The defragmented file is made using _Defrag at the end of its file name.

The file handling during defragmentation proceeds as follows: For example, if you defragmented JoshuaTreeNP.mxd, the new file is JoshuaTreeNP_Defrag.mxd. By default, a new document file is created in the same folder as the original file and the name of the new file is the same as the original file name with _Defrag appended to it.

There are different options for placement of the defragmented documents. You can defragment a single document file, all ArcGIS documents in a particular folder, or all documents found in folders beneath a point in the file tree. Alternatively, you can open the utility from All Programs > ArcGIS > Desktop Tools. By default, that location is :\Program Files\ArcGIS\Desktop\Tools.

The utility is located in the Tools folder of the ArcGIS Desktop installation directory. This utility is useful if your .mxd files are large in size. mxd file to potentially reduce the file size. Probably not all the resources are in this list, please use the ArcGIS Search tool looking for: "personal geodatabase".The ArcGIS Document Defragmenter utility defragments the storage inside an. Comparing the three types of geodatabases.Users like the string handling for text attributes. Notes: Often used as an attribute table manager (via Microsoft Access). Security and permissions: Windows file system security.ĭatabase administration tools: Windows file system management. Versioning support: Only supported as a geodatabase for clients who post updates using checkout and check-in and as a client to which updates can be sent using one-way replication. The effective limit before performance degrades is typically between 250 and 500 MB per Access database file. Storage format: All the contents in each personal geodatabase are held in a single Microsoft Access file (.mdb). Concurrent use eventually degrades for large numbers of readers. Number of users: Single user and small workgroups with smaller datasets: some readers and one writer.

Note: Personal GeoDatabases were introduced by Esri in ArcGIS for Desktop 8.0 (1999).ĭescription: Original data format for ArcGIS geodatabases stored and managed in Microsoft Access data files.(This is limited in size and tied to the Windows operating system.)

Using ODBC (Microsoft Open Database Connectivity).

Sample file(s): Personal GeoDatabases sample files.

Technical description/specification: Not available.

Originally developed by: Microsoft (1992).

Purpose: Store, query, and manage both spatial and nonspatial data.
