new parts dissapeared from workspace, where can I find them?

Hi, This new parts you will get in local cache directory location. You log call to PTC technical support they will help to resolve this issue. Another method is as follows: The cache files having file extension.wfcont The server side parts (Uploaded or check-in)name will start with sid_ and system generated number. The newely created files name start with lid_ and systen generated number. Copy this lid_xxxxx files to one folder. Rename files extensions to .prt and try to open in pro-e, same try for .drw & .asm. This process requires more time but you can retrive your data by this process.
