commands. they shortcuts, only 1K or 2K size, but apparently autocad reads them all. And never deletes them. a colossal waste of time, and causing my hard drive to excessively load and search. millions and millions of file operations.
