These posts are making me snoop around, too, to see what all is going on. We
all realize that designing software to edit video has to be among the more
difficult software challenges around (more so than databases, internet
communication, web pages, bookkeeping, etc.) Therefore I can accept the
usefulness of having temp files to help make editing more responsive, but
the whole area seems unnecessarily obscure, as if it should be kept as a
trade secret.
So I found the mcdb files, these are in subdirectories under a drive name!
This machine has subdirectories C, D, G, X, Z, and Iomega-blah, and UNC! So
sure enough, those would be computer-specific. I also found the cfa, pek,
mpeg, and mpgindex files mentioned in this thread.
But I'm not too quick to call their _1, _2, _3 annotation to a file-name
"dumb", since there might be a valid reason. For example, I noticed they
refer to camera files. And wouldn't you know it, camera file names are not
unique. When I have a 3-camera event one day and another one a week later
for the same project, it happens that I'll import two different files with
the same names into the same project, because each camera (same brand) makes
files using the same naming convention.
Therefore I wouldn't want PPro to go overwriting temp files just because the
name is the same.
Maybe the Adobe experts should be more complete about describing the
mechanism, explaining all the files which are created, where they reside,
what effect manual deletion might have, whether a file is critical or can be
manually deleted, proportional sizes, etc. so we wouldn't have to go through
this guessing exercise.

Subject: Re: [AP] ...re-indexing on portable drive
Wow! Now that I've taken a look in the Media Cache Files folder on my
portable drive, I've discovered that Premiere has wasted over 29
gigabytes of space by keeping old versions of conformed audio, audio
peak files, and indexed video files on the disk each time it
re-configures or re-indexes.
That's *really* dumb! Not only has Premiere found the previous
versions of the files so it could renumber the new files accordingly,
but it completely ignored them and ground through everything once
again. Then it left all the old ones in place to eat up disk space.
I just removed all the old versions, fired up the project, and it
runs just find without re-configuring or re-indexing.
Some Adobe engineer somewhere has a lot of explaining to do.
