## Running

You can start profiling files or folders using the Start button, or by selecting the Run / Start Identification menu item.

As files and folders are identified, they are added to the profile, and you can see all the results obtained so far. If you expand a folder, it will show all the files and folders found so far. If you happen to open the folder that is being profiled at that time, you will see its child files and sub-folders appearing under it.

Once you have started a profile running, you cannot choose any further files or folders in it. The specification of which files and folders to process in your profile becomes fixed at the point it first begins running. If you want to subsequently profile other files or folders, then you can do this in a new profile. Results held in multiple profiles can be exported and reported on together.

### Progress

When your profile first starts running, it counts all the files and folders in your profile, including those in sub-folders. Once it has counted them, a progress bar will show how much work has been completed, and how much more there is to do.

The progress bar only gives an estimate of progress. Files which exist inside other files (e.g. zip files) are not accounted for, and in any case, files can be added or removed from your file system while your profile is still running. In most cases, the progress bar gives a fairly good indication of the amount of work remaining to be done. The current file being analysed is also displayed, so even if the progress bar doesn't seem to be moving, you can see that it is still profiling.

### Throttling back

You can control how quickly or slowly DROID processes the files in your profile, and this can be done at any time, whether your profile is running or not. This can take the load off your computer, network or disks if running it would impact you, or other users. By default, DROID works as quickly as it can, but you can tell DROID to delay for a short amount of time between each file it processes.

To slow down or speed up DROID, use the slider control at the bottom right of the main window. When the slider is at the far left of the control, DROID will work as fast as it can (a delay of zero). When the slider is at the far right, DROID will wait for one second between processing each file. Even very small delays can reduce the load on networks and file servers, so the normal useful range for throttling is usually between zero and a hundred milliseconds.

### Restrictions while profiling

While your profile is running, its filter cannot be enabled, and you cannot save it. If you had enabled a filter previously, it will be automatically disabled when your profile is started. Disabling a filter doesn't get rid of it - it just turns it off temporarily. You can turn it on again when the profile is finished, or paused.

In addition, you cannot run any reports or export a profile while it is running. You can report and export other profiles which are not running.

If you want to do any of the above tasks while a profile is running, you can temporarily pause it, carry out the task, and then resume profiling later.

## Pausing

You can pause your profile at any time by pressing the Pause button, or by selecting the Run / Pause identification menu item.

The progress bar will freeze at whatever point it reached, and you will see no further messages about files being analysed in the status bar. Your profile may not pause straight away, as there may be a few outstanding items to be processed in its work queue, particularly if it is in the middle of uncompressing a large archival file. Once paused, there are no restrictions on what you can do with your profile (except that you cannot choose further files or folders once you have started profiling).

### Resuming

You can resume profiling by simple running it again, using the Start command. Profiling will pick up running from the point it left off, leaving all results so far intact. You can also save a paused profile, and then open and resume it at a later date. If the files where your profile was last paused are now different, DROID will attempt to resume by locating the nearest place it can successfully re-start from.
