Locked file ... or not?

    Question

  • I run SyncToy 2.1.0.0 between two Windows 7 Pro sp1 x64 machines.

    I recently sync'ed about 700 jpg files.  The summary screen noted:

    SyncToy action was 'Synchronize'.
    SyncToy options were:
        Active for run all
        All files included
        No files excluded
        Do not check file contents
        Include read-only files
        Include hidden files
        Include system files
        Backup older files (send to Recycle Bin)
        Some subfolders included
    SyncToy run took 00:13:39:596.
    Copied 1,843,210,792 bytes in 709 files in 00:13:39:596.
    Bytes per second 2,248,925.4, files per second 0.9.
    Avoided copying 43,717,156,079 bytes in 33,953 files that did not require action.
    Saved approximately 05:23:59:131 by not copying all files.
    Warning: 21 failures occured.
    You can retry by selecting "Run" again or select "Preview" to see
    the operations that remain to be performed.

    I looked at the log, where all 21 of the errors were similar to this:

    Error: Unknown error. The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020) Copying \\machine 1\path\filename.JPG to \\machine2\path\filename.JPG

    There were no other processes on either machine that were accessing any of those files.

    I re-ran "Preview" and SyncToy said that there was nothing to do.

    So I looked at the 21 files and in fact they had been copied.  Thus, the process did access the file and copied it .... so why were the errors thrown?
