I have a VB6 program running on Windows 7. It copies a large number of files, and sometimes FileCopyit crashes with violation of access rights (between 60 and 500 files).
I cannot play it using a single file, only during such bulk copy operations does this problem occur.
It doesn’t matter if the source / target is on hard drives, network shares or CDs.
What can cause this problem?
EDIT: My question might be a bit confusing, so here are some more data:
Run 1:
- Start copying 5,000 files
- Access Violation of File # 983
- Access Violation of File # 1437
- File Access Violation # 1499
- Access Violation of File # 2132
- Access Violation of File # 3456
- Access Violation of File # 4320
- Done
Run 2:
- Start copying 5,000 files
- Access Violation of File # 60
- Access Violation of File # 3745
- Done
Observations
- Damaged files are always different
- The number of damaged files tends to decrease if the same batch of files is copied several times in a row.
- Running as an administrator does not matter.
- The application has read / write access to all necessary objects of the file system.
- This issue only occurs on Windows 7 workstations.
