    I have a ton (like 35) of these files on the root of my SD card...

    DiskCacheIndex12839.tmp
    DiskCacheIndex47600.tmp

    etc.

    OK to delete all of them, or have to leave ones w/current date?

    Where are they coming from, why do I have so many!?

    Thanks!

    I saw them too - so I deleted them after noticing they had not been updated in a day or so.

    No adverse effects, but I have also switched out the ROM 3 times since, so....

    Yeah, me too...lots of ROM switching, which I think may be be generating these.

    I tried google and didn't see anything specific...

    Hi. Cache is simply temp files used to speed up performance on your droid. Here is the web definition from www.looselycoupled.com :"Short-term storage. Cache is used to speed up certain computer operations by temporarily placing data, or a copy of it, in a location where it can be accessed more rapidly than normal. For example, data from a storage disk may be cached temporarily in high-speed memory so that it can be read and written more quickly than if it had to come directly from the disk itself; or a microprocessor may use an an on-board memory cache to store temporary data for use during operations."

    I delete mine daily and my droid runs like a dream.

    Yeah, we know what cache is, but they did not use to appear on the phone, and all of a sudden they were there. We were trying to figure out if there was a detrimental effect to manually deleting them.

    Having deleted mine several times, now, I know that there is not, provided that I make sure that none has a current date....

    johnlgalt, I was only trying to help those who didn't realize what cache was...I thought it easier to define it before I answered. It was not my intent to offend anyone, just trying to help...like everyone else on the forum.

    I see, my error then. I didn't consider it in that light.
