I'm downloading CyanogenMod-10.1 source on a low speed broadband. About 4GB of source is downloaded . In that 4GB, there is a big project "CyanogenMod/android_frameworks_base" which alone took 1GB of download without any interruption.

Ok now, after 4GB of download, my internet got disconnected and I had to stop (ctrl + z) repo sync while it was downloading the project "CyanogenMod/android_prebuilt". Before I stopped repo sync the android_prebuilt got downloaded till 250MB and is at 42percent.

I checked the working folder and there is a file "tmp_pack_df5CKb" of size 250MB in the path "$WORKING_DIR/.repo/projects/prebuilt.git/objects/pack/" .

Then I restarted repo sync and it was downloading the android_prebuilt project. But I'm not sure if it was downloading from start or resuming from 250MB. While downloading this time , the previous "tmp_pack_df5CKb" isn't deleted and the content is being downloaded to a new file "tmp_pack_HPfvFG".

I heard repo sync cannot be resumed for a project. But here, since the previous file isn't deleted I want to ask if android_prebuilt is resuming or downloading from start again?

Now that my high speed internet is over (current speed 256kbps), I'm not sure if I can download the remaining ~4GB if single project is in size 500 MB.
