The next tranche of 25 declassified files related to Netaji Subhas Chandra Bose will be released on Friday.
"Culture Minister Mahesh Sharma will release the next set of 25 files pertaining to Bose Friday," an official said.
Last month, the minister had released 50 declassified files relating to the leader on web portal www.netajipapers.gov.in.
Similarly, as many as hundred secret files were made public by Prime Minister Narendra Modi on Netaji's 119th birth anniversary on January 23.
In October last year, Modi had met the family members of Netaji and announced that the government would declassify the files relating to the leader whose disappearance 70 years ago remains a mystery.
While two commissions of inquiry had concluded that Netaji had died in a plane crash in Taipei on August 18, 1945, a third probe panel, headed by Justice M K Mukherjee, had contested it and suggested that Bose was alive.
