Question about App Storage

[Guest cagster]

I have FLP 1.5 custom rom installed and storing apps on the SD. This seemed to be working ok and I had around 79MB spare internal storage space.

I installed co-pilot live which is large - the app being 13mb. After installing this I noticed that the available internal storage had gone down from 79MB to 66.42

So I am wondering whether this is being stored in internal storage. When I look in Application Info Co-pilot takes up 22.71 MB, 13.32.MB Application and 9.39MB of data.

From what I can see when I search ASTRO the application is stored in system/sd/app (com.alk.copilot) and so are all the other downloaded/market applications.

I know this is probably a dumb question but I assume that the path system/sd/app is some sort of virtual mapping to the ext partion of the SD card ?

Is it the 9.39MB of data that is being stored in the internal memory ? I.E. Only the apps are put on the SD card ?

If anyone can provide any info to explain what gets stored where I'd be most grateful - apologies if this information is already on the forum - if it is then I have missed it.

(The maps i have are of course large and these are definatly on the SD card)

Yes, /system/sd/app is where the ext2 partition is mounted... But only the apk files are stored there, the data of those applications are saved on the internal memory of the phone.

I hope I helped :P

A2SD only remaps /data/app and /data/app-s to the ext2 partition on the SD card. Any data files used by the system or applications will be stored on the /data partition which will slowly reduce space. The biggest reason for space to go down is the dalvik-cache which the system stores on the /data partition by default. Most people with fast SD cards of a class 4 or class 6 will move the cache to the SD to free up /data so the system has more room for other cache files, and for general speed up of the phone usage.

Thanks to both of you.

I moved the dalvik-cache already to the SD card.

How can I see how much space there is left for RAM ? Again sorry if this has been answered already. Is there anything you can do to maximize the space available for RAM ?

Also it would be great if there was a program which could remove all "cached" data from all installed apps rather than having to do this for each app manually - does anyone know of such a tool ?

Use a widget, eg.: Free Memory
