ways to Identify duplicates and delete duplicates exist as tools in Arctoolbox for attributes and if the shape field is being compared, the geometries. There is some tolerance, but 'generally close' isn't really supported

Find Identical and Delete Identical but you need an Advanced license

thanks for your help but I have too many partial data. Is there any other method which facilitate my processes?

by partial, do you mean that pieces of a polyline overlap but not the whole pair?

Haven't had the need to use the Finding Duplicate Geometry in the Data Reviewer if you have it

I have ArcGIS 10.4. I attach the gdb. I try to delete layers which overlap each other and delete others until getting one feature. The features are partial.

I haven't had a chance to look at the data, but can you clarify "delete layers which overlap each other?" If you have two layers that overlap each other, do you want both to be deleted or just one? If just one, which one? How do you determine which is the correct overlapping layer to delete and which to leave?

If the duplicates lines are in one layer, use Dissolve—Help | ArcGIS Desktop tool. then explode ( advanced editing toolbar ) them again or use Multipart To Singlepart—Help | ArcGIS Desktop

Not sure if this is what you are after, but I'll throw it out there:

If the issue is that the lines are roughly parallell and close but not coincident, one solution to make them coincident so one could then follow up and dissolve them down to a single line is Integrate:

Integrate—Data Management toolbox | ArcGIS Desktop

Caution - this tool alters the original data (i.e. does not make a new output like most geoprocessing tools do), so be sure to save off copies of your original data as backups. Also, one typically has to do several trial runs to find the best XY Tolerance setting for use in the tool to provide the maximum effect with the least distortion.

I have a data which created in irregular way so there is so many data which overlapped or intersected with each other. It is important that which data I deleted.

Thanks for your help. I am trying to use your method now.

This tool is all about that I want to create. However, I do not use ArcGIS Pro Thanks for your help.

I tried the solution and it works The only thing that I should do is allocating different layers from each other and applying this method for each of them severally.

You do not need ArcGIS Pro to use the Integrate tool. Integrate—Help | ArcGIS for Desktop

Setting up database topology rules might also help with identifying errors and cleaning up the data.
