Since 1992, the United States Department of Justice’s Antitrust Division has been investigating a wide-ranging price fixing conspiracy among participants in the commercial explosives and ammonium nitrate industries. The appellants, who are plaintiffs in a civil suit related to this conspiracy, filed a Freedom of Information Act request with the Antitrust Division to disclose certain documents related to its investigation. Specifically, the appellants sought documents related to the criminal investigations of three corporations and one individual who have already pleaded guilty to price fixing charges. The Government withheld the information, claiming that disclosure reasonably could be expected to interfere with its ongoing investigation. Seeking an injunction to require production of the documents, the appellants filed suit in the district court which, following an in camera review of randomly selected documents, awarded summary judgment to the Government. We affirm.
I.
Along with other plaintiffs, Solar Sources, Inc. and Amax Coal Company are currently pursuing civil antitrust claims arising out of a price fixing conspiracy in the commercial explosives and ammonium nitrate industries. Their suit (the Arch Minerals litigation), was filed in the Southern District of Indiana. In August 1996, the Judicial Panel on Multidis-trict Litigation transferred the case for all pretrial matters to the District of Utah. The Arch Minerals litigation is presently in the pretrial stage.
On September 25, 1995, the appellants filed a request seeking disclosure under the Freedom of Information Act (FOIA), 5 U.S.C. § 552, of “all documents relating to investigations or proceedings” in four criminal antitrust casеs arising out of the Government’s commercial explosives price fixing investigation. The defendants in these four cases — ICI Explosives USA, Inc.; Dyno Nobel, Inc.; Mine Equipment & Mill Supply, Inc.; and Withers Waller Caldwell, Jr., an officer for ICI — had pleaded guilty to criminal charges filed against them in the Northern District of Texas. The three corporate defendants are also some, but not all, of the defendants in the Arch Minerals litigation; the appellants made their FOIA requests in furtherance of their civil case.
Although the Government hаs concluded its criminal proceedings against the four defendants named in the appellants’ FOIA request, the Antitrust Division’s investigation is ongoing. 1 Therefore, after releasing 96 pages of publicly-filed documents from the four concluded cases, the Government refused to disclose any other information related to its ongoing investigation. The Government rested its refusal to the FOIA request on Exemption 7(A), which excludes “records or information compiled for law enforcement purposes” to the еxtent that production “could reasonably be expected to interfere with enforcement proceedings.” 5 U.S.C. § 552(b)(7)(A). The appellants then filed *1036 suit in the district court, seeking an injunction to require disclosure of the requested information.
The Government filed a motion for summary judgment, asserting that the requested documents properly were withheld under Exemption 7(A). In support of its motion, the Government submitted a signed declaration from Ann Lea Harding, Chief of the FOIA Unit for the Antitrust Division. The declaration explained the nature of the Division’s ongoing criminal investigation, as well as the manner in which the appellants’ FOIA request was processed. Harding’s declaration then explained that the information that was responsive to the appellants’ request constituted 1763 linear feet of documents, as well as over seventy million bytes of computerized information. The declaration stated that all of the requested information fell into one or more of the following categories: (A) correspondence between individuals or entities and the Antitrust Division regarding grand jury subpoenas issued by the Division in its investigation of the explosives industry; (B) documents submitted by various individuals or entities pursuant to grand jury subpoenas served upon them; (C) various documents or pleadings filed under seal, internal Division material related to grand jury management, and other internal Division memoranda; (D) transcripts and summaries of grand jury testimony and exhibits; (E) various documents stored only in computer form, including internal Justice Department memoranda regarding the investigation, indices of all documents and databases, outlines for proposed grand jury testimony, lists, and summary charts; and (F) computerized databases of selected portions of the information already listed above. Category B, which consisted of more than five million pages of material, comprised the vast majority of the documents.
More specifically, Harding asserted that all of the information fell into at least one of the following subcategories: (1) details concerning allegаtions that gave rise to the investigation; (2) statements or interviews of witnesses, subjects, and targets; (3) details about the progress of the investigation; (4) confidential business information; (5) leads to future interviews and targets of grand jury subpoenas; (6) details about the conduct that led to the guilty pleas by the subjects of the appellants’ FOIA request and similar information about individuals and firms that have not yet been charged; (7) Division anal-yses and recommendations; and (8) offers of settlement and negotiations concerning sentences and fines. Harding’s declaration further explained that the categories were not mutually exclusive; for example, category B contained information attributable to subcategories 1, 2, and 4 through 6. The declaration further explained that disclosure of the withheld information would chill third parties from disclosing confidential business information that is necessary to the investigation and allow potential defendants to alter or destroy yet-undiscovered evidence, to intimidate or rеtaliate against witnesses, and to determine the scope and direction of the Government’s investigation.
