Can I move apps to internal USB storage?

Question

I have a Samsung Galaxy S. I am getting a "Low on space - Internal phone storage is getting low" error.

When I go to Manage Applications it shows the internal memory as 1.9GB used, 6.0 MB Free. When I click "On SD Card" it shows "USB Storage 681 MB Used, 13 GB Free". There is no external SD card in the device.

When I select an app and click "Move to SD Card" it just returns the following error:

Failed to move application. Not enough memory.

Is there any way I can move the apps to the internal USB memory?

Update: I've reset the phone to factory settings so no longer get the error about space getting low and internal storage is almost empty. I've installed a couple of apps and still get the same error when I try migrate them to USB storage.

Sounds like you need to clean up your internal memory first before you can do anything. There's three ways I can suggest to free some up:

1. Clean out your app caches to free up space (browsers and maps are usually the worst offenders): you can use an app like SD Maid (it's tiny, you should be able to install it) or by going into the application management section (Settings->Applications->Manage Applications->All, then click on an app name) and manually clearing out app data for hogs like Google Maps and the like using the Clear cache button (note: don't clear the app data! just the cache).
2. Uninstall some apps, then reinstall them after you've moved other apps to the SD card.
3. Root your phone and uninstall bloatware / system apps you don't use with an app like Titanium Backup (make sure you back up the apps first in case you need them later). Note: this will keep your phone from being able to install carrier Android updates in the future.

Android is usually pretty good about auto-installing apps to non-system storage when possible. Does your version have an option to prefer installing to SD set?
