It seems that now the only answer to your predicament is to install the firmware again. Because you have tried the master reset, that means that you have lost your data as it is, you have nothing to lose if you re install the firmware.

I accidentally deleted some unfamiliar files on my file manager on both phone and memory card. and then i found that my music player does not work properly anymore. i tried to play a song but it doesnt....

You could try backing everything up and doing a master reset, but back everything up first (its so important I said it twice). to do master reset just dial *#7370# and accept. after the master reset you can restore your files by restoring it from the back up.

These are executable files. If these file are in your memory card, they must be viruses if they are not applications you downloaded. You will have to scan your memory card with an anti virus, if that doesnt work, backup the files you need on pc, then format your memory card and everything will be deleted.
If the files are in your phone memory, master reset your phone to factory settings and the files will be removed.
Back up all your files to the memory card or pc before master resetting.

Phone memory full all apps not working

Try to delete messages, those are not too important to you. If you want to make the process quickly, try to delete video file or picture files, those are not too important to you. This way you can free up space in your memory especially if this is built in.

And for hassle free, don't overcrowd your memory of too much application, message, picture or video file. You gonna delete some of it or backup it up from time to time.

Razr lock up

first try and do a master clear and reset and see if that works.....i really don't think deleting the file would help that , you may also need to try reflashing the firmware if the master reset/clear does not fix the problem.
