MEMORANDUM **

The district court correctly concluded that the Shandel Clay Milligan’s habeas petition was untimely. Equitable tolling based on Milligan’s claim of inadequate library resources at High Desert State Prison was not justified. Although we have previously said that deficient prison library resources may be grounds for equitable tolling, the inquiry is “highly fact-dependent.” See Whalem/Hunt v. Early, 233 F.3d 1146, 1148 (9th Cir. 2000) (en banc). The evidence presented shows no causal link between the library’s limitations and the year delay in Milligan’s petition. The district court properly concluded that Milligan’s “vague and unsubstantiated assertion does not warrant [equitable] tolling.”

Although equitable tolling may be justified where a prisoner is deprived of access to his files, see Lott v. Mueller, 304 F.3d 918 (9th Cir. 2002), such basis for tolling cannot redeem Milligan’s petition. For even if we were to accept his unsubstantiated assertion that his files were removed for numerous weeks during each prison transfer, it would be insufficient to account for the enormous delay in filing here.1

*748Statutory tolling cannot make up the deficit. Under the Anti-Terrorism and Effective Death Penalty Act, statutory tolling applies for the period in which “a properly filed application for State post-conviction or other collateral review ... is pending.” 28 U.S.C. § 2254(d)(2). Because Milligan’s original habeas petition was filed and denied on March 26, 1997, at most he would be entitled to one day of statutory tolling,2 which would have given him until April 25, 1997, one day past the statute’s deadline of April 24, 1997. Since he failed to file in federal court until December 11, 2003, he was over &k years too late.

AFFIRMED.
