7. A system for obtaining other documents of a operating system file storage via flags, the system comprising: a processor; and a memory having computer-executable instructions stored thereon, wherein the computer-executable instructions are configured for: providing a flag library storage that includes a plurality of pregenerated flags that include metadata indicating a flag type, wherein the flag library is stored independently of any document files, wherein the plurality of flags are independent of any document file type; providing a file storage accessible from an operating system of a computing device, wherein the file system includes a plurality of document files having a plurality of file types based on a plurality of respective applications associated with the operating system; providing an operating system user interface, wherein the operating system user interface includes a document file icon pane and a document tag pane; receiving a selection in the document file icon pane of the operating system user interface of at least one of the document files in the file system; determining whether the at least one selected document file includes type metadata that points to one of the plurality of flags located in the flag library storage that is stored independently from any document files, wherein the flag type metadata includes metadata applied to the document file in entirety stored in a peer relationship with metadata embedded in the document file and applied to one document object embedded in of the document file; when the at least one selected document file includes flag type metadata that points to one of the plurality of flags located in the flag library and the metadata is applied to the document file in entirety: determining the flag type based on the flag type metadata, and populating the document tag pane with icons of at least one other document file having a same flag type, wherein the at least one other document file has a file type different than the at least one selected document file, wherein a respective application of the at least one other document file is different than a respective application of the at least one selected document file; when the at least one selected document file includes flag type metadata that points to one of the plurality of flags located in the flag library and the flag type metadata embedded in the document file is applied to the one document object embedded within the document file: determining the flag type based on the flag type metadata, and populating the document tag pane with a quantity of embedded flags in any other document of the file storage in having a flag related to the flag type.
7. A system for obtaining other documents of a operating system file storage via flags, the system comprising: a processor; and a memory having computer-executable instructions stored thereon, wherein the computer-executable instructions are configured for: providing a flag library storage that includes a plurality of pregenerated flags that include metadata indicating a flag type, wherein the flag library is stored independently of any document files, wherein the plurality of flags are independent of any document file type; providing a file storage accessible from an operating system of a computing device, wherein the file system includes a plurality of document files having a plurality of file types based on a plurality of respective applications associated with the operating system; providing an operating system user interface, wherein the operating system user interface includes a document file icon pane and a document tag pane; receiving a selection in the document file icon pane of the operating system user interface of at least one of the document files in the file system; determining whether the at least one selected document file includes type metadata that points to one of the plurality of flags located in the flag library storage that is stored independently from any document files, wherein the flag type metadata includes metadata applied to the document file in entirety stored in a peer relationship with metadata embedded in the document file and applied to one document object embedded in of the document file; when the at least one selected document file includes flag type metadata that points to one of the plurality of flags located in the flag library and the metadata is applied to the document file in entirety: determining the flag type based on the flag type metadata, and populating the document tag pane with icons of at least one other document file having a same flag type, wherein the at least one other document file has a file type different than the at least one selected document file, wherein a respective application of the at least one other document file is different than a respective application of the at least one selected document file; when the at least one selected document file includes flag type metadata that points to one of the plurality of flags located in the flag library and the flag type metadata embedded in the document file is applied to the one document object embedded within the document file: determining the flag type based on the flag type metadata, and populating the document tag pane with a quantity of embedded flags in any other document of the file storage in having a flag related to the flag type. 12. The system of claim 7 , further comprising filtering the operating system user interface by flag type.
