Hi Russell, >> 1. What version of Windows? 1) I am using Windows XP. >> 2. What error does it finish with (preferably the DllError). 2) Without password DllErrCode = 606077985 , with password DllErrCode = 605443072 >> 3. Does it happen each time. 3) It happens each time >> 4. Are you encrypting to the file. 4) Happens irrespective of giving password to the Zip. Below I have added the OnMessage events details. FSpecArgs = C:\Delit\Chk\*.* I have deliberately taken only one file (open) to reduce the size of trace messages. Observation: This happens only to files that give following message while copying via windows explorer (ex: Outlook.pst, Absolute database ) 'Cannot copy SSIIPL.dat : The process cannot access the file because another process has locked a portion of the file.' >> It is never a good idea to zip an in-use file, also not a good idea to rely >> on file access settings to prevent zipping. I just need the open file to be skipped.
