The Fife outfit - penalised 15 points by the Scottish Football League after calling in administrators - dropped into the play-off place with Saturday's 2-1 defeat to Airdrie. They now face Forfar in a two-legged semi-final, with the first meeting on Saturday at East End Park.
Bryan Jackson, business restructuring partner with accountants BDO, is now running the club after it was placed in administration to protect itself from a winding-up order launched by Her Majesty's Revenue and Customs over an outstanding £134,000 tax bill.
Dunfermline supporters have raised almost £50,000 to help fight their bid for survival and Jackson appealed for them to make "one final push" by turning out for Saturday's first leg encounter with the Loons.
Jackson said: "The response from the fans, PARS United, the club, and the wider community has been overwhelming over the last few weeks.
"A special thank you must also be given to the volunteers who have helped collect donations to the club. The fans have been unbelievably generous in donating nearly £50,000 and this money has been essential to keep the club going by paying wages and to keep DAFC financially afloat during April and May.
"The fact that the club is now facing play-offs to remain in the First Division means that we need everyone to keep supporting the team in the coming weeks. I cannot stress how important it is that support is maintained during the forthcoming games.
"(Manager) Jim Jefferies and the players have shown their commitment to the club on the pitch and the response of the fans has matched this commitment off the pitch. We need to keep up this level of effort over the closing weeks of the season to make sure that DAFC keeps its place in the first division and has sufficient funds to continue to operate."
Jackson confirmed ticket prices for the match against Forfar would be reduced to £10 and £5 and said he expected a big crowd.
He said: "One final push is needed over the next month to keep this historic club going and, given the support the club has already received over the last six weeks, I believe that the fans will come out in their thousands to boost the crowds this weekend and in the rest of the play-offs."
