child pornography. As the parties are familiar with the facts, we do not repeat them here

. Gonzales raise s three issues on appeal

. For the reasons below, we affirm the district court. First, Gonzales argued that the district court abused its discretion by finding that the Government presented adequate foundation for (1) the reliability of Torrential Downpour, (2) the “mirror image” process used to clone the seized tablet, ( 3 ) the processes underlying the Forensic Took Kit ( FTK ) tool, and ( 4 ) the processes underlying the Independent Evidence Finder ( IEF ) tool. We review the district
court’s determinations about authentication and foundation for an abuse of discretion

. United States v. Estrada

- Eliverio , 583 F.3d 669, 672 (9th Cir. 2009); United States v. Tank , 200 F.3d 627, 630 (9th Cir. 2000). “To satisfy the requirement of authenticating or identifying an item of evidence, the proponent must produce evidence sufficient to support a finding that the item is what the proponent claims it is.” Fed. R. Evid. 90 1(a). First, t he Government presented two witnesses, Detective E rde ly and Special Agent Cullen, who testified to the accuracy and reliability of Torrential Downpour, the mirror image process, the FTK tool, and the IEF tool and explained how each electronic forensic tool functions. Because the testimony presented at trial adequately explained the reliability of the process es underlying all four categories of digital forensic evidence challenged by Gonzales , the Government satisfied its3

burden of showing that Torrential Downpour, the mirror image process, the FTK program, and the IE F program were what the Government claimed they were. See Fed. R. Evid. 901(a). The district court did not abuse its discretion

. Second, Gonzales argued that the Government failed to prove he knew the images underlying Counts 4, 7, and 8 were child pornography because it presented no evidence that he opened or viewed those files

. We review a forfeited challenge to the sufficiency of the evidence for plain error

. United States v. Lopez , 4 F.4th 706, 719 (9th Cir. 2021). The crime of distribution of child pornography requires that a defendant knew that the image at issue depicted a minor engaged in sexually explicit conduct. 18 U.S.C

. § 2252

. But the G overnment need not present direct eviden ce that the child pornography files were accessed or opened in every case to establish knowledge

. See, e.g. , United States v. Ruiz

- Castelo , 835 F. App’x 187, 189 (9th Cir. 2020) (explaining that “the g overnment was required to prove Ruiz

Castelo’s knowledge that the video contained sexually explicit conduct with a minor, not that Ruiz

- Castelo necessarily viewed the video before he distributed it”). What is more, t he fact that the forensic evidence did not show that the files containing the images underlying Counts 4, 7, and 8 had been opened does not undermine the convictions on those counts because c ircumstantial evidence of the number of child pornography files and their location may be sufficient to prove knowledge. United States v. Hardrick , 766 F.3d 1051, 1057 (9th Cir. 2014) . Here,4

Gonzales admitted that he used the tablet to search for child pornography during the relevant timeframe , he possessed many child pornography files in an unusual location on the device, and he successfully shared other child pornography files with the FBI that he viewed but that were no longer on his device

. The Government therefore presented sufficient evidence a t trial for a reasonable juror to conclude that Gonzales knew the images underlying Counts 4, 7, and 8 showed minors engaged in sexually explicit conduct. Third, Gonzales argued that the district court improperly delegate d the setting of his restitution payment schedule to the Bureau of Prisons (BOP). Because Gonzales did not object to the district court’s order setting a restitution payment schedule at sentencing, his argument is reviewed for plain error. See Fed. R. Crim. P. 52(b ); United States v. Olano , 507 U.S. 725, 732 (1993) . To be sure, the district court cannot delegate the setting of a restitution payment schedule to the probation office or the B OP. United States v. Gunning , 401 F.3d 1145, 1150 (9th Cir. 2005)

. But the BOP nonetheless has “independent power to administer the [Inmate Financial Responsibility Program (IFRP)] , ” Ward v. Chavez , 678 F.3d 1042,
10 46− 47 (9th Cir. 2012) , a nd may require inmates who participate in IFRP “to pay restitution to victims at a higher or faster rate than was specified by the sentencing court, ” United States v. Lemoine , 546 F.3d 1042 , 1044 (9th Cir. 2008 )

. And although the district court’s judgment here states that “payment shall be made through5

[IFRP],” Gonzales fails to show that his subsequent participation in that program was not voluntary on his part. Thus, because Gonzales was a voluntary participant in IFRP, the BOP had the authority to adjust Gonzales’s restitution payment schedule. The district court therefore did not plainly err

. We therefore AFFIRM the district court
