Dear all, I was browsing through my photo gallery and noticed that there are a whole list of files named fixedstroke.png and fixedstroke2.png with the file size of 86 bytes each. All of them are located under storage/sdcard0/Android/data/com.android.calendar/serial/xxxxxxxxxx (10-digit-number)/fixedStroke.png. When I opened them with ASTRO Image Viewer, it just shows a page with grey and white pixels. I'm just wondering if I can safely delete them as they are building up at an alarming rate! They breed like rabbits! Thank you!