The district court determined that it needed more information regarding the withheld documents to determine the propriety of the Government’s assertion of Exemption 7(A). 2 The court declined to require that the Government compile a Vaughn index. 3 The court determined that it would review specified selections of the withheld documents in camera. Pursuant to the court’s instructions, the Government produced documents from categories A through D selected from randomly-chosen specified locations in the Government’s files. The Government produced approximately 3000 pages for the court’s in camera review, along with an in *1037 dex of the sample documents that explained why they satisfied Exemption 7(A).. The Government also explained that of the 3000 pages that it had provided the court, 15 documents totaling 26 pages could be released to the appellants. However, the Government argued that this small percentage (less than one percent) was not “reasonably segregable” from the responsive documents and that it was therefore not required to produce the estimated one percent of disclosable pages out of the total of over five million. See 5 U.S.C. § 552(b).
Following its thorough in camera review of the selected documents, the district court found that the Government had properly withheld the documents under Exemption 7(A). The court found that “producing the requested documents to plaintiffs in this case reasonably could be expected to interfere with ongoing enforcement proceedings” and that it was “satisfied from its inspection of the random documents that it is impossible for the Division to separate, from the more than 5,000,000 pages of documents and the more than 70,805,509 bytes of computerized data, information that is applicable only to those defendants named in the plaintiffs’ FOIA request.” 4 Thus, the court awarded summary judgment to the Government.
II.
The Freedom of Information Act generally contemplates a policy of broad disclosure of government documents, and serves the basic purpose of “ensurpng] an informed citizеnry, vital to the functioning of a democratic society.”
NLRB v. Robbins Tire & Rubber Co.,
Exemption 7(A) does not permit the Government to withhold all information merely because that information was compiled for law enforcemеnt purposes. Instead, “an agency seeking to shield records or information behind [the Exemption] must show that disclosure could reasonably be expected perceptibly to interfere with an enforcement proceeding.”
North v. Walsh,
We review a district court’s determination on summary judgment with respect to a FOIA request by determining whether the district court had an adequate factual basis to make its decision and, if so, whether its decision was сlearly erroneous.
See, e.g., Becker v. IRS,
The district court in this case was presented with the monumental task of reviewing the denial of a FOIA request comprising millions of pages of documents. The appellants attack the Government’s record-keeping system itself, which they argue effectively allows the Government “to repeal the FOIA by dint of its own improvidence.” However, they have not argued that any of the information was not compiled for law enforcement purposes, and it is “firmly established that an agency is not required to reorganize [its] files in response to [a plaintiffs] request in the form in which it was made.”
Church of Scientology v. IRS,
Moreover, we are satisfied that the district court’s conclusion that the material is exempt from disclosure under 7(A) is not clearly erroneous. The Gоvernment explained to the court a number of ways in which disclosure could interfere with its ongoing criminal investigation. Public disclosure of information could result in destruction of evidence, chilling and intimidation of witnesses, and revelation of the scope and nature of the Government’s investigation.
See Robbins Tire,
We also conclude that the district court did not clearly err in finding that the small percentage of documents that could otherwise be disclosed — less than one percent of the documents reviewed
in
camera— are not reasonably segregable from those documents that were properly withheld. The FOIA provides that “[a]ny reasonably seg-regable portion of a record shall be provided to any person requesting such record after deletion of the portions which are exempt under this subsection.” 5 U.S.C. § 552(b). We have already recognized the principle that govеrnment agencies need not organize their records for the purpose of FOIA compliance. Given this principle, we believe that the statute makes clear that courts should not order segregation when such a process would be significantly unwieldy.
See Lead Indus. Ass’n v. OSHA,
III.
