Volume Shadow Copy Service (Windows only)

FreeFileSync supports copying locked or shared files by creating a Volume Shadow Copy of the source drive. This feature can be configured via Menu → Advanced → Global settings: Copy locked files.

Note

  • The volume snapshot created by the Volume Shadow Copy Service is used when copying locked files only.

  • Accessing the Volume Shadow Copy Service requires FreeFileSync to be started with administrator rights.



    Troubleshooting

    If you experience problems using the Volume Shadow Copy Service a renewal of registration might help. Create and execute a *.cmd batch file with the follow content or enter directly via command line:

    cd /d %windir%\system32
    Net stop vss
    Net stop swprv
    regsvr32 ole32.dll
    regsvr32 oleaut32.dll
    regsvr32 vss_ps.dll
    Vssvc /register
    regsvr32 /i swprv.dll
    regsvr32 /i eventcls.dll
    regsvr32 es.dll
    regsvr32 stdprov.dll
    regsvr32 vssui.dll
    regsvr32 msxml.dll
    regsvr32 msxml3.dll
    regsvr32 msxml4.dll
