Free up memory on s60v3 and v5 device memory card

Many months ago, i had found a file named "glxmdstn" , no extension, in E:\private\101ffc31 . It had a woohping 367 mb size. But i didnt know how to delete it. Now i know and i want to share it.




On googling i found that it was the system file which stored images and video thumbnail cache. However problem was that it was recreated everytime it was deleted.






SOLUTION~:
1. Connect memory card to pc or use any device other than nokia.
2. Now delete the glxmdstn file.
3. Create a text or any other file, and write anything in it to give it some memory (i used 7 bytes file).
4. Delete the extension of the file and rename it to glxmdstn.
5. Now place it in the folder E:\private\101ffc31
6. Tick read-only attribute.
7. Restart the phone. Thats it!

Now the file will be un-writable to the system. So it wont be able to store any thumbnail cache data. Hurray you saved your memory!
