Hi and Welcome to the Community!
A little background, if I may...there are three types of potential memory on a BB: 1) Application Memory, 2) Device Memory, and 3) Media/SD Card Memory.
Application Memory -- This is the most crucial; it is the protected (not user accessible), dedicated, and fixed (in size) space that is available as the destination for the installation of applications (plus some application storage, overhead and such). You cannot touch AppMemory. You cannot improve the maximum AppMemory that your BB has. It is what it is. Applications can only install here...there is no option.
Device Memory -- This is space on your BB that you can touch to store files, pictures, media, etc. Typically, it is not terribly large, but it is available to you.
SD/Media Card Memory-- This is what it says...your SD card, for you to store files, media, pictures, etc. It can be as large as your BB OS can support...see this KB:
On some devices/OS levels, you can only see "File Free" (Options > Status), which I think is equivalent to AppMemory. On other devices, you can see all three memory usage levels (Options > Memory). Here are some guidelines to use:
Lastly, it is always important to properly close applications when you are done with them. Using the Back or the Red key will not do this -- those leave it to the app to decide what to do...and some will leave themselves resident in memory, consuming resources on your BB, slowing the overall performance. Rather, to close an app, press and select "Close" or "Exit"...that will force the application to be closed, freeing up for your new use the resources it was consuming. Some apps will always remain running (typically -- BBMessenger, Browser, Homescreen, Phone, and Messages)...but, you should still close them properly - especially the Browser...if it is left on an active web page, it will not only consume extra resources but battery power as well.
Further, anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure. Some have taken to doing this on a regular basis as a preventive measure...some as frequently as once per day. Others have obtained the QuickPull app to automate a simulated Batt-Pull.
Now, as to your idea about deleting files...this won't help...the memory that is at issue is AppMemory...but files are stored in either Device or Media Card Memory, so deleting them has no affect on AppMemory.
One way to recover memory is a clean start over -- reload your OS clean, re-install your (now more limited quantity of) apps, and restore your data.

Hey, got your tweet.
I can see there are lots of .rem and .dat files, I am not sure if I can delete them and free up some space.
Read all that Sdgardne wrote you. But if you have ".rem" files on your device, you have your media card encrypted and if you reload the OS first, then you'll lose access to viewing or moving the encrypted picture and media files elsewhere, like on your PC. So, first, go to Options > Security > Encryption and turn off all encryption.
Second, give us some actual numbers of the memory on your device, or memory free, at Options.> Device > Storage.
What are ALL of the numbers there?
