TDMS_DefragmentFile blocks some PC's

[CVI_Benutzer]

Hello

I've a problem with the TDMS_DefragmentFile function.

If I use this function then the windows 7 pc blocks while the function is running.

This problem is not on all windows 7 pc's on some pc's it works properly.

I've used the same file on different pc's.

LabWindows 2013 SP 2

TDMS file format 2.0

TDMS maybe will use quite a lot of the memory to do the defragmentation, depending on how big the file is. Did you observe how much of the memroy useage and CPU usage when doing the defragmentation?