The appellants raise several аdditional arguments attributing error to the district court’s methodology and holding. First, they argue that the court erred in not requiring the Government to file a
Vaughn
index or, alternatively, by not allowing them to review the Government’s
in camera
submis
*1040
sions. In
Wright v. OSHA,
We also do not believe that the district court erred by denying the appellants a review of the
in camera
documents. The FOIA itself explicitly contemplates
in camera
review,
see
5 U.S.C. § 552(a)(4)(B), and the general rule is that counsel are not entitled to participate in
in camera
FOIA proceedings.
See, e.g, Salisbury v. United States,
Finally, the appellants make two arguments that in this case disclosure of the withheld documents would not, in fact, interfere with enforcement proceedings. First, they argue that their request does not relate to any ongoing criminal proceedings, because the Government has already obtained convictions against the individuals about whom they sought information: “How can production ‘sabotage’ cases in which the Government has already prevailed by рlea agreements and criminal convictions?” Although the appellants are correct that the Government has closed its eases against the specific individuals named in the FOIA request, the information that the Government compiled against them is part of the information that it has compiled for an ongoing investigation. The fact that the Government has closed a particular investigation does not make it any less likely that disclosure in this case “could reasonably be expected to interfere with enforcement proceedings.” 5 U.S.C. § 552(b)(7)(A);
see also New Eng. Med. Ctr. Hosp. v. NLRB,
Second, the appellants argue that disclosure in the instant case would actually assist, and not interfere with, the Government’s antitrust enforcement. Cognizant of the powerful private antitrust remedies created by Congress, the appellants note that “the purpose of giving private parties treble damage and injunctive remedies was not
*1041
merely to provide private relief, but was to serve as well the high purpose of enforcing the antitrust laws.”
Zenith Radio Corp. v. Hazeltine Research Inc.,
The appellants’ argument again еxpresses a fundamental misunderstanding of the broad public purposes of the FOIA. While they claim that the documents they seek “are to be used exclusively to aid private antitrust litigation”, we have indicated that neither an individual’s identity nor his intended use for the documents is relevant to a FOIA request.

IV.
For the foregoing reasons, we affirm the decision of the district court.
Notes
. In its brief to the Cоurt, the Government states that subsequent to the appellants' September 1995 FOIA request, it has secured eleven additional indictments, all resulting in guilty pleas, as well as fines exceeding $11 million. After submitting its brief to the Court, the Government secured indictments of three corporate officers involved in the conspiracy. One of the three men has pleaded guilty to conspiracy charges; the other two are set to stand trial.
. While the Government asserted that it could withhold all the documents under Exemption (7)(A), it also asserted that other exemptions — ■ including Exemptions 3, 4, 5, and 7(D) — could apply to portions of the withheld documents. See 5 U.S.C. § 552(b). The Government reserved the right to assert those exemptions if the district court rejected its 7(A) exemption claim.
. A
Vaughn
index is a comprehensive listing of each withheld document cross-referenced with the FOIA exemption that the Government asserts is applicable.
See Wright v. OSHA, 822
F.2d 642, 645 (7th Cir.1987);
Vaughn
v.
Rosen,
. The court also found that the Government was justified in withholding the category D documents-grand jury testimony and exhibits — under FOIA Exemption 3, which permits withholding information that is "specifically exempted from disclosure by statute ... provided that such statute (A) requires that the matters be withheld from the public in such a manner as to leave no discretion on the issue, or (B) establishes particular criteria for withholding or refers to particular types of matters to be withheld," 5 U.S.C. § 552(b)(3). The court held that Federal Rule of Criminal Procedure 6(e) generally prohibits disclosure of grand jury materials, and that any request for disclosure must be filed in the Northern District оf Texas, where the grand jury is convened.
See-
Fed.R.Crim.P. 6(e)(3)(D) ("A petition for disclosure .. 1 shall be filed in the district where the grand jury convened."). We have held that Rule 6(e) is a "statute” for the purposes of this FOIA exemption.
See Silets v. Department of Justice,
. As we noted in
Becker,
there exists "some tension” between the de novo standard of review that we commonly employ in our review of a district court’s award of summary judgment and the standard that we employ in reviewing a district court’s FOIA exemption determinations.
See
. In this context, the appellants argue that the district court could issue a "protective order” that would limit the use of the disclosed documents, perhaps shielding the documents from, potential targets of the Government's investigation. This argument, however, misapprehends the FOIA’s basic principle of
public
access to
government documents.
The identity of an individual requesting documents under the FOIA, or the reasons for an individual's request, arе simply not relevant to the merits of a FOIA request.
