XnView: MP 0.90 - 64 bit
OS: Windows 7 64bit

.docx and .xlsx (Microsoft Office 2016) file modification timestamps changed on browsing to folder

Effect: Files with .docx or .xlsx extension have their file modification timestamps updated to the current time

To reproduce:
1. Copy/place .docx and .xlsx files in a file system folder
2. Browse to folder in XnView MP
Actual behaviour (bug): .docx and .xlsx files have their modification timestamps updated to the current time

Expected behaviour: file modification timestamps remain unchanged

Thanks to your detailed description I can reproduce the problem.

This problem is supposed to be fixed in XnView MP 0.91. Please check and confirm the bug fix here.

Reproduced the bug with 0.90.
Placed one .xls, two .xlsx and one .docx file in a folder. Their modify date was changed to current by the 0.90 Browser.

Then tested with 0.91 beta 4.
Copied the four mentioned files to the golder again. The file modified dates remained unchanged after browsing with 0.91 beta 4.
Fixed.
